Koh Bida Nai diving site refers to the smaller of the two Bida islands (together with Koh Bida Nok) and providing the current is manageable, you can easily swim around the island in one hour.

The south of Koh Bida Nai Diving Site

is a beautiful coral garden sloping to 18m where we find pinnacles creating a playground of swim through’s, towards the southeast lies a large area of stag horn corals, that joins up with another rock formation which his name is  fantasy reef.

The north and west faces of the Koh Bida Nai Diving Site

are vertical walls to about 25m. The wall sections are covered with Gorgonian fans, sea whips and soft corals. This is a good place to find ornate ghost pipefish, sea horses and nudibranchs. Shoals of pelagics can be seen hunting out in the blue, and Black Tip Sharks are therefore regular visitors patrolling in the shallows.
