The Bohorok Orangutan Centre at Bukit Lawang in Indonesia is one of the only places in the world where you can see orangutans in the wild.

Half a dozen orangutans were swinging in the trees around us when we snapped this photo. The rangers were feeding some of the orangutans on a feeding platorm a few feet away.

Bukit Lawang is a small village deep in Sumatra’s forest, packed with backpacker hostels and cafes. To get there, we took a ferry from Penang, Malaysia to Medan, Indonesia, and jumped on board a mini-bus to Bukittinggi. From Bukittinggi, we took a local bus on roads with potholes deep enough to lose a car.
