Koh Bida Nai diving site refers to the smaller of the two Bida islands (together with Koh Bida Nok). You can easily dive or swim with snorkel around the island in one hour providing that the current isn’t strong. In the little kind of bay sometimes Black Tip Shark are patrolling the area and are easy to be spotted together with Pharaoh Cuttlefish and Reef Octopus.

The south of Koh Bida Nai Diving Site

is a beautiful coral garden sloping to 18m where we can 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’s 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.
