Bukit Lawang, the gateway to Gunung Leuser National Park, is a place where adventure and conservation meet. Treks to see wild orangutans, river tubing on the Bohorok, cooking classes with local families, and stays in riverside eco-lodges offer a blend of culture, wildlife, and rainforest immersion. This is one of Sumatra’s most rewarding destinations—where every visit supports both the community and the protection of the Sumatran orangutan.
