The best things to see in Borneo include orangutans at Sepilok and Tanjung Puting, wildlife along the Kinabatangan River, the ancient rainforest of Danum Valley, Mount Kinabalu, Gunung Mulu’s enormous caves, Sarawak’s Bako National Park, and the tropical waters around Sabah. Yet Borneo is too large and varied to experience through wildlife alone: longhouses, Indigenous cultures, river journeys, rainforest trekking, caves, beaches, diving, and food all deserve space in a well-planned trip.
Borneo is also not a country. The island is divided among Malaysia, Indonesia, and Brunei, with the Indonesian portion known as Kalimantan and the Malaysian states of Sabah and Sarawak occupying the north.
For a first visit, Sabah and Sarawak provide some of the easiest combinations of wildlife and landscapes. Travelers with additional time can venture into Kalimantan for river journeys, Dayak culture, and destinations such as Tanjung Puting National Park.
Here’s where to focus when deciding what to see in Borneo.

| Place | Region | Main Highlight |
| Sepilok | Sabah, Malaysia | Orangutan rehabilitation |
| Kinabatangan River | Sabah, Malaysia | River wildlife safaris |
| Danum Valley | Sabah, Malaysia | Primary rainforest |
| Kinabalu Park | Sabah, Malaysia | Mount Kinabalu and biodiversity |
| Kota Kinabalu | Sabah, Malaysia | City, islands, food |
| Sipadan region | Sabah, Malaysia | Diving |
| Kuching | Sarawak, Malaysia | Culture, food, regional base |
| Bako National Park | Sarawak, Malaysia | Proboscis monkeys and hiking |
| Semenggoh | Sarawak, Malaysia | Orangutans |
| Gunung Mulu | Sarawak, Malaysia | Caves and rainforest |
| Batang Ai | Sarawak, Malaysia | Longhouses and rainforest |
| Tanjung Puting | Central Kalimantan, Indonesia | Orangutans and klotok cruises |
| Brunei | Northern Borneo | Mosques and rainforest |
Seeing orangutans is one of Borneo’s signature wildlife experiences, and Sepilok in Sabah is among the most accessible places to learn about their rehabilitation and conservation.
The Sepilok Orangutan Rehabilitation Centre lies near Sandakan in northeastern Sabah and cares for orphaned and displaced orangutans before suitable animals can return to the forest.
A visit is not comparable to a zoo.
The surrounding forest is part of the experience, and orangutans have room to move through their natural environment. Sightings and behavior therefore vary.
Visitors should not expect every animal to appear on command.
Allow enough time to observe quietly rather than treating Sepilok as a quick photo stop.
Sepilok is particularly useful because several wildlife attractions can be combined in the same area.
Depending on your itinerary, consider:
Combining Sepilok with Kinabatangan creates one of the strongest introductory wildlife itineraries in Sabah.
The Kinabatangan River is one of the best places in Sabah for observing Borneo’s wildlife from a boat.
The Lower Kinabatangan supports an exceptionally rich ecosystem, and 26,000 hectares have been gazetted as the Kinabatangan Wildlife Sanctuary. The river itself stretches around 560 km, making it Malaysia’s second-longest river.
Wildlife that may be encountered includes:
Sightings are never guaranteed.
That unpredictability is part of observing genuinely wild animals.
Both are worthwhile.
Early-morning cruises can be particularly atmospheric as the forest becomes active, while late-afternoon outings provide another chance to watch animals moving toward the riverbanks before dusk.
Staying at least 2 nights allows multiple cruises and gives you a much better chance of seeing different species than a rushed single excursion.
Danum Valley is one of Borneo’s outstanding destinations for travelers who want to experience rainforest rather than simply visit individual wildlife attractions.
Located roughly 80 km from Lahad Datu, the conservation area is protected as a Class 1 Protection Forest Reserve. Sabah Tourism identifies wildlife here including orangutans, banteng, clouded leopards, slow lorises, proboscis monkeys, and Bornean elephants.
Activities can include:
The forest itself is the highlight.
Expect enormous trees, vines, insects, bird calls, humidity, and the possibility of seeing wildlife rather than guaranteed encounters.
Danum Valley is also home to extraordinary tropical trees.
