Sea Turtles at Similan Islands

The Similan Islands offer the most accessible sea turtle viewing in Thailand, with hawksbill and green turtles sighted on 92% of snorkeling trips. Hawksbills, averaging 25 years to reach maturity, are 30% more common here than at any other Thai reef. Green turtles can weigh up to 190 kilograms, dwarfing the typical 110-kilogram average for Indo-Pacific specimens. The crystal-clear visibility, often exceeding 30 meters, makes every encounter feel intimate and personal.
