One of the best examples of pristine lowland and montane rainforest in Sumatra with an exceptional range of speciality plants, reptiles, birds and rare mammals including eight species of primate.

Located in the far north-west of Sumatra, Gunung Leuser is one of the largest and best preserved national parks in Sumatra. It covers over 7,000 square kilometres of lowland, montane and swamp forest and is a particularly beautiful environment with numerous quiet river valleys and mist shouldered mountains.

The park is often described as one of the most biologically rich forests in the world as it supports an incredibly important diversity of life from unique plants and thousands of species of insect to rare mammals and over 300 species of bird. Much of the park is difficult to access though, and it has remained one of the least explored in Indonesia. It still supports an almost intact ecosystem with some very rare large mammals such as elephants, Sumatran tiger, orangutan, sun bear and Sunda clouded leopard, although many of these are exceptionally rare to see.
