Malaysia: Borneo (Sabah) – Sepilok Orangutan Sanctuary
🦧 A Long-Overdue Date with an Orangutan
I have had a love affair with orangutans for as long as I can remember. Don’t ask me why — I can’t entirely explain it myself. There’s just something about those great, ginger, contemplative faces that got under my skin somewhere along the way, and it never quite left. So a trip to Borneo had been sitting on my bucket list for years, gathering dust alongside “learn Portuguese” and “get better at parallel parking.” Neither of those happened either, but Borneo did.
The thing that finally got me off the sofa and onto a very long series of aeroplanes was a growing sense of urgency. The rainforests of Borneo are disappearing at a rate that would make your eyes water, and I felt strongly that if I was going to see this place properly — meaning the real, wild, ancient, dripping-wet version of it — I needed to stop faffing about and actually go. A staggering 50% of all tropical timber procurement worldwide comes from Borneo. Half. That’s not a statistic you can just file away and forget. On top of that, palm oil plantations have been spreading across the island like a rash, with vast tracts of primary rainforest being bulldozed flat to make room for the stuff. Palm oil, as you may know, turns up in everything from biscuits to shampoo to margarine, and the demand for it has been absolutely relentless. The result is that Borneo’s ancient forests, some of the oldest and most biodiverse on the planet — we’re talking 130 million years old, which makes the Amazon look like a newcomer — have been shrinking at an alarming pace. I didn’t want to arrive and find I’d missed the point entirely.
🌏 The Island Itself — Bigger Than You Think
Borneo is the third largest island in the world. Not third largest country, not third largest landmass — third largest island, which puts it in some rather distinguished company, behind only Greenland and New Guinea. It covers roughly 743,000 square kilometres, which, since we’re British and still quietly confused by metric, is about the size of Texas, or if you prefer, approximately ten United Kingdoms stacked together rather untidily.
What makes Borneo politically interesting — and slightly baffling at first glance — is that it is divided between three entirely separate sovereign entities. Indonesia controls the lion’s share, roughly 73% of the landmass, in the form of the provinces collectively known as Kalimantan, a name derived from the old Malay word Kalamanthana, meaning something along the lines of “burning weather island,” which does rather tell you something useful about what to pack. Malaysia accounts for about 26%, made up of the states of Sabah and Sarawak on the northern and north-western coast — both of which joined the Malaysian federation in 1963 when it was formed, a process that was, diplomatically speaking, not entirely without drama. And then there is Brunei, tucked into the north coast like a small, oil-rich afterthought, occupying a mere 1% of the island but punching considerably above its weight in terms of per capita wealth. Brunei has been a sovereign sultanate since the 15th century, when it was actually a rather powerful regional force, and it became a British protectorate in 1888, finally gaining full independence in 1984. The Sultan, for what it’s worth, is one of the wealthiest individuals on earth. One percent of the island; not a bad slice.
Geographically, Borneo straddles the equator almost perfectly, sitting roughly half in the northern hemisphere and half in the southern, which means it gets an extremely efficient soaking from both monsoon seasons and is essentially wet one way or another for most of the year. We found this out fairly promptly.
Around 21 million people call Borneo home, spread across its three jurisdictions, and they represent a genuinely extraordinary mix of ethnicities, languages and cultures. The indigenous Dayak peoples — a broad collective term covering dozens of distinct groups, including the Iban, the Kadazan-Dusun, the Kenyah, the Kayan and many others — have been living in the island’s interior for thousands of years, and their traditions, longhouse architecture and relationship with the forest are something else entirely. But we’ll get to all of that.


🦧 Sandakan, Sepilok and the Orangutan Who Tried on a T-Shirt
I am not sure the English language has quite the right words for how excited I was when we finally touched down at Sandakan. Sandakan sits in the north-east corner of Sabah, which is Malaysia’s slice of Borneo, and it has had a fairly eventful history for a place that most people couldn’t find on a map without a good ten minutes of squinting. It was the original capital of British North Borneo in the late 19th century, a prosperous timber and trading port, until the Japanese occupation during the Second World War left it almost entirely destroyed. The post-war rebuilding gave it a rather functional, no-nonsense look that it has largely kept ever since. It is not a glamorous city. But it is the gateway to some of the most extraordinary wildlife on earth, so we forgave it immediately.
