Insights of Similan Island

Did you know? Similan Island is considered one of the best diving hot spot in Thailand. It is in a shape of like an archipelago consisting of nine islands naming them, Ko Bun, Ko Bayu, Ko Similan, Ko Payu , Ko Miang (two adjoining islands), Ko Payan, Ko Payang and Ko Huyong with a completed expansion of another two remote island namely Ko Bon and Ko Tachai in which Ko Similan is considered as the most popular one among the others.

The islands were created by upwellings of hot magma during the Tertiary-Cretaceous period some 65 million years ago, then smoothed by glacial ice and the erosion by the sea. The coral reefs are about 5,000 years old and hence the oldest in Thailand. In 1982, the national park was established and now it is scheduled to become a  UNESCO WORLD HERITAGE SITE.

During 2004 when the tsunami hits, the islands and the underwater landscape was left unharmed as since the water was very deep around the islands.

High season in the Similans is from December until April, when the monsoon stays far away. The best period to visit is March, when the winds are calm and the water clear. The national park is closed from May 16 to October 15. Be sure to check out our packages and the end date of our Similan liveaboard trip.
