Bangkok is Thailand's vast and endlessly energetic capital city: a place where gilded Buddhist temples stand in the shadow of luxury hotels traffic-choked boulevards give way to tranquil river klongs and street food stalls serve some of the finest cooking in Southeast Asia.
Thailand: Wat Ratchathammaram: Koh Samui’s Red Temple
🛕 Thailand: Wat Ratchathammaram — Koh Samui’s Red Temple
🏨 A Temple Right on Our Doorstep
Not far from the hotel where we’d checked in for our first night on Koh Samui, we’d spotted something rather special lurking just down the road. We’d barely had time to unpack before we were back on the scooter, heading towards what turned out to be one of the most visually striking temples either of us had clapped eyes on in all our years of travelling around Southeast Asia. The temple in question was Wat Ratchathammaram — a name that takes a bit of practice to say without sounding like you’ve gargled with gravel — and it sits in the southern part of the island, close to the quiet village of Hua Thanon, well away from the bustle of Chaweng and Nathon. This is a part of Koh Samui that a lot of visitors never bother with because they’re too busy nursing a Chang beer by the pool, which is their loss entirely.
Wat Ratchathammaram is more commonly referred to as the Red Temple, and once you see it, it’s blindingly obvious why. The name comes from the extraordinary deep-red terracotta of the ubosot — that’s the principal ordination hall of a Thai Buddhist temple, the sacred inner sanctum where monks are ordained and important religious ceremonies take place — which dominates the entire compound and stops you dead in your tracks the moment it comes into view. The temple also goes by a second name: Wat Sila Ngu, which translates rather magnificently into English as “stone snake.” And yes, before you ask, there are stone-carved snakes absolutely everywhere you look. The compound is crawling with them, metaphorically speaking. Great coiling serpents decorate walls, balustrades, staircases and shrines — it’s like the place was designed by someone with a very specific obsession and an enormous budget for stonework. In Thai and broader Hindu-Buddhist tradition, the naga — the sacred serpent — is a powerful protective deity, a guardian of water, wisdom and the thresholds between worlds, which goes some way to explaining why the whole place is absolutely heaving with them.
Standing in the grounds alongside the ubosot is a golden stupa — or chedi, as they are known in Thailand — a bell-shaped reliquary tower that gleams magnificently in the afternoon sun and can be seen from the road well before you’ve even turned into the temple entrance. In Buddhist tradition, a chedi of this kind is said to enshrine relics of the Buddha himself, though what precisely those relics consist of varies from temple to temple and is generally a matter of faith rather than archaeology. The chedi here is a proper showstopper: compact but immaculately maintained, its gilded surface catching the light in a way that makes it look as though it’s been freshly polished that morning. It probably has been. Thai temples, particularly active ones like this, tend to be remarkably well kept.
🎨 Inside the Ubosot — A World of Bas-Relief and Ancient Stories
The single most extraordinary thing about Wat Ratchathammaram — and there is a fair amount of competition for that title — is the ubosot itself, built from that deep, blood-red terracotta clay that gives the temple its popular name. From the outside, it is already a remarkable sight: the colour is unlike almost anything else we’d seen in Thai temple architecture, which tends to favour white, gold and vivid mosaic tile work. Here, the rich earthen red gives the whole building a brooding, almost ancient quality, as if it has been here for centuries rather than the relatively recent construction that it actually is. Thai temple architecture draws on a long tradition of Sino-Thai synthesis — the blending of Chinese decorative sensibilities with Theravada Buddhist iconography — and Wat Ratchathammaram is a particularly fine example of that fusion in action.
Step inside the ubosot, and the scale of what the temple’s builders achieved really hits home. Every surface — walls, ceilings, alcoves and columns — is covered in intricate bas-relief sculpture, carved in that same terracotta and depicting scenes from the life of the Buddha across his many rebirths and his journey towards enlightenment. The Jataka tales — the 547 stories of the Buddha’s previous incarnations, in which he appeared variously as a prince, a merchant, a monkey, a deer and countless other forms — are among the most beloved subjects in Thai Buddhist art, and the craftsmen who worked here have rendered them with extraordinary detail and evident devotion. You could spend an hour in here just working your way around the walls, following the narrative from panel to panel, and still not take it all in properly.
