Responsible Trekking in Bukit Lawang

Go deeper into the jungle to see wild orangutans, hornbills and other interesting wildlife.

We can’t recommend Sumatra EcoVentures enough! They are helpful, knowledgable, and environmentally responsible.  Heri and Putra were extremely knowledgeable about the animals and plants of the forest. Throughout the hike, they prioritized protecting the animals that we were viewing.
