Gunung Leuser National Park is one of the last places to spot the endangered Sumatran Orangutan in the wild. It's also home to other unique wildlife species such as the Sumatran Tiger and the Sumatran Elephant. To protect & preserve our Jungle, it's important that all visitors follow the rules.

Orangutans are genetically very close to humans (96.4%). The orangutans might catch your diseases (and vice versa). A simple cold for you can be very dangerous for them!

This is dangerous for both you and the orangutans and other wildlife.

It is incredibly dangerous to stand between two orangutans, especially if it concerns a mother and her baby!

Do not call or lure the orangutans or make monkey sounds. This can cause them stress and it also disrupts their natural behavior.

Be as quiet as possible when observing the orangutans, do not use the flash on your camera and do not make any sudden movements as this can be perceived as a threat.

Sumatra's Jungle is a unique ecosystem with a very high biodiversity. All plants, leafs, seeds and fruits play a crucial role in maintaining a healthy ecosystem.

Do not leave anything behind (plastic bottles or bags, food scraps, tissues, cigarette butts etc.) and collect rubbish along the way if necessary.
