Chaweng and Lamai with Older Children and Teens

Chaweng (about 7 km) and Lamai are Koh Samui's most developed beaches and work best for families with older children and teenagers rather than toddlers. Reasons: the central parts of Chaweng offer the island's most reliable swimming for confident swimmers (sandy bottom, gentle slope); there are water sports, shops and many casual restaurants; and the beach towns have pharmacies, clinics and supermarkets close by. The trade-offs: both are busy, and the east coast faces the northeast monsoon - roughly November to January, onshore waves can create dangerous rip currents. Obey the red flags (red means do not swim); if caught in a current, swim parallel to the beach, not against it. The northern end of Chaweng is very shallow at low tide and calmest for smaller kids. All beaches are free and public.
