Chaweng Beach

Samui’s most famous strand-and its longest-is also its most energetic. Chaweng’s six kilometres of powder-soft sand form the island’s beating heart. Mornings bring paddleboarders and parasails; by night, the tempo rises with beach bars and DJs. Yet it’s not all hedonism-wander to the Heart-Shaped Mountain Viewpoint to see the bay’s luscious curves from above, and you’ll agree that Samui’s wild beauty still wins out over its buzz.
