Explore the rainforests and wetlands of Malaysian Borneo, from Kinabatangan and Tabin to Danum Valley, on an immersive wildlife expedition led by biologist and conservationist Dr Martin Cohen. Gain expert insight into these rich ecosystems as you search for orangutans, sun bears, gibbons, proboscis monkeys and hornbills, following in the footsteps of Alfred Russel Wallace in one of the world’s most biodiverse regions.

Explore Borneo’s key conservation and wildlife regions, from the Bornean Sun Bear Conservation Centre, Sepilok Orangutan Rehabilitation Centre and Rainforest Discovery Centre to Sabah’s most important ecosystems, including Tabin Wildlife Reserve, Danum Valley and the Kinabatangan wetlands. Stay in remote forest lodges and experience guided wildlife cruises, treks and night walks in one of the world’s richest tropical rainforests.

You will be accompanied by biologist and conservationist Dr Martin Cohen, who will lead the scientific interpretation of the journey, bringing deep expertise and a research-led perspective on the ecology and conservation of Malaysian Borneo. Through his insights in the field, Martin will help connect each habitat and wildlife encounter to the wider scientific understanding of rainforest systems, biodiversity and conservation challenges. A local English-speaking tour leader will also assist throughout, providing practical guidance and regional context as you travel through this remarkable landscape.

The tour has a maximum group size of just 16 guests and is ideal for those with all levels of expertise, as it acts as a fantastic introduction to Malaysian Borneo's amazing flora, fauna and geology and how it is being protected, whilst allowing those with a deeper understanding to observe a great many species.

In partnership with Intrepid Travel.


Day 1: Arrive in Sandakan

Welcome to Sandakan! The gateway to some of Sabah’s richest wildlife areas that boast elephants, orangutans, sun bears, proboscis monkeys and myriad species of birds, Sandakan is also a culinary paradise with amazing seafood and local delicacies unique to the cultural melting pot of people who have settled here over the centuries. You will be met upon arrival at Sandakan airport and then transferred to your hotel located in Sandakan. 

In the evening, your accompanying guide Martin Cohen and tour leader will give an introductory talk on the expedition ahead and you can enjoy a welcome meal together.

Day 2: Bornean sun bear, Sepilok Orangutan Rehabilitation, Rainforest and Discovery Centres

After breakfast, depart for the Bornean Sun Bear Conservation Centre, which is located next to the Sepilok Orangutan Rehabilitation Centre. Whilst here, enjoy an educational talk on sun bear conservation by founder Dr Wong or one of his team members before we explore this wonderful new centre, taking care of rescued sun bears that have spent many years mistreated and locked away in cages. Borneo Sun Bear Conservation Centre is giving a better life to these bears by caring for them with the hope of reintroducing them back into the wild. They are doing great work at promoting sun bear conservation in Borneo through animal welfare, conservation, rehabilitation, research, and education in order to put a stop to cruel practices. 

Afterwards, walk the short distance to the Sepilok Orangutan Rehabilitation Centre for 10am feeding time. The centre attracts tourists and researchers alike, giving them the opportunity to watch the orangutans up close in their natural habitat. A boardwalk leads to a viewing gallery and feeding platform where the apes are fed milk and bananas twice a day at 10am and 3pm by rangers. Feeding time also attracts long-tailed macaques to the area. Visiting Sepilok Orangutan Rehabilitation Centre offers a unique opportunity to observe Borneo’s incredible species up close, but it’s important to set realistic expectations. The orangutans are semi-wild and free to roam, so sightings cannot be guaranteed, and encounters are meant to be respectful and non-intrusive. 

In the afternoon, head out to the Rainforest Discovery Centre (RDC), which will involve a short amount of trekking. It sits by a lake at the edge of the Kabili-Sepilok Forest Reserve in Sandakan. Enjoy the walk along the suspension bridge which ends with the only canopy walk (147 metres long) in Sandakan. The 28-metre high walkway puts you among the rainforest giants such as the mengaris trees. Birdwatchers will be fascinated by this place as it has one of the rarest birds in Sabah, the Borneon bristlehead, and another 250 species of birds like hornbills, broadbills, pittas and kingfishers. The centre is managed by the Sabah Forestry Department. The main purpose of the RDC is as an environmental education centre for students and teachers. Return to your resort on foot.

Pace and physicality

This is an active, expedition-style journey with a steady pace and a strong focus on outdoor exploration in tropical rainforest environments. You should expect early starts, full days in the field and a mix of guided walks, boat cruises and overland travel, often in humid, warm conditions with high biodiversity and limited infrastructure. Many activities take place on uneven jungle trails, boardwalks and riverbanks, requiring a reasonable level of mobility and comfort with walking in hot, occasionally muddy or slippery conditions.

Travel is an integral part of the experience, with a combination of road journeys, river transfers and short domestic flights between key regions of Sabah. Road conditions can vary outside major centres, with some longer drives on winding or uneven roads, while river journeys offer a slower, immersive way to access remote wildlife habitats. The overall pace is immersive rather than strenuous, balancing active wildlife encounters with time to rest at remote rainforest lodges.

Weather

Mid-August in Sabah falls within a classic equatorial tropical climate, characterised by consistently warm temperatures, high humidity and relatively stable conditions year-round. Daytime heat is typically accompanied by a strong, humid atmosphere, while evenings remain warm and close. Rain can occur at any time, often in the form of short, heavy tropical showers that pass quickly and are followed by clear or partly sunny skies. Weather conditions can vary between rainforest interiors, river valleys and coastal areas, but overall remain typical of a lush, tropical environment where biodiversity thrives year-round.

Accommodation

Accommodation in Malaysian Borneo is generally mid-range to boutique in style, with most lodges and resorts ranging from 2-star to 4-star standards. In rainforest areas like the Kinabatangan River and the Danum Valley, expect eco-lodges and jungle retreats with basic but comfortable amenities, often designed to blend with nature rather than impress with opulence. You should anticipate warm local hospitality, practical comforts, and an immersive experience in Borneo’s unique natural environment.
