The critically endangered Sumatran orangutan survives only at the northern tip of Sumatra, and the riverside village of Bukit Lawang, gateway to UNESCO-listed Gunung Leuser National Park, offers the world's most intimate way to meet them: steep, sweaty jungle treks where you share the forest floor with semi-wild apes. Unlike Borneo's gentle boat cruises, this is a physical adventure through primary rainforest alive with Thomas leaf monkeys, gibbons, and hornbills, and the June to July fruiting season draws orangutans closest to the trails. Every trek requires a licensed local guide, whose fees directly sustain the community that protects this forest.