Alongside the Buddhist imagery, the interior is also filled with bas-relief sculptures of nagas — the sacred serpents — along with dragons, protective demons and other supernatural guardians drawn from the broader canon of Thai and Hindu mythology. Amongst them, we also spotted sculptures of Hanuman, the monkey-god of Hindu tradition who was absorbed into Thai Buddhist iconography centuries ago and who features prominently in the Ramakien, the Thai national epic based on the Hindu Ramayana. In Thailand, Hanuman is a figure of great strength, loyalty and devotion — the kind of supernatural ally you’d very much want on your side — and his presence here, alongside the nagas and the Buddhist imagery, speaks to the richly layered religious culture that characterises Thai temple art at its best.
🐍 Down the Snake Staircase to the Beach
Having spent a good while wandering around the compound and peering at the bas-reliefs with our noses approximately six inches from the stonework, we made our way to what is arguably the temple’s single most dramatic feature: the staircase that leads directly down from the temple grounds to the rocky shoreline below. And what a staircase it is. The balustrades on either side are formed by enormous sculpted nagas — serpents of truly impressive scale, their bodies rearing up and their heads forming fierce, crowned finials at the top of each flight. The effect, particularly when the light is falling at an angle and throwing the carved scales into sharp relief, is genuinely spectacular, and every single person we saw coming down those steps stopped at some point to take a photograph. We were no exception.
At the bottom of the staircase, the temple grounds give way to a small, rocky beach that feels quite different in character from the manicured white-sand strips of Chaweng and Lamai. This is a working shoreline, with fishing boats and the kind of weathered, salt-bleached atmosphere that reminds you Koh Samui was a working fishing community long before it was a tourist destination — the island only really began to open up to international visitors in the 1980s, when backpackers started arriving from the mainland by boat and found an island of coconut palms, fishing villages and almost no infrastructure whatsoever. Along this stretch of beach we found several smaller shrines and what appeared to be a number of Buddhist tombs — simple, modest structures set close to the water’s edge, the kind of thing you’d walk straight past if you weren’t paying attention, but which add a layer of genuine solemnity to what might otherwise feel like a purely decorative attraction.
🌅 The Perfect Time to Visit
We loved our time at Wat Ratchathammaram, and we’d timed our visit rather well, as it turned out — we arrived in the late afternoon, as the day was beginning to cool and the light was starting its slow, golden shift towards sunset. We’d recommend doing exactly the same if you possibly can. The terracotta of the ubosot is a colour that responds magnificently to warm, directional light: in the flat brightness of midday, it reads as simply red, but as the sun drops towards the horizon and the light takes on that deep amber quality that photographers pursue like bloodhounds, the stonework glows with an intensity that photographs can barely do justice to. The shadows thrown by the bas-relief sculptures become deeper, the carved details pop into sharp relief, and the whole building seems to come alive in a way that it simply doesn’t at other times of day. Worth bearing in mind.

Getting There
Wat Ratchathammaram sits along the southern coast road (Route 4169) in the village of Ban Hua Thanon, and its vivid red exterior makes it easy to spot from the road. From Chaweng, the drive takes around 20 to 25 minutes heading south-west along the coast; from Nathon pier it is roughly 15 minutes heading south-east. The most flexible way to reach it is by rental scooter or car, which allows you to combine the temple with other stops along the southern coast such as the Hin Ta and Hin Yai rocks at Lamai. Grab and private taxis from all main resort areas are a straightforward alternative for those not driving. Shared songthaews run the southern coast road and can drop passengers at Ban Hua Thanon village, though timings are irregular and it is worth confirming the route before setting out.
Getting to and Around Koh Samui
✈️ Getting to Koh Samui by Air
Koh Samui International Airport (USM) is one of Thailand’s more unusual arrival experiences — a boutique open-air terminal tucked into the palm trees on the island’s north-east coast, owned and operated by Bangkok Airways rather than the Thai government. That private ownership shapes everything about flying here: the experience is calm, swift and pleasantly tropical, with immigration and baggage collection typically done in under twenty minutes — but it also means that Bangkok Airways controls which other airlines can serve the island, keeping competition limited and fares higher than on comparable domestic routes.
