Similan Islands perfect for diving and snorkeling


This chain of nine beautiful islands off Thailand's west coast are the jewels of the Andaman Sea! Declared a national park in 1982, they are famous as one of the world's best dive and snorkel sites. From Khao Lak, you can dive and snorkel these islands with a day trip on board MV Chai Yo.

Day trips to Similan Islands depart every Monday, Tuesday, Thursday, Friday and Saturday.
Sunday day trips go to the islands of Ko Bon and Ko Tachai.
This trip is perfect for certified divers!

Non-divers (snorkelers) have the option to step on the beach on Tuesday, Thursday and Saturday. The Sunday trip is better suited to good swimmers, with a minimum age of 12 years because of the strong currents often experienced at Ko Bon and Ko Tachai.

The best conditions are November to April. Non-diving guests on board MV Chai Yo receive maximum attention with a professional snorkel guide.