Sabah Tourism notes that the yellow meranti tree nicknamed Menara has been measured at 100.8 m (330.7 ft), making it the world’s tallest known tropical tree.
It provides some perspective on the scale of Borneo’s lowland rainforest.
Mount Kinabalu is Borneo’s most famous mountain and rises to 4,095 m within Kinabalu Park.
UNESCO describes it as the highest mountain between the Himalayas and New Guinea.
Kinabalu Park is itself a UNESCO World Heritage Site and covers approximately 75,370 hectares.
Its habitats range from tropical lowland and hill rainforest through montane forest to sub-alpine vegetation.
You do not need to reach the summit to appreciate the area.
Travelers can also visit for:
Summit climbers should plan ahead.
Climbing Mount Kinabalu is controlled, and permits, accommodation, guides, and other arrangements are subject to current park rules and availability.
Do not arrive assuming you can organize a summit climb immediately.
Check current Sabah Parks requirements before finalizing your trip.
Kota Kinabalu is the main gateway to much of Sabah and is worth using as more than an overnight transit point.
The waterfront city offers:
One of its biggest advantages is how quickly a city stay can be combined with the coast.
Nearby islands provide opportunities for:
Kota Kinabalu therefore works particularly well at the beginning or end of a more demanding wildlife itinerary.
Borneo’s appeal extends underwater.
Sabah is internationally known for diving, with the waters around Sipadan particularly associated with rich marine life.
Divers may encounter:
Access to Sipadan itself is controlled, and permits are limited.
Travelers planning a diving trip should therefore verify current permit arrangements with licensed operators before choosing accommodation or travel dates.
Nearby diving areas can provide alternatives when Sipadan permits are unavailable.
Even if diving is the main purpose of your trip, consider combining the coast with Sepilok or Kinabatangan for a trip that includes both marine and terrestrial wildlife.
Kuching is the natural starting point for many trips through Sarawak and provides a relaxed introduction to the region’s history, food, and cultures.
The city sits beside the Sarawak River and works particularly well as a base for several excursions.
Spend time around:
From Kuching, travelers can reach wildlife centers, national parks, and cultural attractions without immediately committing to a remote jungle expedition.
Bako National Park is Sarawak’s oldest national park and one of the easiest places near Kuching to combine hiking with wildlife watching.
The park contains mangroves, rainforest, coastal cliffs, beaches, and varied vegetation in a relatively compact area. It is particularly known for proboscis monkeys.
Other possible wildlife includes:
Trails vary considerably.
Some are short walks, while others lead farther through forest toward viewpoints and secluded beaches.
Sarawak Tourism identifies March through October as generally better for trekking and wildlife spotting at Bako because conditions tend to be drier, while heavier rain is more common from November through February.
Weather can still be wet at any time in a tropical environment.
Travelers visiting Kuching can also consider Semenggoh Wildlife Centre, another important place associated with orangutan rehabilitation.
The experience differs from spotting a fully wild orangutan during a long rainforest expedition.
Semi-wild orangutans move through the surrounding forest, and their appearances can vary according to natural food availability and other conditions.
This means a visit should never be treated as a guaranteed wildlife performance.
Semenggoh is especially useful for travelers who want an orangutan-focused experience but do not have time to travel across Sabah or Indonesian Kalimantan.
Gunung Mulu National Park is one of Borneo’s most extraordinary landscapes, combining primary rainforest, limestone pinnacles, mountains, rivers, and immense cave systems.
The park in Sarawak is a UNESCO World Heritage Site covering approximately 52,864 hectares. UNESCO describes it as the world’s most studied tropical karst area.
Its scale is difficult to appreciate until you encounter the caves.
UNESCO records at least 295 km of explored caves within the park and thousands of plant species across 17 vegetation zones.
One of Mulu’s best-known natural spectacles happens around Deer Cave.
Large numbers of bats can emerge around dusk to feed, creating swirling formations in the sky when conditions are suitable.
Nature determines whether and how the spectacle occurs, so exact timing and visibility can vary.
More adventurous visitors can consider the famous limestone Pinnacles.
This is not a casual sightseeing walk.
The experience involves trekking and requires appropriate fitness, planning, and current arrangements with the park.
Mulu also has more accessible cave experiences for visitors who do not want a demanding multi-day trek.
