Bukit Lawang is a pleasant getaway from the polluted streets of Medan. The village sits on the eastern outskirts of Gunung Leuser National Park, a huge sanctuary for the flora and fauna of the region, but BL is maybe most famous for the Bohorok Orangutan Rehabilitation Center. These attractions has made Bukit Lawang one of the most popular destinations in northern Sumatra, and today the town exists almost only for the purpose of serving the tourists.
The Bohorok Orangutan Rehabilitation Center was started in 1973 by two Swiss zoologists, Regina Frey and Monica Boerner, and funded by Frankfurt Zoological Society and WWF. The intention was to help orangutans that had been displaced due to land clearing or recovered from captivity. In the first years they had great success in the four steps of rehabilitation; removal from captivity, a quarantine of at least three months, release into the forest around the center and finally taken deep into the rainforest to be released into the wild permanently.
