Best Beaches in Koh Samui

18 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.
