Where to See Borneo's Rainforest: 3 Parks Ranked by Real Odds

Q: Where is the best place to see Borneo's Rainforest?

Kinabatangan Wildlife Sanctuary. In Kinabatangan Wildlife Sanctuary, Malaysia, the chance of seeing all 4 (orangutan, proboscis monkey, rhinoceros hornbill and gibbon) on the same day is under 5%, the highest of the 3 parks where all of them live, and over a three-day visit it rises to about 30%. Next come Tanjung Puting National Park (under 5% a day) and Sepilok (under 5% a day). It multiplies each animal's daily chance, as if they were independent, so read it as a rough guide.
