The reopening drew large crowds of eager domestic and international tourists to the Andaman Sea’s celebrated archipelago.

To preserve the area’s ecological balance, authorities have implemented a strict daily cap of 3,850 visitors and are urging all guests to cooperate in keeping the islands clean.

Tourists Head to Similan Islands Before Closure

The Similan Islands, consistently ranked among the world’s top marine destinations, now officially comprise eleven islands following the recent inclusion of Ko Tachai and Ko Bon within the national park boundaries. The annual monsoon closure from May to October is a critical conservation measure that allows coral reefs and marine life to recover from the impacts of tourism.
