Kinabalu Park established as one of the first national parks of Malaysia in 1964, is Malaysia's first World Heritage Site designated by UNESCO in December 2000 for its "outstanding universal values" and the role as one of the most important biological sites in the world.
Malaysia: Borneo (Sabah) – Cruising the Kinabatangan River
🚤 Heading Upriver to Kinabatangan
We made our way to Sandakan that morning, which sits on the north-east coast of Malaysian Borneo and has had, it’s fair to say, a rather eventful history. The town was once the capital of British North Borneo, declared so back in 1884, and was razed almost completely to the ground by Allied bombing during the Second World War — the Japanese had been using it as a base. It’s been rebuilt since, obviously, though it’s not exactly what you’d call a showpiece destination. Still, it served its purpose: we were here to catch a boat to the Kinabatangan river.
Our base for the next couple of days was the Kinabatangan Wetlands Resort (KWR), roughly a 2-hour boat ride from Sandakan along one of the longest rivers in Malaysia — the Kinabatangan stretches some 560 kilometres through the interior of Sabah. The river and its surrounding floodplain make up one of only two regions in the world where you can find ten primate species living alongside each other, which is either remarkable or deeply unsettling depending on your feelings about primates. Either way, we were headed straight into the middle of it.
The first section of the journey took us out through the estuary and onto the open South China Sea. Now, I’m not a great sailor at the best of times, and this was emphatically not the best of times. The boat had a fair lick of speed, which sounds marvellous until you realise the water was quite choppy once we’d left the shelter of the river mouth. The hull was slapping the waves with the kind of enthusiasm I usually reserve for a bacon sandwich. Bumpy is one word for it. Teeth-rattling might be more accurate.
After an hour or so, we turned off the open sea and entered the broad mouth of the Kinabatangan itself. The water settled almost immediately, and with it, so did my nerves — and my stomach. The river here is wide and slow-moving, lined on both sides by dense lowland rainforest that has been doing its thing largely undisturbed for millions of years. Almost immediately we started seeing wildlife, mostly birds at this early stage. The most abundant by a considerable margin was the white stork — or more precisely what’s known locally as the Storm’s stork, a large and rather imperious-looking bird that stands around a metre tall and clearly knows it. They were perched along the riverbanks as if they’d been placed there specifically for our benefit, which was decent of them.
We rolled up to the KWR just as lunch was winding down, which was either good timing or terrible timing depending on how you look at it — good because there was still food, terrible because there was still food and we were absolutely famished. It was a buffet, which in our current state was frankly dangerous. We tucked in with considerably more enthusiasm than dignity.
Our room wasn’t quite ready, as the previous guests were apparently in no particular hurry to vacate. Some people have no shame. So we lingered in the lodge, which turned out to be no hardship whatsoever. The KWR lodge is a raised wooden structure built right on the edge of the riverbank, open-sided and breezy, with views straight into the jungle. I didn’t even have to move from my chair to find wildlife. I simply leaned over the railing and there, in the gloriously squelchy mud directly below, was a family of Bearded Pigs — Sus barbatus, since you ask — going about their afternoon business with tremendous commitment. Rooting, wallowing, thoroughly enjoying themselves. Completely unbothered by us lot gawping from above. Honestly, I knew exactly how they felt after that buffet.
Our room was eventually ready, and we had just enough time to dump our bags, grab a quick cup of tea, and head straight back out for an afternoon river trip — the Kinabatangan waits for no one, apparently.
The KWR lives up to its name. The entire resort sits on stilts above the wetlands, connected by a series of wooden boardwalks that wind their way between the lodges and the main buildings. I should mention at this point that those boardwalks and I were destined to have something of a falling out — quite literally — but I’ll come to that sorry episode another time.
The resort has ten private lodges dotted along the riverbank, and ours turned out to be the very last one, a fair old trek from the main reception, restaurant and general hub of civilisation. Not ideal at six in the morning, but we’ll gloss over that.
The room itself, however, was a very pleasant surprise. It was enormous — the sort of size that makes you wonder what you’ve done right for once. A ginormous bed, a king-sized bathroom, and best of all, an outdoor shower tucked away on a private deck. We were rather looking forward to the next couple of nights.
