Koh Chang, one of the largest Thai islands in the Gulf of Thailand, contains dense, steep jungle. Mu Koh Chang National Park, a preserve with hiking trails and waterfalls such as tiered Klong Plu, covers the interior and extends to offshore coral reefs.
The coast is dotted with beaches and villages including Bang Bao, built on piers. Hat Tha Nam (aka Lonely Beach) has a waterfront party scene that attracts backpackers.
With about 5,000 permanent residents the island is not heavily populated, but tourism (and development) has increased dramatically over the last few years. Despite this, tourism is nowhere near at the levels of Phuket and Samui, and as such, the island offers a much better experience for anyone willing to make the effort to get there.