The airport is tiny — a handful of flights a day, a modest terminal, the sort of place where you half expect someone’s auntie to be behind the check-in desk. And yet, despite its modesty, it managed to take an absolute age for our bags to appear. The reason, we suspect, was that our flight in from Kuala Lumpur had been packed with local passengers returning home laden with an impressive quantity of shopping. We are talking serious cargo here — cardboard boxes of every conceivable size, rolls of paper, what appeared to be at least one ceiling fan. Getting all of that off a plane and onto a single baggage belt is, it turns out, something of a logistical undertaking. We waited. We waited some more. Eventually, the bags arrived, and we made our way out into the thick, wet Bornean air.
From the airport we transferred to what would be our base for the next couple of days: the Sepilok Jungle Resort, which sits right next door to the orangutan sanctuary — and we mean right next door, as in the jungle that contains wild orangutans begins essentially at the edge of the garden. If you are planning time in Sepilok to see the orangutans, we would recommend this place without hesitation. More on that shortly.
We were still feeling the full effects of the journey that first morning, but jet lag, it turns out, is no match for the Bornean dawn chorus, and we were up at an unreasonable hour regardless. We had been told an orangutan had nested close by the previous night, so we headed out hopefully into the early morning half-light. Sadly, he or she had already gone about their business by the time we got there. Instead, we walked the boardwalks that wind around the resort, which turned out to be no consolation prize whatsoever. At that hour, the forest was in the middle of what you might call a changing of the guard — the nocturnal shift clocking off, the daytime crew clocking on — and the birdlife alone was staggering. Hornbills, kingfishers, things we couldn’t name but stared at for far too long. All of this within the narrow confines of the resort grounds. Not bad before breakfast.
After we ate, we were making our way back to our room when one of the staff started waving at us with some urgency, beckoning us to follow her. We were just in time to see an orangutan strolling along the boardwalk with the unhurried confidence of someone who owns the place — which, in fairness, is a reasonable position for an orangutan to take — before melting calmly into the jungle. As we walked back, Karen got chatting to another guest who had her own encounter to report. Apparently, this same orangutan had earlier turned up on the deck of her chalet and, in what we can only describe as a bold lifestyle choice, had attempted to try on her husband’s t-shirt. When the guest appeared, the orangutan bared its teeth, which is not the sort of thing you want to see on an animal that is considerably stronger than you. She was, understandably, spooked. We were, equally understandably, absolutely delighted by the story.
Our first proper visit of the day was to the Sepilok Orangutan Rehabilitation Centre, which is the whole reason most people make it to this corner of Borneo in the first place. The centre was founded in 1964 by a British woman named Barbara Harrisson, working under the Sabah Forest Department, at a time when habitat destruction and hunting were already taking a serious toll on orangutan populations. The site covers 43 square kilometres of protected land on the edge of the Kabili-Sepilok Forest Reserve, and today somewhere between 60 and 80 orangutans live freely within it.
Orangutans, we should say, are remarkable animals in ways that go well beyond their habit of borrowing clothing. They spend most of their lives high up in the forest canopy, rarely coming down to ground level. The name itself tells you everything — orangutan comes from the Malay words orang, meaning person, and hutan, meaning forest. Man of the forest. It is thought the name came from indigenous peoples who observed the older, larger apes moving slowly through the undergrowth below the canopy, and drew what seemed like a reasonable conclusion. Younger orangutans are almost entirely arboreal; it is only as they age and grow heavier that they begin to spend more time at ground level, which incidentally makes them more vulnerable to hunters and to the advancing edge of farmland.
Most of the orangutans that pass through Sepilok arrive as orphans. Their mothers have typically been killed — by hunters, by farmers protecting crops, or by logging operations clearing the forest. The centre has processed around 740 orangutans since it opened, and a significant number of those have been successfully returned to the wild, either within the Kabili-Sepilok reserve itself or at release sites elsewhere across Sabah. The process of rehabilitation takes years. These are highly intelligent animals that would normally spend the first seven or eight years of their lives learning survival skills from their mothers, and replicating that education in a rescue setting is painstaking work. The centre is officially administered by the Sabah Wildlife Department, which provides some funding, though the bulk of financial support comes from visitor fees and from the Orangutan Appeal UK, a British charity that has been supporting the centre for decades.
The centre is open year-round, and the peak times to visit are the twice-daily feeding sessions at the platforms — 10 in the morning and 3 in the afternoon. There are two platforms. The first is in the nursery observation area, where younger orangutans are brought out under supervision. The second is deeper into the reserve, visited by orangutans that have already been released back to semi-wild life, and sometimes by other local primates who have worked out that free food is free food — pig-tailed and long-tailed macaques being the main opportunists.
