Tham Phang (Collapsed Cave) Beach is far the most popular on the island. As the picture shows, it boasts canvas deck chairs and umbrellas, inner tubes, snorkels and masks, and kayaks for rent. A few meters inland you'll find a modest restaurant, bungalows, and facilities for a shower and change after your swim.

Samlor fare from the market area is about B80 each way, an expensive legacy from the days when the road was a very rough dirt track. It's worth extending the ride out to the end of the point where the cave is, and coming or going, ask to take the road over the hill by Wat Tham Yaai Prik, which offers some spectacular views.
