Koh Tachai
เกาะตาชัย
A remote island in the northern Similan Islands, with snow-white sands and turquoise shallows that rank among the most beautiful beaches of the Andaman Sea.
Koh Tachai is part of Similan Islands National Park and lies in the northern part of the island group. It has fine white sands and primeval jungle, and the surrounding coral reefs are home to schools of fish, sea turtles and manta rays. In 2016 the island was closed for a time due to overtourism and coral damage. After reopening, the number of visitors allowed ashore each day was limited. Most Similan day tours and Surin Islands tours stop here on the way, and you can also book a dedicated Koh Tachai tour for about THB 3,000 to 4,000. Anyone prone to seasickness should take medication in advance.
