Koh Bida Nok Dive and Snorkel Site


The best dive plan is to begin shallow in the south and slowly descend along Finger Reef Ridge.

You should see a steep decorated wall with brain and bubble corals eclipsed by gigantic sea fans.

Shark fans are regularly rewarded with sightings of leopard sharks, black tips, tuna, jacks, and whale sharks during the plankton season.

There are several unrestricted swim-throughs on the west side of the island with boulder formations and underwater rock structures creating stunning backdrops for the environment.

Take a careful look inside the cracks and rock crevices and you will find nudibranch, white-eyed morays, the eternally shy seahorse, pipefish and other captivating macroscopic creatures.