The great majority of international visitors arrive via Bangkok. Bangkok Airways operates twelve to fifteen daily flights from Suvarnabhumi Airport (BKK), making the connection straightforward, with Thai Airways also offering code-share services on the same route. One-way fares typically range from around THB 3,500 to THB 8,000 depending on the season and how far ahead you book, with December and January commanding the highest prices. There are also a handful of direct international services, including flights from Kuala Lumpur. Book as early as possible to secure the better fares, particularly around Thai public holidays and the weeks surrounding the Full Moon Party on nearby Koh Phangan.

⛴️ Getting to Koh Samui by Ferry and Bus Combination
The budget-conscious alternative to flying is to travel to Koh Samui via Surat Thani on the mainland and take the ferry across. It takes considerably longer than flying — typically three to four hours door to door from Surat Thani — but costs a fraction of the price and is a perfectly comfortable way to arrive, particularly on one of the high-speed catamarans.
Several operators offer combined minivan-and-ferry packages that pick passengers up directly from Surat Thani Airport or the train and bus stations, ferry them to the pier at Donsak, and then cross the Gulf of Thailand to Koh Samui’s Nathon Pier. The main piers on the island are Nathon Pier on the west coast (the main terminal for mainland arrivals), Bangrak Pier (also called Big Buddha Pier) on the north-east coast, and Maenam Pier, which also handles inter-island routes.
Lomprayah High Speed Ferries is the most popular operator, using fast catamarans with air-conditioned cabins and a luggage-loading service — useful for families. Their Surat Thani Airport to Koh Samui packages run from around THB 850 per person and the ferry crossing itself takes approximately one hour to one hour fifteen minutes. In high season and around Full Moon Party dates, Lomprayah ferries can sell out in advance, so booking ahead is strongly advised.
Seatran Ferry and Raja Ferry offer similar combined services, with the conventional Raja car ferries (which can transport vehicles) taking around one hour thirty minutes for the sea crossing from Donsak Pier.

- Booking comparison: 12go.asia | directferries.com
- Fares: From around THB 850–950 per person (foot passenger) for the combined Surat Thani Airport to Koh Samui journey
🚢 Island-Hopping by Ferry (Koh Phangan and Koh Tao)
Koh Samui is the natural jumping-off point for the two other main islands in the Gulf of Thailand, and regular ferries make both an easy addition to any itinerary. Services depart primarily from Bangrak Pier (Big Buddha Pier) and Maenam Pier on the north coast.
To Koh Phangan: Multiple operators run frequent daily crossings, with the fastest high-speed catamarans covering the short hop in around thirty minutes. Lomprayah catamarans run from THB 350 per adult; the slower but charming Haad Rin Queen Ferry charges around THB 200 and can also transport motorbikes. There are around twenty-six daily departures in total across all operators.
To Koh Tao: The crossing takes approximately one hour forty-five minutes by high-speed catamaran. Lomprayah fares start from around THB 700 per adult; standard ferry options run from THB 550. Koh Tao is a world-class diving destination, and most operators include early-morning departures to make the most of a day trip or overnight visit.

🚕 Taxis
Taxis are the most widely used way of getting around Koh Samui and are readily available at the airport, at the main piers, and in the busy beach areas of Chaweng, Lamai, Bophut and Maenam. Unlike taxis in Bangkok, Koh Samui’s cabs do not use meters — fares are fixed per journey and negotiated in advance, so always agree the price before getting in. Rates from the airport vary by destination but typically range from around THB 400 for the short run to Chaweng to THB 800 or more for the southern beaches.
Many tour operators and hotels include pick-up and drop-off in their bookings, which removes the need to arrange a separate taxi for day trips and longer excursions — a useful option to look for when booking activities.
📱 Grab and inDriver (Ride-Hailing Apps)
Grab — Thailand’s equivalent of Uber — operates on Koh Samui and offers a useful alternative to negotiating roadside fares, with prices agreed upfront in the app. It is worth noting, however, that Grab on Koh Samui often works out slightly more expensive than a negotiated taxi fare, and availability can be limited outside the main tourist areas, so it is not always the instant fix it is in Bangkok. Ordering well in advance, particularly for airport transfers, is advisable.
inDriver is a newer ride-hailing alternative on the island that frequently undercuts Grab on price and is worth downloading as a backup option. Note that neither Grab nor inDriver currently operates reliably for pick-up inside Koh Samui Airport itself, so airport arrivals are best handled by the official taxi counter in arrivals.

