You step onto a longtail or speedboat as the morning light slices across the Andaman—palm-shadowed shorelines slip by and the engine’s hum sets the day’s rhythm. The highlight is the Emerald Cave (Tham Morakot) on Koh Mook: a low, dark tunnel that dares you to swim through, only to open onto a hidden sand pocket where water glows green and the cliffs cup a secret beach.
easy.
8 hours.
Suitable for most fitness levels; participants should be able to swim short distances and climb in/out of boats unaided.
Boat transfers vary by launch point and vessel—expect combined travel time (van + boat) within the 8-hour tour; individual crossings may be 30–90 minutes depending on route and sea state.
The tunnel is short but low; swimmers push or kick through and may need to submerge slightly—guides time entry for safe tidal conditions and assist when needed.
Children can join but must be supervised; infants should sit on laps during travel and children should be confident in water—check operator age restrictions when booking.
The operator may alter the itinerary or cancel for safety if seas are rough; refund/cancellation policy allows full refund if canceled at least 24 hours prior.
Trang’s islands are part of a broader Andaman karst chain; local fishing communities and rubber plantations on the mainland shaped the region’s coastal economy.
Coral reefs here are sensitive—practice no-touch snorkeling, use reef-safe products and follow guide briefings to minimize impact.
