Set amid mangrove forest and reached via a track through an oil-palm plantation, Labuk Bay Proboscis Monkey Sanctuary functions as a companion to the more famous orang-utan sanctuary at Sepilok. Most visitors come on a day-trip from Sandakan or Sepilok, which is significantly closer, but it’s also possible to stay overnight.
Two large observation platforms, each with two feeding times, offer perfect vantage points from which to view the long-nosed proboscis monkeys; at the same time you can also see silverleaf monkeys scavenge fruit left behind, and there’s some fantastic birdlife including hornbills. On a day-trip you could see all four feedings if you like, or even leave after just one, but it’s more usual to see one from each platform.
If you make arrangements in advance then it’s possible to combine watching the monkey feeding with other activities. These include a short jungle trek or a bird-watching walk (each 1hr; RM30) or a boat trip (2hr; RM250/boat) to a fishing village. If you’re staying the night then you can also sign up for a firefly walk (45min; RM20) and a morning birdwatching walk (1hr; RM30).
