Koh Bida Nok


Just south of Koh Phi Phi Ley is one of Phuket’s best dive sites by day trip, Koh Bida Nok. It is a small island, with stunning limestone cliffs, a shallow, sandy bottomed bay, rocky outcrops, wall diving, caves, swim-throughs and a huge diversity of marine life – this site is not to be missed.

Koh Bida Nok Information

  • Time to dive site: 2.5 hours by dive boat
  • Diver level: Beginner to advanced
  • Currents: Mild, occasionally strong
  • Depth: 5 – 28m

The deepest point around Bida Nok is found on the west side of the island which slopes down to depths of almost 30m. Travelling north, the site becomes a wall dive, with a cave at 20m on the north-west corner; bring along a torch so you can look inside. The east coast slopes away more gradually, with rocks and hard and soft corals to explore at between 10m and 20m. The south side of the island has a small bay with a colourful coral garden at 6 – 12m, perfect for all levels of diver. The island is too large to circumnavigate in one dive, so check the current, which usually runs north-east to/from south-west.

A whole array of sea life can be seen at Koh Bida Nok - crustaceans, beautiful gorgonians, moray eels, bubble coral, schools of smaller reef fish, cuttlefish, octopus and squid. Bluefin trevally and tuna can be seen circling the smaller species, hawksbill turtles graze in the shallows, black-tip reef sharks cruise along the east side, and even mantas and whale sharks have been known to visit this spot.
