The Gunung Leuser National Park, in northern Sumatra, is one of the richest tropical rainforests in Southeast Asia. Covering up to 950,000 hectares and straddling the border of North Sumatra and Aceh provinces it is one of the last places on earth, where you can see the critically endangered orangutans in the wild. This region is also a host of other wildlife. Elephants, rhinos, tigers, leopard cats, siamangs, Thomas leaf monkeys, macaques, gibbons are just a handful of the thousands of species found in this unique eco-system. It has been a Unesco World Heritage Site since 2004.
The park area climbs to 3,404m to the peak of Gunung Leuser which gave the area its name and protects a wide range of eco-systems. There are river systems, volcanoes and lakes. This rainforest is immensely biodiverse, hosting approximately 700 different species of animals - more than 175 mammals, 320 birds, 190 reptiles and amphibians. Because of the great differences in altitude and the diversity in soil, the Gunung Leuser National Park has also an enormous wealth of plant species. The flora contains approximately 10.000 plant species, including the spectacular Rafflesia Arnoldi and Amorphophallus titanum, the biggest and the highest flower in the world.
On the eastern side is the Orangutan Rehabilitation Centre, which is now one of the world's most important conservation projects. Orphaned orangutans are brought here to learn how to live in the wild again.
