Diving at the Similan Islands

Similan Islands

Dive Sites

Here are probably the most beautiful and diverse dive sites in Thailand, day trips and liveaboards to the islands are among the most popular worldwide. They consist of nine islands of granite rock with partially lush tropical vegetation, lapped by crystal clear water and lined partly with fine white sandy beaches. The islands stretch over 25 kilometers, like a pearl necklace, from north to south on the Andaman Sea and located 65 km off the coast of Phang Nga province. They were declared a Marine National Park in 1982.

The Similans are ideal for observing or photographing small fish by its enormous biodiversity of tropical reef fish. But not only small fish visit here, even Leopard sharks or White and Blacktip sharks are not rare also Manta rays and Whale sharks can be seen. You can visit the Similan Marine National Park from October to May on day trips or overnight trips, but you will find the best conditions from November to April.

Our dive and snorkeling day trips to the Similan Islands depart every Monday, Tuesday, Thursday and Saturday.
Dive day trips to Koh Bon and Koh Tachai take place every Wednesday & Sunday.

We bring our guests by Taxi to Tablamu where our comfortable dive boat MV Chai Yo is moored. We try to make sure that also our non-diving guests receive maximum attention, fun and safety.

Koh Tachai

Koh Tachai

Twenty-five kilometers north of Koh Bon, Koh Tachai has an offshore underwater ridge that runs perpendicular to the island. Known as "Twin Peaks" this is considered to be one of the finest dives in the Kingdom of Thailand and is famous as a place to see not only the more common species of corals, fans and tropical fish, but larger animals such as rays, leopard sharks, nurse sharks and hawksbill turtles. Whale sharks and Manta rays make an appearance on a regular basis.

A ridge runs between the two pinnacles, though the southern rock is the one most people dive on as there are two boat moorings there which makes it easier for divers to descend in a strong current. If you have the air and the current is not too strong, it's worthwhile swimming to the other rock which comes up a bit shallower. However, most of the time the current runs perpendicular to the ridge making a long swim tiring.

It's heaven for the fish, though; they hunt and dart around, coming very close to divers, making the diving here about as exciting as it gets here in Thailand