🛻 Songthaews
A songthaew — the name translates roughly as “two benches” — is a covered pick-up truck with bench seating in the back and a bell or buzzer to signal your stop, and it is Koh Samui’s closest equivalent to a public bus. They run along the main ring road (Route 4169) and some of the major connecting roads, following loose routes rather than rigid timetables, with the driver ultimately deciding where they are headed — always ask before climbing in. Fares for tourists are typically around THB 50–150 per person depending on distance, making songthaews the cheapest way to cover short to medium distances along the ring road. They become less frequent after 8pm and largely disappear after 10pm, so late-night journeys need other arrangements.
Songthaews do not serve the airport, so they are best used for moving between beaches and towns rather than as an arrival or departure option. They can also be chartered privately for a negotiated flat fare, which works out well for small groups wanting to cover the same route as a shared ride.
🚗 Rental Car
Hiring a car gives the most flexibility for exploring Koh Samui independently, and the island’s main ring road — 51 kilometres of mostly flat, well-surfaced tarmac — makes it straightforward to navigate. Rental counters are available at the airport and in the main beach areas, with compact cars typically starting from around THB 1,000–1,500 per day. Driving is on the left, as in the UK.
A valid national driving licence is required, and an International Driving Permit (IDP) is strongly recommended — it is technically required under Thai law and will be expected in the event of a police stop or an insurance claim. IDP applications are available through the AA and the RAC for UK drivers, usually cost around £5.50, and are issued on the same day.

🛵 Scooter and Motorbike Rental
Scooters are the transport of choice for many independent visitors and the most affordable way to cover the island at your own pace, with a standard Honda Click 125cc available from around THB 200–350 per day from rental shops in Chaweng, Lamai and Bophut. Larger automatics such as the Yamaha NMAX run from around THB 350–450 per day.
The same licence requirements apply as for car rental: a valid home driving licence with motorcycle entitlement, plus an IDP with a motorcycle endorsement, are both required under Thai law and expected during routine police checks, which are common on the island. Riding without the correct documentation risks fines, scooter confiscation, and potentially invalidated travel insurance. Always inspect the scooter before setting off and ask the rental shop to share a video of any pre-existing damage — standard practice among reputable operators.
The ring road’s hilly section between Chaweng and Lamai deserves particular care, and riding after dark or in wet conditions is best avoided. Helmets are legally required and available from rental shops; wearing one properly is non-negotiable.
🚲 Bicycle
Bicycle rental is available in the main beach areas and is best suited to leisurely rides within a single neighbourhood rather than tackling the full ring road, where traffic, heat and the hills between Chaweng and Lamai make it a serious undertaking. It is a pleasant option for a morning explore along the flat northern coast around Maenam and Bophut, or for covering the short distances within Chaweng itself.
🗺️ Getting Around — Practical Notes
There is no meaningful public bus network on Koh Samui beyond the songthaews, and the airport has no bus service at all, which makes having a plan for your first transfer more important than on most Thai islands. Arranging an airport or pier transfer with your accommodation in advance is the most stress-free option, particularly for late arrivals or anyone travelling with children and luggage. Pre-booking ferry tickets — especially with Lomprayah in high season — is equally advisable, as sailings can sell out, particularly in the weeks around the Full Moon Party on Koh Phangan.
Vegan Dining in Koh Samui
Koh Samui has become a surprisingly strong destination for plant-based eating, with a growing mix of committed vegan restaurants, wellness cafés and Buddhist Jay buffets spread across the island’s main beach areas.
🌿 Halapua Restaurant
Koh Samui’s most ambitious fully plant-based fine-dining experience, set within the Kapuhala wellness retreat above Bo Phut and dining beside an infinity pool with sweeping sea views. The menu fuses Sicilian cooking with locally grown produce from the on-site farm — think polpette in tomato sauce, layers of parmigiana, and seasonal tasting menus that change with what’s growing. Reservations are essential and the three-course lunch includes pool access until 7 pm.

🍛 Lamai Veggie
A beloved one-woman operation run by Khun Bee — reputedly the first vegan restaurant to open in Lamai, over 15 years ago — serving a daily changing set menu of Thai-inspired plant-based dishes that might include rice, salad, roti, soup, curry and vegan desserts, all made from scratch each morning. Portions are generous, prices are among the most affordable on the island, and the warm, personal service is cited by almost every visitor as the highlight of the experience. A Jay (Buddhist vegan) restaurant in the truest sense.

