Phi Phi Dive Sites - Koh Bidah Nok

Depth: 0-30m

Current: Mild-Moderate

Experience: Beginner

"Outer Father" is a small limestone cliff islet, 2 kilometres south of Phi Phi Leh. It is Phi Phi Islands' best dive site, due to its great diversity of marine life and is often visited on Thailand liveaboard cruises.

Koh Bida Nok is characterized by steep precipices, caves, swim throughs and underwater crags. There is a small underwater bay at the southern side of the Island made up of a reef slope and rocky floor that starts at 6m and ends in a sandy bottom at 20m. a vertical swim through on the southwestside of the island, not to be missed.

One side of this island offers shallow hard coral reef and on the other side the more experienced divers will find a wall with soft coral down to 30 meters. Features lots of marine life like Leopard sharks, Turtles, Morey Eels, Lionfish and Pipefish. There is always a chance for Manta Rays and Whales sharks and this is a dive not to be missed.
The west side of the island offers spectacular diving, with a finger reef at the south. Follow this out and look in the sand for stingrays and leopard sharks, which are often found sleeping there during the day.

Hollows in the reef offer chances to find ghost pipefish and Jenkins cleaner pipefish, be careful though many lion fish also seek the darkness of these areas.

Look away from the reef for huge schools of barracuda, trevally and mackerel. On the walls keen eyes can spot many different nudibrachs and some seahorses, also look under ledges and outcrops for bamboo sharks hiding.

At the end of the dive head to the shallow water, this is where the black tip reef sharks patrol looking for food, they are very fast and shy of divers so keen eyes are needed.
