Best Beaches & Islands in Koh Samui

19 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 powdery white sand with the full range of beach bars, water sports, and beachfront dining. Lamai, the island's second beach, is more laid-back with better snorkelling at its rocky southern end and a bohemian vibe that attracts returning visitors.

The northern beaches offer the most tranquil experience. Maenam is a local favourite with shallow, calm water perfect for families and stand-up paddleboarding. Bophut's Fisherman's Village combines a narrow beach with the island's most charming pedestrian strip of restaurants and shops. For something truly secluded, explore the southern coast around Thong Krut, where you'll find small bays and the departure point for boats to Koh Tan, an excellent snorkelling island.

Frequently Asked Questions

Which Koh Samui beach is best for swimming?

Chaweng and Lamai have the best swimming — long, sandy, with gradual depth. Maenam is excellent for families (very shallow for 30+ metres). Bophut is narrow with a rocky bottom in places. Avoid the southern and eastern shores for swimming — they're more rocky.

Can I island-hop from Koh Samui?

Yes. Day trips to Ang Thong National Marine Park (stunning archipelago, snorkelling + kayaking, ~1,800 THB) are the highlight. Boats to Koh Phangan (30 min, Full Moon Party or quiet beaches) and Koh Tao (1.5-2 hrs, diving) run multiple times daily.

Is Koh Samui good for families?

Very much so. Calm waters at Maenam and Chaweng, family-oriented resorts with kids' clubs, and attractions like the Samui Aquarium and Na Muang waterfalls. The island is well-developed with hospitals, international schools, and family restaurants.
