Sumatra Jungle Challenge Trek:

  • Join an expedition to the breathtaking Leuser Ecosystem in Sumatra;
  • Track wildlife, visit local communities, and swim in hot springs;
  • Raise funds to support orangutan conservation.
This 10 day trip takes place in the Leuser Ecosystem, one of the only places in the world where you can still see the Sumatran orangutan in the wild. They share these forests with a whole host of other wildlife; gibbons, elephants, hornbills, Thomas' leaf monkeys, macaques, sunbears and the elusive Sumatran tiger are just a handful of the thousands of animal and plant species found in this unique World Heritage ecosystem.  

Throughout your trek you will learn to spot an astounding array of plants and wildlife and hone many rainforest skills. Sumatra's forests are a last refuge for many of the world's most endangered species. This trek is designed to make you feel at home in their world, and raise funds for conservation projects.
