This national park in Phang-nga Province 100 kilometers northwest of Phuket consists of nine desert islands whose natural beauty and incredible underwater vistas make them possibly the most loved dive sites in the Andaman Sea.

The Similans boast 25 world-class dive venues. They are famous for their dazzling marine life, warm, clear water and mild sea conditions. Visibility is usually between 18 and 25 meters and at times exceeds 40 meters.

There is a huge variety of wildlife under the water, with sites on the west of the islands open to the sea, and sites on the east fringed with hard coral. Larger marine animals that inhabit the waters around the Similans include whale sharks and cow-tail rays.

Several sites feature giant coral bommies, covered with soft corals and sea fans rising dramatically from the bottom. Out of the water, the virgin beaches and the flora and fauna beyond are breathtaking.
 

Despite the reputation of the the Similans, some pros argue that for sheer excitement, you can't beat Koh Bon. Divers to this small island 20 kilometers north of the largest Similan should, as they negotiate the vertical walls, be prepared for close encounters with leopard sharks. Here the corals come in unique rich hues; blue, yellow and turquoise. Koh Bon is also renowned for its high number of manta rays, especially at the end of the season in April and May.

A further 25 kilometres north of Koh Bon is Koh Tachai, with a stunning pristine beach straight out of fairytale imaginations. Koh Tachai is famous for its large sea creatures. Divers and snorkellers can expect to see whale sharks, leopard sharks and nurse sharks, as well as rays and hawksbill turtles. The waters around the island are teeming with all kinds of tropical fish and coral.