Late afternoon on the Kinabatangan means one thing: time to get back on the water. The plan was a river cruise during that golden window just before dusk, which is apparently when the monkeys head down to the riverbanks to roost for the night. We joined our six fellow explorers and a couple of guides on a much smaller boat than the one that had delivered us here — a narrow, open vessel that sat reassuringly close to the waterline — and followed the channel out onto the main river.
It wasn’t long before we spotted our first troop of proboscis monkeys. These are extraordinary creatures, found only in Borneo, and the dominant males sport an enormous pendulous nose that hangs down over their mouths like a deflated party balloon. Think Gonzo from the Muppets, but with better table manners. Probably. They were leaping athletically between the branches overhanging the water, which was both thrilling and slightly showing off. As we pushed further downriver, we came across more troops — long-tailed and pig-tailed macaques, and the elegant silver and maroon langurs, also known as red leaf monkeys, their rust-coloured fur catching the last of the fading light. Watching them settle into the trees for the night felt genuinely privileged. These animals have been going about their evening routines along this river for thousands of years, entirely indifferent to the boatload of wide-eyed tourists gawping at them from below.
The birds kept up their end of the bargain too — more storks, naturally, plus brilliantly coloured kingfishers darting low across the water like small electrified jewels.
Then, just as we were turning to head back to KWR, we noticed several other boats moored up ahead along the bank. Any seasoned wildlife watcher knows that cluster of stationary vessels means only one thing. Sure enough, moving through the dense jungle not twenty metres from the water’s edge was a small herd of Bornean pygmy elephants. We nearly lost our minds. Pygmy elephants are a distinct subspecies, recognised only in 2003, and are found almost exclusively along the Kinabatangan floodplain. They’re smaller than their Asian cousins, rounder in the face, and rather endearing — though you’d be a fool to get too close. The forest was thick and the light was going fast, but we could make them out clearly enough as they moved through the undergrowth. Quite remarkable.
Then reality reasserted itself, as it tends to. Night was falling with the speed and commitment that only the tropics can manage — one minute there’s a genuinely spectacular sunset smeared across the sky, the next it’s absolutely pitch black. No ambient city glow out here. Nothing. And then the boat driver discovered his lamp wasn’t working. He borrowed a small torch from one of the guides. A small torch. For navigating a jungle river in the dark. With a thunderstorm building ominously on the horizon. Our guides waved vaguely at the sky and said “no worries,” which is exactly what you say when there are, in fact, worries.
The river is wide, but it carries plenty of floating debris — logs, branches, the kind of things that end a journey abruptly — and our driver showed no particular interest in slowing down. My main concern, beyond immediate capsize, was the inlet back to KWR: a narrow gap of perhaps twenty feet cut into the forest wall, completely invisible in the darkness. How on earth he was going to find it was beyond me.
He found it. First time. We pulled in, tied up, and climbed out onto solid ground with the collective relief of people who had very much underestimated their own anxiety. Brilliant evening, all told.
In summary …
- We highly recommend taking a trip from Sandakan out to the Kinabatangan River and spending a few days exploring the river and the rainforest.
- The proboscis monkeys, orangutans and if you are lucky Bornean pygmy elephants are amazing.
- This is a remote location so there is no popping out to the shops, so you’ll be at your resort or on the river – unless you get to explore one of the villages.
Best time to visit Sabah, Borneo
🌞 Dry Season — March to October (Peak Time)
For the majority of travellers, the dry season represents the most appealing window to visit Malaysian Borneo. From approximately March through to October, both Sabah and Sarawak enjoy relatively lower rainfall, calmer seas, and longer stretches of sunny weather. This is when the region truly comes into its own.
In Sabah, this period is ideal for climbing Mount Kinabalu, as cloud cover is thinner in the early morning and summit views are far clearer. Diving and snorkelling around the islands of Sipadan, Mabul, and Lankayan reach peak conditions between April and September, when visibility underwater can exceed 30 metres. Turtle nesting and hatching activity at Turtle Islands Park is also at its most reliable during these months. Wildlife watching in the Kinabatangan River corridor is excellent, as lower water levels concentrate animals along the riverbanks, making orangutan, pygmy elephant, and proboscis monkey sightings more predictable.