The menu spans vegan khao soi, mushroom tempura, watermelon salads and a vegan carbonara, with a more refined dinner service as the sun goes down. Non-resort guests are also welcome to dine without a day pass.

🥬 MY Vegan Food Shop & Café
A charmingly unpretentious plant-based café operating from the grounds of Marga Yoga in Taling Ngam, on the quieter western side of the island. The kitchen makes almost everything in-house — vegan cheese, butter and meat alternatives — and serves them in burgers, lasagne, vegan omelettes, cheese boards and “meat” platters alongside a full breakfast menu. Adults-only (no children permitted, in keeping with the yoga centre setting), and tucked away enough that it rewards the drive out.

The Best Time to Visit Thailand
Thailand’s climate is more complex than most, and the single most important thing to understand before planning a trip is that the country has two distinct coastlines — the Andaman Sea to the west and the Gulf of Thailand to the east — which follow opposite monsoon cycles. When the Andaman side is being battered by the south-west monsoon between June and October, the Gulf coast around Koh Samui and Koh Phangan is largely dry. When the north-east monsoon swings in from November, the situation reverses. Bangkok and the north operate on a third rhythm of their own. Getting that geography straight is the key to avoiding a soggy fortnight.
🌞 November to February — Cool & Dry Season
This is Thailand at its most comfortable and, not coincidentally, its most visited. The south-west monsoon has retreated, the north-east monsoon brings dry, cooler air down from China, and the result across most of the country is warm, sunny days with low humidity and pleasantly cool evenings — particularly in Chiang Mai and the northern highlands, where temperatures can drop to 15°C or below overnight in January. The Andaman coast — Phuket, Koh Lanta, the Phi Phi Islands, Krabi — is fully open and at its most inviting, with calm, clear seas ideal for snorkelling and island-hopping. Bangkok is at its most walkable. The trade-off is straightforward: this is also the most expensive and most crowded window of the year, with accommodation on the popular islands booking out months ahead around Christmas and New Year.
Packing: Lightweight breathable clothing for the days, a light layer or thin long-sleeved shirt for cooler northern evenings and air-conditioned transport, swimwear, reef-safe sunscreen, a hat, sandals and a smarter pair of shoes for evenings out.
🌶️ March to May — Hot Season
The coolness of January fades quickly into an often ferocious heat that builds through March, peaks in April and only begins to ease with the first pre-monsoon storms in May. Temperatures in Bangkok regularly hit 38–40°C, the air in Chiang Mai and the north becomes hazy with agricultural burning, and humidity climbs steadily. The saving grace is Songkran, Thailand’s exuberant water festival, which falls in mid-April and turns the streets of every city and town into a good-natured nationwide water fight — one of Southeast Asia’s great travel experiences, and worth timing a trip around specifically. Rates drop noticeably from the December–February peak, and some travellers find the heat manageable provided they plan outdoor activity for early mornings and evenings. By May, the first Andaman resorts begin closing for the low season as the south-west monsoon approaches.
Packing: The lightest, most breathable clothing you own, a refillable water bottle, high-SPF sunscreen, a wide-brimmed hat, sunglasses, and a change of clothes for Songkran if travelling in April — you will get soaked regardless of your plans.
🌧️ June to October — South-West Monsoon
The south-west monsoon arrives in earnest from June, bringing heavy, sustained rainfall to the Andaman coast, the Gulf of Thailand’s western shores and much of the interior. Phuket, Krabi and the Andaman islands receive their heaviest rain of the year, seas turn rough, and several of the smaller island resorts close entirely between June and October. Bangkok floods periodically in September and October, when rainfall peaks. The Gulf coast, however — Koh Samui, Koh Phangan, Koh Tao — follows the opposite pattern and stays comparatively dry through this period, making it the right side of the country to base a beach trip. The north and inland areas receive regular rain but often in short, intense afternoon bursts rather than all-day downpours, and the countryside is extraordinarily lush. Prices across most of Thailand drop to their lowest, and popular destinations feel genuinely quiet.
Packing: Quick-dry clothing, a lightweight waterproof jacket or compact poncho, waterproof sandals, a dry bag for boat trips and electronics, insect repellent, and a flexible itinerary that can bend around weather disruptions.
