Gunung Leuser National Park (Indonesia). 'This vast jungle of northern Sumatra is filled with cheeping, squeaking, growling animal life. It’s a naturalist’s and adventure traveller’s fantasy. Sitting pretty beside a chocolate coloured river, the village of Ketambe is a relaxing place to rest up for a few days. More importantly, it makes a great base camp for multi-day hiking expeditions.' http://www.lonelyplanet.com/indonesia/sumatra/bukit-lawang
