Best Beaches in Koh Samui
20 places found in Koh Samui
Koh Samui's beaches wrap around the entire island, each with a distinct character. Chaweng Beach is the longest and most popular — 7 km of white sand with beach bars, water sports, and beachfront dining. Lamai is more laid-back with better snorkelling at its rocky southern end.
The northern beaches offer tranquility. Maenam has shallow, calm water perfect for families and paddleboarding. Bophut's Fisherman's Village combines a narrow beach with the island's most charming pedestrian strip. For something secluded, explore the southern coast around Thong Krut.

Thong Nai Pan
Thong Nai Pan is the pair of horseshoe bays on Koh Phangan's northeast corner that many rate the island's best all-round base — Thong Nai Pan Yai, the larger southern bay with a village feel and family resorts, and Thong Nai Pan Noi, the more polished northern bay where the island's smarte.
