Bida Nai is a popular dive site around Phi Phi Island and a must for any scuba diver visiting Phi Phi. Like its larger neighbor, Bida Nok, Bida Nai is a limestone cliff islet with similar topography and equally diverse marine life.

Descent is often down a mooring to the top of a small boulder formation and to the first of two swim-throughs, depending on your groups experience your dive guide will lead you through or around. You wouldnít see the large gap in the rock unless you knew it was there as itís almost always completely filled with masses of small silvery glass fish that disperse as you begin your swim-through.

Keep a close eye on the rock walls just inside the swim-through as itís a favorite spot for seahorses and ghost pipefish plus colourful nudibranchs. Care is needed with buoyancy as Bearded scorpion fish like to sit on the bottom.

Swimming east around the island you pass small coral bommies and a colourful sloping wall covered with anemones with resident clown fish and porcelain crabs. Crossing a large field of Stag-horn coral itís common to see resting Leapord Sharks (also known as Zebra Sharks because of the stripes across their backs as juveniles). The majority of the dive is often spent on an outcrop of coral known as Fantasy Reef made up of barrel sponges, sea whips and gorgonian sea fans and other hard and sort coral producing a perfect home for many of the Andaman Seas reef fish. Schools of Trevally and Jacks are also constantly feeding on the balls of bait-fish above the reef.

On your return keep a sharp look out for the black tip reef sharks that regularly patrol the sand at the outer edges of the reef particularly on morning dives. Black-tips are quite shy of divers so you generally only see them if they donít see you first. Closer in towards the main island is another long narrow swim-through. Emperor angelfish and Grouper are very common here. Look up to the surface and youíll see crocodile longtoms swimming above. Towards the end of your dive in the shallower water, look for pairs of cuttlefish performing colourful dances and Turtles gliding effortlessly without a care in the world. On you safety stop look out for Chevron Barracuda cruising by in search for its next meal from the smorgasbord of reef fish below.
