Off Thailand’s southeastern coast Koh Chang is Thailand’s second-largest island after Phuket. The Koh Chang National Marine Park occupies most of Koh Chang as well as several nearby islands. The island is located 140 mi/225 km southeast of Bangkok. In recent years the island has become more popular with travelers and Thai people alike. Most of the beach resorts are located on the beautiful west coast of the island. Koh Chang has several wonderful waterfalls that allow swimming and diving from rocks. There are elephant trekking tours through the jungle and there are a dozen diving schools that will guide you to the best diving spots that Thailand has to offer. Most Thais like to go squid fishing at night and kayaking or hiking during the day.
There is a local information repository at whitesandsthailand.com that hosts maps and tips.
Arriving on Ko Chang by boat, you are greeted by many truck taxis waiting to take you around the island. The roads are steep and winding at times, but these local treks will be memorable.