A visit to Borneo becomes more meaningful when it includes the people who have lived with its rivers and forests for generations.
Sarawak is home to numerous Indigenous communities, including Iban and other Dayak peoples.
Traditional longhouses historically bring multiple families together under one extended structure and remain an important cultural feature in parts of Borneo.
Some itineraries around Batang Ai and other regions include opportunities to visit communities and learn about:
Approach these visits as cultural exchanges rather than performances staged solely for tourists.
Choose experiences that involve local communities directly and respect photography rules, private areas, customs, and instructions from hosts.
For travelers visiting Indonesian Borneo, Tanjung Puting National Park in Central Kalimantan is one of the island’s outstanding orangutan destinations.
The classic experience involves traveling along the Sekonyer River aboard a traditional klotok, a wooden riverboat that can also serve as accommodation during multi-day journeys.
Indonesia’s official tourism site highlights orangutans, proboscis monkeys, crocodiles, and more than 220 bird species in the park.
Camp Leakey was established in 1971 and remains closely associated with orangutan research and conservation.
A Tanjung Puting itinerary can include stops at orangutan research or rehabilitation sites as the boat travels deeper into the park.
The river journey is as important as the destination.
From the deck, visitors can watch rainforest slide past, listen for primates, look for birds, and experience a part of Borneo where waterways remain essential transport corridors.
Kalimantan covers the Indonesian portion of Borneo and offers far more than orangutan viewing.
Indonesia’s tourism authority highlights the region’s tropical rainforest, major rivers, traditional wooden-boat journeys, caves, and Dayak cultural heritage.
Travel here can involve:
Distances and transport can be more demanding than on a straightforward Sabah itinerary.
Travelers should therefore avoid trying to combine several Kalimantan provinces in a short trip.
Brunei occupies a small part of northern Borneo and provides a very different experience from Sabah, Sarawak, or Kalimantan.
Its highlights include:
Kampong Ayer is particularly distinctive: an extensive settlement built along the Brunei River, with houses and community facilities connected by waterways and walkways.
For nature-focused travelers, the forest of Temburong offers another opportunity to experience Borneo’s tropical environment.
Brunei fits most naturally into a longer itinerary rather than being essential to every first Borneo trip.
Borneo supports extraordinary biodiversity.
Depending on the region, habitat, season, and luck, visitors might encounter:
| Wildlife | Possible Areas |
| Orangutan | Sepilok, Danum Valley, Kinabatangan, Semenggoh, Tanjung Puting |
| Proboscis monkey | Kinabatangan, Bako, Tanjung Puting |
| Bornean elephant | Kinabatangan, Danum Valley and other Sabah habitats |
| Sun bear | Sabah forests and conservation centers |
| Hornbills | Sabah, Sarawak, Kalimantan |
| Crocodiles | Kinabatangan and other rivers |
| Macaques | Widespread |
| Bearded pig | Bako and other forests |
| Sea turtles | Sabah marine areas |
| Reef sharks | Sabah diving sites |
Wildlife lists should never be interpreted as guarantees.
Even expert guides cannot control where wild animals appear.
There is no single best place because the experiences differ.
Best suited to travelers wanting an accessible conservation and rehabilitation experience.
Provides the possibility of seeing wild orangutans as part of a broader river safari.
Best for travelers who want an immersive primary-rainforest experience where orangutans are one of many possible wildlife sightings.
Convenient for visitors based around Kuching.
Offers a distinctive multi-day riverboat experience combined with orangutan-focused conservation and research sites.
For a first trip, combining Sepilok + Kinabatangan + Danum Valley creates a particularly varied Sabah wildlife itinerary.

Borneo can be visited throughout the year, but the best period depends on the region and the activities you plan.
The island has an equatorial tropical climate, so heat, humidity, and rain are possible year-round.
There is no single dry season that applies perfectly to every part of Borneo.
| Trip Type | General Consideration |
| Rainforest wildlife | Possible year-round |
| Hiking | Drier periods generally easier |
| Bako National Park | March-October often better for trekking |
| Diving | Depends on specific coast/site |
| Mount Kinabalu | Weather can affect climbing year-round |
| River safaris | Operate in varied conditions |
| Mulu caves | Possible year-round; weather affects outdoor activities |
Rain should not automatically be considered bad luck.
