Explore Koh Chang

Thailand’s picturesque Koh Chang island is a nature lover’s dream, with white sandy beaches, warm turquoise water and swaying palm trees. This relaxing island is home to an array of life, both above and below the waves. Mountainous rainforests and jungle host lots of interesting land species, while the surrounding ocean holds breathtaking reefs, rocky pinnacles and a wealth of colorful, thriving marine life. It is the largest of 52 islands that make up the entirety of the Koh Chang Marine National Park.

There are roughly 30 dive sites around the island ready to be explored, including wrecks, reefs, tunnels and swim-throughs. Scuba diving here is suitable for beginners and advanced divers alike. A lot of the sites are around the main island, while there are others peppered around smaller nearby islands where boats make diving trips. Koh Rang National Park is also in this area, and offers more great diving in protected waters where life is overflowing.

There are a few great dive centers on the island, and most have offices at Bangbao Pier, from where the majority of dive trips depart. Divers can also opt to stay in dive resorts, and liveaboards are also an option, though there aren’t a huge number in this small part of Thailand. Koh Chang would also be ideal to take open water dive courses thanks to its calm sea and bustling marine life. Other courses that are great to take here are wreck specialties, as there are some amazing wreck dive sites that absolutely should not be missed.
