Seeing orangutans in the wild is a dream for many nature lovers. Sumatra is one of the last places on Earth where you can observe these incredible primates in their natural rainforest habitat. This guide will help international travelers understand where, how, and when to see orangutans in Sumatra ethically and responsibly.
The Sumatran orangutan (Pongo abelii) is a critically endangered species found only on the island of Sumatra, Indonesia. They live mainly in the Gunung Leuser National Park, a protected rainforest ecosystem rich in biodiversity.
Observing orangutans in the wild supports conservation efforts when done through responsible tourism.

Why Bukit Lawang?
