Chaweng is the largest and most popular of Koh Samui’s beaches and is usually divided into three sections: North Chaweng, Central Chaweng and Chaweng Noi (Little Chaweng) around a headland to the south. Chaweng Beach is the longest beach on Koh Samui’s east coast.
The beach is approximately 7 km long with powdery white sand. It is bordered by the emerald-blue waters and a coral reef where waves break, leaving the bay quite peaceful. Not far from the beach, there are two small islands near the reef. After swimming, you can explore the nearest one by walking through shallow water or go for snorkeling and kayaking at the second island which is further out and larger.
The beach itself is usually accessed through the hotels, as there are no beach roads to disturb the peacefulness of the area. It is very relaxing but noticeably more touristy during the high season. The water is clean with normal temperatures between 25-28°C.
