Diver's Notes

Bida Nok means outer father and is a small but steep limestone island less than two kilometres south of Ko Phi Phi Lae. Like Ko Bida Nai, it has several distinctive underwater diving environments, which make it one of the best diving places in Thailand and with not without reason.

Most divers follow the same dive plan and start near a small sheltered bay on the south side of the island. From there it is a shallow gradually descending dive along a ridge named Finger Reef. Once you reach its edge around its south point you will find a steep wall which is decorated in vibrant anemones, brain corals, bubble corals and huge sea fans. The current picks up and brings several larger species such as tuna and jacks. The white sand is a very good place to spot khul stingrays and leopard sharks. Other sharks such as the black tip reef shark, bamboo shark and even whale sharks have been reported occasionally. Inside the cracks and crevices are nudibranches, moray eels, scorpion fish, seahorses, harlequin ghost pipefish and other macroscopic marine life.
