The engine cuts through a glassy Andaman morning and the horizon opens into pale coral islands—white sand and granite boulders rising like worn sculptures. On a full-day snorkeling run from Khao Lak you trade the mangrove flats for open sea, hopping by speedboat between Similan islands where surf and current sculpt the shoreline and fish dart through sunlight.

Respect the reef
Do not stand on or touch coral, and swim with a slow kick to avoid accidental contact—guides will brief on proper snorkeling etiquette.
