The speedboat cuts through warm Andaman water as limestone walls slide starboard and port, sunlight sinking behind jagged karst. You step aboard in Tonsai, hours ahead of the night, and watch the islands change color — Pileh Lagoon’s turquoise deepens, Maya Bay’s sand goes quiet, and Bamboo Island’s shoreline gleams under the low sun.

Wildlife
History
Phi Phi’s karst islands are uplifted coral limestone shaped over millennia; Maya Bay gained global attention after its use in the 2000 film "The Beach."
Conservation
Tours pay national park fees that fund management; seasonal closures (including annual Maya Bay restorations) aim to let reefs and beaches recover from high visitor numbers.
