Ko Chang (เกาะช้าง) is an island in Trat Province, Eastern Thailand. Ko Chang is Thailand's second largest island, and the biggest in Eastern Thailand. With about 5,000 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. 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 is far from quiet in high season. Regarding services and activities specifically aimed at tourists prices have reached such a level that the islanders are pricing themselves out of the market when compared to the other islands.
