Pileh Lagoon

A long, narrow inlet on the east side of Phi Phi Leh, about 600 metres deep and walled by limestone cliffs around 100 metres high. The water is shallow, calm and turquoise over a sandy bottom; there is no coral inside the lagoon but snorkelling is possible near the entrance. It is part of almost every Phi Phi boat tour and is busiest in the late morning, so early or late visits are quieter. Covered by the national park fee.

Pileh Lagoon is on Phi Phi Leh, the uninhabited island 20 minutes by boat south of Phi Phi Don.
