The Similan National Park includes nine densely wooded islands fringed with rocky outcrops and gorgeous beaches of fine sand.
It's a great place for both diving and snorkelling in a pristine aquatic environment.
Touring by speedboat allows you to reach the Similans (in the Andaman Sea north of Phuket) in 90 minutes, providing lots of time to explore the underwater scenery in one of the world's premier dive sites.
