Ton Sai is a beach near Krabi in Thailand, offering a combination of inexpensive accommodation and great rock climbing routes that make it popular with both backpackers and climbers alike. Compared to neighbouring Rai Leh and Ao Nang it's relatively rough around on the edges; in particular, the beach gets unsuitable for swimming and becomes quite rocky as the tide goes out. But this only happens for about ten days every moon period. The rest of the time the beach is suitable for swimming.
