The Bornean Elephant

The animal

The Bornean elephant

2.5 hours from Sandakan, the Kinabatangan River winds through lowland forest fragments where endangered Bornean elephants constantly search for food. Tracking these heavy animals from a small boat allows you to cover large distances without pushing through the dense tropical undergrowth. Plan a three-day river stay from March to October, when elephants are a realistic target if herds are in the area.

On 27 June 2024, the IUCN assessed the Bornean elephant as a distinct subspecies (Elephas maximus borneensis) and classified it as Endangered. The assessment confirmed a population of roughly 1,000 wild individuals and only about 400 breeding adults capable of sustaining the line. Genetic sequencing in 2026 proved they are an ancient lineage that became isolated on Borneo between 11,000 and 18,000 years ago during a severe population bottleneck rather than a feral herd introduced by traders. This history and modern habitat loss mean they exhibit high levels of inbreeding.

They are smaller than mainland Asian elephants but adult males still reach 2.5 m at the shoulder and weigh up to 3,000 kg. Their distinct features include a rounder face, relatively larger ears and a long tail that often drags on the ground.

Sabah's lowland forest reserves

The Kinabatangan River offers the most accessible viewing but it is not the only place to find them.

Deramakot Forest Reserve is an excellent alternative for dedicated wildlife watchers. It is a sustainably managed Forest Stewardship Council certified reserve. Tracking here happens via 4WD vehicles on old logging roads at night. This provides long-duration terrestrial views in a massive road network.

Tabin Wildlife Reserve covers 1,225 square kilometres of lowland dipterocarp forest. Sightings in the dense secondary growth are sporadic but targeted treks to the Lipad Mud Volcano provide a focal point where herds gather for sodium and calcium.

In Danum Valley's unbroken primary forest, elephants are a bonus seen with luck.

Elephant movements and seasonal floods

The sporadic nature of elephant sightings along the Kinabatangan is driven by their need for food and the region's hydrology. Dozens of elephants feeding beside the river can stay in view for days before moving on.

A Bornean elephant's home range in a continuous forest is between 250 and 400 km2. Rapid resource depletion in the fragmented Kinabatangan forces herds to expand their range up to 600 km2 and travel faster to find the next patch of suitable forest. They average a movement rate of 1.81 km a day. Telemetry tracking shows they use high-speed, low-trajectory movements to cross active oil palm estates to move between protected areas.

The river's seasonal floods dictate where they can stand. The peak season from March to October is the optimal period for viewing. The herds move out to the exposed riverbanks of the main channel to drink, bathe and feed on pioneer grasses as inland swamps dry up. The severe Northeast Monsoon floods between December and February shrink the available dry habitat dramatically. This pushes the herds into isolated high-ground fragments deep inland and drastically reduces visibility from the river.

River itineraries and lodge locations

Seeing them requires patience because the herds are highly nomadic. Plan around time on the river and the boatmen's knowledge of the herds' movements. A typical 2-night Kinabatangan itinerary yields an excellent chance of encountering orangutans and proboscis monkeys while elephants remain a bonus.

Sightings can happen daily if a herd crosses into a lodge's operational radius. Between riverbank visits, herds may cross an inland road or move into an oxbow lake. Book a longer stay of 3 or 4 nights to maximise your odds.

Fresh signs and riverbank tracks

Guides read fresh signs along the banks and share news with other boatmen to track the herds.

• The boatman network: The most vital tool is the informal network of boatmen who share locations via VHF radio and WhatsApp. The location is shared when a herd moves to the river at dawn so boats can reach the area before the elephants retreat into the shade.
• Bank slides and footprints: Elephants do not step lightly down the steep Kinabatangan banks. They slide to leave deep gouges in the mud accompanied by massive circular footprints. Fresh, wet mud indicates a recent crossing.
• Vegetation damage: Bornean elephants are mixed-feeding megaherbivores that require massive volumes of forage daily. Guides scan the riparian reserves for snapped dipterocarp saplings, peeled bark and flattened stands of wild ginger and bamboo to locate recent feeding grounds.
• Dung analysis: Bornean elephant dung takes roughly 212 days to decay. Finding it does not mean elephants are near. Expert guides assess the moisture content and insect activity to determine if the herd passed hours or weeks ago.

Boat viewing guidelines

River-based viewing is safe and less invasive than approaching on foot if the boat is handled ethically. Approaching a herd induces stress. Official wildlife viewing guidelines set clear limits.

Boat drivers must drop their speed to under 4 km/h when within 100 m of the animals and maintain an absolute minimum viewing distance of 60 m. Encounters are limited to 30 minutes to prevent disruption to their feeding. The golden rule is never to chase or encircle a moving herd and never block their exit to the forest.

Boat engines must be put into neutral at a safe distance if a herd is swimming across the channel. Bornean elephants are strong swimmers but cutting across their path can cause panic and endanger young calves struggling against the current.

The Kinabatangan wildlife corridors

The survival of the Bornean elephant relies on restoring connectivity between the 10 isolated lots of the Lower Kinabatangan Wildlife Sanctuary. Conservation groups and plantations are buying back land and planting trees through the Corridor of Life strategy.

The World Land Trust and HUTAN have secured the 182-hectare Keruak Corridor to connect 2 previously fragmented protected areas near Sukau. They are also restoring the 45-hectare Genting Corridor from former commercial palm oil plantation land. The Borneo Conservation Trust established the Bukit Melapi–Yu Kwang Corridor. This vital 500-metre strip allows hundreds of elephants to move safely between sanctuary lots. Nestlé's Project RELeaf has planted millions of native trees to restore riparian zones.

Neighbouring oil palm plantations now collaborate on shared wildlife corridors through the Seratu Aatai Sukau Consortium founded by Whitley Award winner Dr Farina Othman. They use joint electric fencing and plant elephant food to guide the herds safely through the estates. This reduces human-elephant conflict and crop damage.

River lodge itineraries

Tell the team when you plan to travel and how many nights you have available if the herds are what you are coming for. They will recommend the lodges with the best track record and build an itinerary that gives you the time on the river you need.