🌀 November — North-East Monsoon (Gulf Coast)
November sits in a transitional position that deserves separate mention. For most of Thailand, it marks the beginning of the best season — the Andaman coast reopens, Bangkok cools and dries, and Chiang Mai starts to feel wonderful. But the north-east monsoon, which is bringing all that dry, pleasant weather to the rest of the country, simultaneously pushes rain onto the Gulf coast, and Koh Samui and Koh Phangan see some of their heaviest rainfall of the year in November. Flooding can be significant, and a handful of years have seen the Samui airport disrupted. Anyone with the Gulf islands on their itinerary in November would do well to adjust either their timing or their destination.
Packing: Similar to the cool and dry season for most of Thailand — light layers and sun protection — but with a waterproof jacket and a contingency plan if travelling to the Gulf coast.
Overall Best Time
November to February is the easiest answer for most visitors: the weather is at its most reliable, the widest range of destinations is fully accessible, and Thailand in the cool season has a particular lightness to it that is difficult to argue against. For the Andaman coast specifically — Phuket, Krabi, the Phi Phi Islands — December to March is the undisputed prime window. Travellers who want the Gulf islands and can travel outside peak season should target February to April, when the Gulf coast is dry, the Andaman is still perfectly good, and the worst of the heat has not yet arrived. Those happy to follow the sun around the peninsula’s two coastlines, and who plan accordingly, can piece together an excellent trip in virtually any month of the year.
Where to Stay in Koh Samui?
🏖️ Chaweng Beach
Chaweng is Koh Samui’s beating heart — a long, sweeping arc of white sand on the island’s east coast that draws the lion’s share of visitors for good reason. The beach itself is postcard-perfect, lined with sun loungers and fringed by the kind of clear, turquoise water that earns a destination its reputation, while the strip running parallel behind it offers every kind of restaurant, bar, rooftop venue and night market you could want within easy walking distance. It is the liveliest and best-connected base on the island, well suited to first-time visitors who want everything on the doorstep — though those in search of quiet should be aware that Chaweng’s central section can be genuinely noisy after dark, particularly on weekends.
- 🌟 Samui Buri Beach Resort (⭐⭐⭐⭐⭐) — An elegant beachfront retreat with private pool villas, lush tropical gardens and a spa set directly on Chaweng’s quieter northern stretch.
- 🏨 Chaweng Regent Beach Resort (⭐⭐⭐) — A well-regarded mid-range resort with a genuine beachfront position, two pools and a consistently high rating for value and friendliness of staff.
- 🛏️ Chill Inn Chaweng Hostel and Cafe — A clean, well-run hostel a two-minute walk from Chaweng Beach with air-conditioned dorms, a sociable café on site and an 8.6 rating that reflects reliably friendly staff and a prime central location.
🌴 Lamai Beach
Lamai is Koh Samui’s second-largest beach and, for many visitors, the more appealing alternative to Chaweng — wide, handsome and backed by a strip of restaurants, bars and shops that is lively enough to keep things interesting without ever quite tipping into the frenetic energy of its northern neighbour. The beach itself has a slightly rockier character at its southern end, where the famous Grandfather and Grandmother Rocks draw a steady stream of curious visitors, but the central and northern stretches offer some of the cleanest, least crowded sand on the island. It is a particularly good base for families and couples who want proximity to facilities without committing fully to Chaweng’s party scene.
- 🌟 Banyan Tree Samui (⭐⭐⭐⭐⭐) — One of the island’s most celebrated luxury resorts, with private infinity-pool villas perched above a secluded stretch of Lamai Bay, a world-class spa and a 9.4 rating built on exceptional staff and meticulous attention to detail.
- 🏨 OUTRIGGER Koh Samui Beach Resort (⭐⭐⭐⭐⭐) — A handsome colonial-style resort sitting directly on Lamai Beach with two pools, a swim-up bar, a children’s club and a reputation for particularly warm and helpful staff at a price point well below the island’s top-tier luxury properties.
- 🛏️ The Rock Samui Poshtel Lamai Beach — A cut above a standard hostel, with an infinity pool, private beach area and a mix of dorms and private rooms that earns it a devoted following among solo travellers and couples seeking good value on the quieter southern edge of Lamai.
