Koh Samui is a blend of all that's best in Thailand. There are few places in the world that equals Koh Samui for its white sandy beaches, clear warm water and its tranquility. The beaches here on Samui offer a wide range of options for its holiday makers, from busy active beaches (Chaweng), to quite tranquil peaceful beaches (Bo Phut,Maenam) as well as many hidden beachs in quite bays. Koh Samui has it all!
In the summer months the waters in Chaweng can occasionally have some wind swell & surf, so be prepared for strong rip tides or side shore currents. The waters are shallow, but inexperienced swimmers should either stay close to shore or swim with other people.
In the center of the North coast of the island, Maenam offers spectacular views of Ko Phangan to the North, and the Ang Thong National Marine Park to the East. The waters are calm and clean, being protected from the North Easterly currents by Ko Phangan. Because the sans are golden rather than white Meanam is usually much less crowded than Lamai or Chaweng.
Bophut is the beach/bay just to the east of Maenam. Its lifestyle is relaxed and more traditional than the larger communities, referring to itself as Fisherman's Village.
Bang Rak, just two kilometers east of Bhophut, and part of Bhophut 'province' is also known by the name Big Buddha Beach, after the 19-metre gold tinted statue of the ancient spiritual master which overlooks the entire bay (Big Buddha). Bang Rak is quite close to the airport, and is one of the calmest beaches, though the huge sweep of its jade colored waters are often a bit murky.
Choengmon is one of the smallest of Samui's tourist beaches, but lies in a secluded bay on the northeastern tip of the island, making it perfect for those who want peace and quiet.