Rainfall sustains the rainforest you have traveled to see.
The bigger concern is prolonged or severe weather that affects trails, boats, flights, climbing, or road access.
Around 10 to 14 days works well for a first Borneo trip focused on one Malaysian state, while 2 to 3 weeks allows travelers to combine regions more comfortably.
| Trip Length | Suggested Focus |
| 5-7 days | One compact region |
| 10 days | Sabah wildlife highlights |
| 14 days | Sabah in depth or Sabah + Sarawak |
| 2-3 weeks | Multiple regions |
| 3+ weeks | Malaysia + Kalimantan/Brunei |
Borneo rewards slower travel.
Remote rainforest lodges, river transfers, regional flights, boats, and mountain journeys mean that moving between highlights can take longer than distances on a map suggest.
Recover from your journey, visit markets, enjoy local food, and take a coastal or island excursion.
Head inland for mountain views, botanical diversity, and cooler air.
Travelers climbing Mount Kinabalu will need to structure these days around their confirmed climbing arrangements.
Travel to the Sandakan region and visit the orangutan rehabilitation center and nearby conservation attractions.
Stay beside the river and take multiple morning and evening wildlife cruises.
Finish with a deeper rainforest experience involving guided walks, wildlife observation, and night activities.
This route balances accessible conservation experiences with genuine wilderness.

Pack for heat, humidity, rain, insects, and uneven ground.
Useful items include:
For serious trekking, climbing, or diving, the packing list will need to be more specialized.
Borneo’s wildlife is one of its greatest attractions, but tourism works best when animals remain wild.
Follow several basic principles:
A photograph is never worth disturbing an animal.
A little preparation makes a substantial difference.
Borneo works best when you choose a few exceptional experiences rather than trying to cover the entire island.
For a first wildlife-focused journey, Sabah provides a compelling sequence: begin around Kota Kinabalu and Kinabalu Park, see orangutans at Sepilok, cruise the Kinabatangan River, and spend several days inside Danum Valley.
Sarawak adds a different character through Kuching, Bako’s proboscis monkeys, Indigenous cultural experiences, and the monumental caves of Gunung Mulu. Indonesian Kalimantan becomes particularly rewarding for travelers who have more time and want the slower rhythm of a klotok journey through Tanjung Puting.
Wherever you go, leave room for uncertainty. Borneo’s strongest experiences are not scheduled performances: an orangutan appearing between trees, hornbills flying across a river, bats emerging from a cave, or the sound of rainforest after a tropical downpour are memorable precisely because nature determines when they happen.
Borneo’s major highlights include orangutans, Kinabatangan River wildlife cruises, Danum Valley, Mount Kinabalu, Gunung Mulu National Park, Bako National Park, Indigenous cultures, tropical islands, and diving.
Sabah is particularly practical for a first trip because travelers can combine Kota Kinabalu, Mount Kinabalu, Sepilok, Kinabatangan, Danum Valley, and coastal experiences within one region.
Kinabatangan, Danum Valley, and Tanjung Puting offer opportunities to see orangutans in rainforest environments, although sightings are never guaranteed. Sepilok and Semenggoh provide different rehabilitation-focused experiences.
Orangutan experiences are possible throughout the year at several destinations, but sightings of genuinely wild animals depend on food availability, weather, location, and animal movements.
No. Borneo also offers mountain climbing, diving, caves, beaches, river journeys, cities, food, Indigenous cultures, longhouses, and rainforest trekking.
Around 10 to 14 days is a useful length for a first trip focused on one region. Allow 2 to 3 weeks if combining Sabah and Sarawak or adding Kalimantan.
The summit climb is physically demanding because of the altitude, elevation gain, terrain, and early summit attempt. Climbers should prepare appropriately and follow current permit, guide, and accommodation requirements.
No. Kinabatangan is rich in wildlife, but animals move freely through their habitat. Multiple morning and evening cruises generally provide more observation opportunities than a single outing.
Yes, particularly for travelers interested in caves, geology, rainforest, hiking, and unusual natural landscapes. UNESCO recognizes Mulu for both its exceptional biodiversity and karst features.
Yes, but allow enough time. Crossing between regions can involve flights and additional immigration procedures, so combining Sabah, Sarawak, and Kalimantan is better suited to a longer itinerary.
