Ko Chang is Thailand's second largest island, and the biggest in Eastern Thailand. With about 5000 permanent residents the island is not heavily populated, but tourism (and development) has increased dramatically over the last few years.
Ko Chang is one of Thailand's most beautiful islands with long white sandy beaches, most half deserted. The island is also home to a wide range of wildlife, including a good selection of birds, snakes, deer and a number of elephants. The island and its vicinity are great places for snorkeling, diving and jungle hiking. The "discovery" of the island as a tourist destination since 2000 has brought on a large amount of rapid development, and while still far quieter than places like Phuket or Ko Samui, it's probably better to go now than later. Koh Chang has an area of approximately 429 square kilometres. The topography contains high mountains and complex stone cliffs. The highest mount is Khao Salak Phet which is 744 metres high, rich in fertile evergreen forest which is the main water source. Therefore, there are many waterfalls, beaches and splendid reefs in the west of the island.
