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”.
