Bida Nai

This small island rock is located one kilometer south of Phi Phi Ley island. Similar to its sister island "Bida Nok" only 200 meters away, Bida Nai consists of sharp limestone cliffs, with no beaches or inhabitants except for the Brahmini Kites, Reef Egrets and Frigate birds. Should you decide to swim around the island it would take you only about one hour it's that small.

Points of interest?
* Fantasy reef is an outcrop of reef separated south of the main island by a narrow sandy divide. Here is a great opportunity to find leopard sharks sitting on the bottom or Barracudas patrolling over the mount.
* Another group of rocks south west of Bida Nai have a very interesting swim through. Pipefish and bamboo sharks are found in here while leopard sharks like to patrol around the rocks when they are feeling frisky.
* The north of Bida Nai has a spectacular wall covered with seafans and glass fish that are surrounded by trevallies hunting the smaller fish.

Bida Nai topography?
The reefs are fringing and range from gentle slopes to walls with occasional outcrops of rocks. Large fields of acropora corals on the south side, fields of sea anemones in the shallows and heavily populated wall on the north face.