In Sarawak, the dry season opens up the national parks in full. Trekking in Gunung Mulu National Park becomes far more manageable, with trail conditions at their best. Longhouse visits along the Rejang and Skrang rivers are more easily arranged, and boat journeys on these rivers are safer and more comfortable. The famous Rainforest World Music Festival, held annually in Kuching in July, falls squarely within this window and draws visitors from across the globe.
The months of July and August represent the absolute peak of tourist activity. Accommodation books up quickly, particularly around Sipadan (which operates a strict daily permit quota) and in Kota Kinabalu. Booking several months in advance is strongly advised for this period.
What to pack: Lightweight, breathable clothing in moisture-wicking fabrics, a light waterproof jacket for afternoon showers, UV-protective swimwear and a rash vest for snorkelling and diving, high-factor reef-safe sunscreen, insect repellent containing DEET, sturdy waterproof trekking boots with ankle support, a dry bag for river and boat excursions, a compact head torch for early-morning wildlife walks, and electrolyte tablets for hydration on mountain hikes.
🌧️ North-East Monsoon — November to February (Wet Season, East Coast)
The north-east monsoon sweeps in from the South China Sea between November and February, bringing heavy and sustained rainfall primarily to the east coast of Sabah and to much of Sarawak. This is considered the low season, and while the weather presents genuine challenges, it also carries its own rewards for the flexible traveller.
On Sabah’s east coast — including the Semporna Archipelago and Sandakan — seas can be rough and dive operators frequently suspend trips to the outer islands. Sipadan permits become easier to obtain, and accommodation prices drop noticeably. However, many dive resorts and liveaboards close entirely during the worst weeks of November and December, so confirming operations in advance is essential.
Inland and at elevation, the wet season actually keeps the rainforest lush and extraordinarily alive. The Danum Valley and Maliau Basin — among Borneo’s most pristine wilderness areas — remain accessible, and the reduced visitor numbers lend the experience a particular intimacy. Leech socks become non-negotiable in the forest during these wetter months, but wildlife encounters can be just as rewarding.
Kota Kinabalu itself, on Sabah’s west coast, is somewhat sheltered from the north-east monsoon and remains a viable base throughout this period. The city’s restaurants, night markets, and cultural attractions are enjoyable regardless of season.
In Sarawak, Kuching receives increased rainfall but functions well as a city destination. The Sarawak Museum and its annexes, the waterfront, and the Semenggoh Wildlife Centre (home to semi-wild orangutans) all operate year-round. The Bako National Park, accessible by boat from Kuching, remains open and offers some of the best proboscis monkey viewing in the world even during the wet season.
Chinese New Year, which falls in January or February depending on the lunar calendar, brings vibrant celebrations to Kuching, Kota Kinabalu, and Sibu. The atmosphere is festive and colourful, though some businesses close for several days around the main holiday.
What to pack: Quick-dry clothing and trousers, a high-quality waterproof poncho or rain jacket (not merely water-resistant), sealed waterproof bags for electronics, leech-proof socks and gaiters for jungle trekking, sandals that dry rapidly for wet conditions, a compact microfibre towel, anti-fungal foot powder, a portable umbrella, and a small first-aid kit with blister treatment.
🌊 South-West Monsoon — May to September (West Coast Wet, East Coast Dry)
The south-west monsoon, though generally gentler than its north-eastern counterpart, brings increased rainfall to the west coast of Sabah and to Sarawak’s interior from roughly May through to September. Importantly, this coincides with the dry season on the east coast, which is why the Sipadan diving season peaks during these very same months — the south-west monsoon barely affects the Celebes Sea.
For travellers focused on Kuching and Sarawak’s national parks, May through August can bring occasional heavy downpours in the afternoons, but mornings are frequently clear, and the overall conditions remain manageable for most activities. The Iban longhouses along Sarawak’s rivers are at their most welcoming during the Gawai Dayak harvest festival, celebrated on 1st and 2nd June each year. This is one of the most culturally immersive experiences Malaysian Borneo offers, and visitors fortunate enough to be invited to participate in the celebrations gain a rare insight into indigenous Dayak culture.
Trekking conditions in Mulu during this window are firm underfoot, and the cave systems — including Deer Cave and Lang’s Cave — are operational throughout the year.