🌺 Bophut (Fisherman’s Village)
Bophut sits on the island’s quieter north coast and centres on Fisherman’s Village, a preserved stretch of old Chinese shophouses turned boutique galleries, independent restaurants and atmospheric bars that gives this corner of Koh Samui a character entirely its own. The beach here is narrower and calmer than Chaweng or Lamai — more paddling than surfing — but the trade-off is a genuinely unhurried pace, excellent seafood and one of the island’s best weekly markets, the Fisherman’s Village Walking Street, which takes over the main road every Friday evening. It is the natural choice for travellers who prefer charm and character over facilities and nightlife, and it suits couples and repeat visitors particularly well.
- 🌟 Anantara Bophut Koh Samui Resort (⭐⭐⭐⭐⭐) — A refined five-star retreat set directly on Bophut Beach within walking distance of Fisherman’s Village, with beautifully landscaped tropical gardens, a large beachfront pool and the kind of seamless, warm service that earns it consistently outstanding guest scores.
- 🏨 ibis Samui Bophut (⭐⭐⭐) — A reliable, beach-adjacent three-star option positioned directly beside the sand in a quiet location, with modern rooms, a pool, a restaurant and over 2,000 reviews that reflect solid value and friendly staff.
- 🛏️ HOST’S EL Fisherman — A bright, well-maintained hostel a five-minute walk from Bophut Beach and a short stroll from Fisherman’s Village, praised by guests for its spotless facilities, welcoming atmosphere and genuinely helpful hosts.
🌊 Mae Nam
Mae Nam is the least-developed of Koh Samui’s main beach areas, stretching along a long, gently curving bay on the north coast that catches cool breezes off the Gulf of Thailand and sees a fraction of the crowds that descend on Chaweng or even Bophut just along the road. The beach is wide, shaded by casuarina trees and ideal for a morning run or an undisturbed afternoon with a book, and the small village behind it offers enough in the way of local restaurants, massage shops and minimarkets to be self-contained without feeling overly touristy. It is the right base for visitors who genuinely want to slow down, and it has a particular following among long-stay travellers and families with young children.
- 🌟 Santiburi Koh Samui (⭐⭐⭐⭐⭐) — A long-established luxury resort set within extensive, manicured grounds on Mae Nam Beach, with a championship golf course, a full-service spa, a huge beachfront pool and a 9.1 rating underpinned by superb breakfasts and attentive personal service.
- 🏨 Fair House Villas & Spa (⭐⭐⭐⭐) — A tranquil beachfront resort with spacious, individually furnished villas, a private beach, a pool and an 8.8 guest score that consistently highlights the exceptional staff and the peaceful setting well away from the island’s busier tourist areas.
- 🛏️ Blockhouse Samui — A relaxed, community-spirited hostel run by a warmly welcoming host a short walk from Mae Nam Beach, with an excellent on-site Thai kitchen, clean private rooms and dorms, and an 8.9 rating driven by one of the friendliest atmospheres on the island.
🛥️ Choeng Mon
Choeng Mon occupies the island’s north-eastern tip, a compact, sheltered bay with a small but perfectly formed beach that feels considerably more exclusive than its relatively modest size might suggest. The water here is consistently calm and clear, the beach is rarely crowded even at peak season, and the small cluster of upscale resorts and restaurants that surround it give Choeng Mon something of a private-island feel despite being less than twenty minutes from Chaweng by road. It is a natural choice for honeymooners and couples after a more secluded experience, and its position makes it easy to combine the tranquillity of Choeng Mon with day trips to Chaweng or Big Buddha when the mood for something livelier strikes.
- 🌟 The Ritz-Carlton, Koh Samui (⭐⭐⭐⭐⭐) — Set across 58 acres of Choeng Mon headland, this flagship luxury resort combines clifftop pool villas with a private beach, a hilltop bar and a level of service consistent with the brand’s global reputation, rated 8.8 by guests on Booking.com.
- 🏨 SALA Samui Choengmon Beach Resort (⭐⭐⭐⭐⭐) — A boutique-luxury property with an 80-metre private beach, two beachfront pools, outdoor-bathroom villas and a 9.4 guest score — one of the highest on the island — that reflects exceptional food, flawless service and a genuinely intimate atmosphere.
- 🛏️ Hi Samui Hostel — A freshly renovated hostel a three-minute walk from Choeng Mon Beach with clean dorms and private rooms, a bar, on-site restaurant and a lively but laid-back atmosphere that makes it the obvious budget choice in this otherwise upscale corner of the island.