Watching the orangutans swing through the trees above the feeding platforms, moving with a fluid, effortless grace that made the whole thing look entirely too easy, was one of those experiences that is genuinely difficult to put into adequate words. We have tried, and this is what we came up with. It was, quite simply, wonderful.
In Summary …
- A visit to the Orangutan Rehabilitation Centre is a must – they are amazing creatures
- The Centre gets very busy at the time when the food is put out on the feeding platforms – but this is the best time to see the orangutans.
- Consider sponsoring an orangutan at the Rehabilitation Centre – they are struggling to survive in the wild due to conflict with humans

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. Sepilok B&B
Nestled the rainforest edges of Sabah, Malaysian Borneo, Sepilok B&B has been welcoming budget-savvy wildlife lovers since 2006. Steps from the Rainforest Discovery Centre and just a short drive from the Borneo Sun Bear Conservation Centre, it’s hard to beat the location — you wake up to birdsong and fresh air, with the famous Sepilok Orangutan Rehabilitation Centre practically on your doorstep. Rooms range from family chalets with balconies and garden views to more basic options, all keeping things affordable without sacrificing comfort. A complimentary local breakfast is served each morning, the on-site café is praised for its affordability, and staff are consistently described as friendly and full of local knowledge. It’s the kind of no-fuss base camp that wildlife enthusiasts dream about.
2. Nature Lodge Sepilok
Tucked into the lush edges of the Kabili-Sepilok Forest Reserve in Sabah, Borneo, Sepilok Nature Lodge is a tranquil hideaway in a forest clearing, tastefully styled with bungalows dotted around dense foliage, boardwalks, and lakes. All 23 chalets feature verandas with beautiful lake or jungle views, and the resort’s main building — housing the restaurant — is built with a traditional wooden interior that reflects its natural surroundings. The beautifully landscaped gardens boast a remarkable collection of more than 150 different Asian orchid varieties. Best of all for wildlife enthusiasts, the lodge is just a five-minute walk from the famous Sepilok Orangutan Rehabilitation Center — meaning you might just wake up to an orangutan swinging through the trees outside your veranda. It’s the kind of place that makes you slow down, breathe in the rainforest air, and never want to leave.

3. Sepilok Jungle Resort
During our visit to Sepilok, we stayed at the Sepilok Jungle Resort, enclosed inside a tropical virgin rainforest, adjacent to the world-famous Sepilok Orangutan Sanctuary. In fact, wild orangutans were visiting the Resort during our stay – we even saw one early in the morning walking around the boardwalks and apparently taking things from people’s balconies.
The rooms were basic but comfortable. The breakfasts were fine and they accommodated us being vegan. We also had an evening meal there which was traditional Malaysian fare – very tasty. The whole place is surrounded by rainforest, which is spectacular. In the evenings they run a night safari that goes out into the rainforest, which is a very noisy place at night with all the nocturnal creatures coming to life. We got to see some interesting bugs and birds on our adventure, including leeches … yuk!
In the evenings, they run a night safari that goes out into the rainforest, which is a very noisy place at night with all the nocturnal creatures coming to life.
The walk itself started close to the main lodge. Being in a rainforest means that the area gets more than its fair share of rain, so they have wellington boots you can borrow (I am a US size 13 … which proved to be challenging) as well as some very poor flashlights (or torches as our fellow Brits would say). As we waited for our group to gather we had a very unexpected treat, a young orangutan decided to build its nest in the tree right above our heads. We were told the attraction of this particular tree was its fruits, which were now fully ripe. It is obvious that orangutans don’t have any natural threats (apart from man) as they make one hell of a racket whilst building their bed for the night.
By the time we set off, it was pitch black. The dense jungle means that there is no natural light, so having flashlights with you is pretty much essential. The thing that really hits you the most is not the darkness but how really noisy the jungle is at night – there is a true cacophony of sounds emanating from all directions. If you are a light sleeper forget about having a good nights rest! During the tour, we got to see insects (pill millipedes and stick insects), invertebrates (leeches!), frogs and some small roosting tailorbirds.
At the end of the tour we did a leech check, and much to her horror Karen had two latched to her. One was on her jacket, and the other had managed to work its way onto her cleavage – I thought this was hilarious … she didn’t quite see the funny side.
