Day by day

Day by day

Day 1

Arrive Sepilok

On arrival at Sandakan airport, you will be met and transferred to Sepilok; a nature haven and perfect base to visit the nearby animal sanctuaries and rehabilitation centres. Check into your lodge and enjoy your surroundings. At dusk you will visit the canopy walk at the Rainforest Discovery Centre in time to catch the red giant flying squirrels emerge from their nests and glide between the trees. Return to the lodge for dinner.

Overnight: Sepilok Nature Resort (B, L, D)

Day 2

Sepilok, Sun Bears & Labuk Bay

After breakfast, visit the Orangutan Rehabilitation Centre in time for their morning feed (10:00). This sanctuary rehabilitates previously captive or orphaned orangutans (through deforestation, poaching, etc.) to their natural surroundings, ready for release when they are capable of supporting themselves in the wild. You then have a tour of the Sun Bear Conservation Centre to learn all about the project to save these adorable bears, the smallest and least known members of the species, whose population is rapidly diminishing. After lunch you will head to Labuk Bay Proboscis Monkey Sanctuary in time for the afternoon feedings. Proboscis monkeys, found only in coastal swamps close to rivers in certain areas of Borneo, are lucky to have survived after the area near the mangrove swamps was nearly lost to palm oil plantations. Plans for oil were dropped, and now around 60 monkeys regularly come here to feed. Famed for their large nose which acts as a resonator for their loud honking noises, these pot-bellied primates really are a sight to behold.
