This WHS is spread out all over Sumatra. All jungle national parks look the same to me and so to find a reason to check this WHS off your list is to get to Medan in North Sumatra and visit the Bohorok Orangutan rehabilitation center, a two hour drive from Medan. Orangutan babies are collected illegally by killing their mothers. They are then sold as pets. The problem is that when the Orangutans grow up and become unmanageable, they are abandoned. The rehab center is to save these animals and train them to survive in the wild with some supplemental milk and food. Orangutan rehab centers exist also in Borneo but this site is more primitive and so much more natural then others I have visited. I visited this site in August 1994 and also nearby Lake Toba and the native villages around the lake.

Bohorok is part of Gunung Leuser National Park.
