Sepilok:

 

The Rainforest Discovery Centre (RDC) at Sepilok, located within the Kabili‑Sepilok Forest Reserve near Sandakan, offers a unique and accessible opportunity to observe a variety of Bornean mammals in a compact setting. By day, visitors may spot Bornean orangutans occasionally along the canopy walkway, as well as pig‑tailed macaques, north Bornean gibbon and occasionally the odd sighting of the shy grizzled langur. But the real draw is the RDC’s guided night walks, during which nocturnal species emerge: observers may encounter the tiny western tarsier, enigmatic Philippine slow loris, moonrats, Malay (stink) badgers, mouse‑deer, civets, and the show-stopping red giant flying squirrel as twilight falls. This blend of diurnal and nocturnal mammals complemented by the lush rainforest backdrop makes the RDC a compact, wildlife-rich stop well worth including in any Sabah itinerary.