What to pack: Lightweight long-sleeved shirts for sun and insect protection, a compact but packable rain jacket, sandal-style trekking footwear for river crossings, reef-safe sunscreen and a wide-brimmed hat, a reusable water bottle with a filtration element, cultural gifts (such as small quality sweets or craft items) if visiting longhouses, a small padlock for guesthouse lockers, and anti-malarial medication if advised by your GP or travel clinic.
🌡️ Year-Round Considerations
Regardless of when you visit, certain conditions are constant in Malaysian Borneo. The heat and humidity are ever-present, making physical acclimatisation important on the first day or two. At altitude — particularly above 3,000 metres on Mount Kinabalu — temperatures can drop sharply at night, and thermal layers are necessary even in the driest months. Jellyfish blooms can affect coastal swimming at any time of year, so asking local advice before entering the sea is always prudent. Leeches are present in the forest year-round, increasing significantly after rainfall.
📋 Season Summary Table
🧳 Overall Best Time to Visit
If you can visit only once, the months of April, May, and early June represent the finest all-round window for Malaysian Borneo. The dry season is well established on the east coast, bringing excellent diving conditions around Sipadan and reliable wildlife watching along the Kinabatangan. Inland trekking in Danum Valley, Mulu, and on Mount Kinabalu is at its best, with manageable trails and lower risk of summit cloud. Crowds have not yet reached the intensity of July and August, meaning accommodation is easier to secure and permit queues are shorter. The heat is significant but no more extreme than any other month, and the landscape — fed by months of previous rain — is a deep, saturated green. Travellers with a particular interest in Sarawak’s indigenous festivals should target late May into early June to coincide with Gawai Dayak, an experience that elevates any trip to the region from memorable to genuinely transformative.
Where to stay?
1. Kinabatangan Wetlands Resort
Deep in the heart of Malaysian Borneo, Kinabatangan Wetlands Resort is a hidden gem that rewards those willing to venture off the beaten track. Nestled within the Lower Kinabatangan-Segama Wetlands — a RAMSAR-designated conservation area and the largest of its kind in Malaysia — the resort offers an immersive escape into one of the world’s most biodiverse ecosystems. Accessible only by boat, it’s a fantastic choice for intrepid travellers seeking comfort without sacrificing wilderness. Ten tastefully designed twin cabins sit among the trees, featuring dark wooden floors, white linens, and locally-made fabrics, with solar-powered fans and en suite facilities rounding out the comforts. Guests can look forward to boat safaris spotting proboscis monkeys, hornbills, and more, plus delicious buffet meals and spacious cabins with sweeping forest views — a truly unforgettable Bornean adventure.
2. Nature Lodge Kinabatangan
Perched on the banks of the legendary Kinabatangan River in Sabah, Malaysian Borneo, the Nature Lodge Kinabatangan — now operating as Tanini Kinabatangan — is the kind of place that reminds you why you travel. The lower Kinabatangan is one of Sabah’s most splendid natural treasures and boasts the richest concentration of wildlife in Southeast Asia, and this intimate eco-lodge puts you right in the heart of it. Spend your days cruising the river in search of wildlife, or post up at the lodge’s three-story solar viewing tower. Guides here are passionate and knowledgeable, regularly helping guests tick off all five of Borneo’s “Big Five” — including orangutans and Bornean pygmy elephants. Rustic, warm, and genuinely green, it’s an experience that stays with you long after you leave the jungle behind.
3. Sakau Rainforest Lodge
Tucked along the banks of the Kinabatangan River in Malaysian Borneo, Sukau Rainforest Lodge is one of Southeast Asia’s most extraordinary eco-retreats. Named one of National Geographic’s Unique Lodges of the World, it strikes a rare balance between comfort and conscience. Built in 1995 as the first lodge in the area, it was designed from the outset according to the principles of ecotourism, and that ethos still runs through everything it does. Raised walkways connect a collection of rooms crafted from local hardwood, where natural light streams through the windows and ceiling fans run on solar power. Outside your door, wildlife thrives: all seven species of Bornean primates, orangutans in their natural habitat, and herds of Borneo pygmy elephants are regularly spotted along the river. Whether you’re here for the wildlife, the jungle stillness, or simply to unplug in one of the world’s last great rainforests, Sukau delivers something genuinely unforgettable
