Ko Phi Phi
Like her sister island Bida Nok right next to her, Bida Nai is one of the picture perfect steep-cliff rock formations which make the area around Ko Phi Phi so beautiful. The shape of the island above the water pretty much also describes the shapes found under the surface – quite steep on the northern side and more sloped in the south.
In size Bida Nai is slightly smaller than Bida Nok and it is possible to dive around the island in a full hour dive. However it is not recommended to be pressed for speed with so much to see: turtles, cuttlefish, schools of snappers and sometimes even leopard sharks. Just south-east is an underwater rock formation called Fantasy Reef which is nicely framed by staghorn coral patches.
