Peculiar animals such as the guitar shark, large octopus, and cuttle fish are commonly sighted here as well. Ko Bon and Ko Tachai are located between the Surins and the Similans and feature vertical walls, large sea fans of every shape and size, rays, and leopard sharks. These islands are normally visited on the way back to the Similans from either the Surins or the Banks. Most of these areas can only be visited by way of live-aboard dive boats. Day trips and shorter live-aboard are available from Phuket, Ko Phi Phi, Krabi and Ko Lanta.
Colorful crinoids adorn the wall and a wide variety of fish patrol the depths.
Shark Point lies about two hours to the east of Phuket and is one of the most popular day trips because of the colorful and prolific marine life found there. It is named after the friendly, approachable leopard shark, which can be observed on most dives. Although visibility varies, this is one of the most beautiful sites in the Andaman Sea. The Phi Phi Island group is also a popular day trip from Phuket and Krabi, but accommodation and dive centers are available on the island as well. Stunning scenery both above and below the surface of the sea and the tremendous variety of diving environments makes Ko Phi Phi one of the most visited places on the west coast of Thailand.
