Chaweng Beach
Koh Samui's biggest and busiest beach area — a 7 km crescent of white sand backed by the island's main nightlife strip, shopping, and the widest range of hotels. Central Chaweng buzzes with beach clubs, water sports, and bars; Chaweng Noi at the southern end is calmer and more upscale. Everything you need is within walking distance, but that convenience comes with higher prices, more crowds, and noise from the nightlife strip.
