Snorkeling can be great fun and is actually better for viewing fish than scuba diving, as the bubbles from scuba divers can frighten the fish away. The options for snorkelling around Phi Phi are almost limitless. Try cave snorkelling on Phi Phi Leh or going on a shark watch. This is not as dangerous as it may sound, the sharks found in the waters around Phi Phi are small and are more scared of humans than we are of them.

Full-day and half-day snorkelling trips can be arranged at dive shops and tour operators around the Ton Sai area. Many island tours will usually include stops at popular reefs for an opportunity to view the coral.
