Dive & Snorkel Koh Bida Nok

Koh Bida Nok is the southernmost island in the Phi Phi group, a favourite dive spot for many visiting the Phi Phi islands.

The northern part of this limestone island drops down to around 32m - 35m, offering great wall diving on both sides of the island as you move further south, where the reef becomes more shallow, eventually finishing in the small lagoon at the southern tip of Koh Bida Nok.

The eastern side of Koh Bida Nok is often bathed in sunlight, and as you move south, the wall become less steep and the corals more abundant. Giant moray eels, turtles, lionfish, schools of snapper, hunting jackfish, nudibranchs, sweetlips, barracuda and sea snakes are often spotted on the north eastern part of this dive site.

As you come between Koh Bida Nok and Koh Bida Nai, the coral bommies stretch out into the blue, almost connecting the 2 islands, and it is here that zebra sharks and stingrays are often found in the sand.

The west wall of the island runs deeper than the east side, with fantastic walls, and large coral outcrops lying just a 10 - 15m from the wall in deeper water down to 30m where you can sometimes spot nurse sharks and bamboo sharks hiding under the corals. It's not unheard of to spot manta rays and whale sharks cruising past on the western wall of Koh Bida Nok, and the shallows are home to blacktip reef sharks and octopus.

The colourful lagoon rises from 14m into the shallows, where juvenile black-tip reef sharks are often found in the shallows, together with soldier and damselfish, parrot fish, butterfly fish, colourful wrasse and crocodile needlefish patrolling the shallows.

There is also a cave on the northern part of Koh Bida Nok, however we strongly recommend that you do not enter this narrow passage without the proper training in cave diving techniques, accompanied by experienced professionals.

Koh Bida Nok is often combined with diving or snorkleing at Koh Bida Nai or Hin Bida.
