Bida Nog Phi Phi Thailand

Along with its sister island, Bida Nai, Bida Nok (sometimes spelt Bidah Nog) is one of the best dive sites local to Koh Phi Phi. A sheltered bay to the south of the island provided a perfect shallow area to drop divers and begin the dive. Even in this shallow bay it's possible to encounter Zebra Morays, Stingrays, Leopard Sharks, Turtles, Scorpionfish and even a Whaleshark!  Descend in the bay and continue in either direction, current allowing.

To the east, pass some sunken boulders and see some impressive coral formations, teeming with small fish and marine life. Stay shallow on the eastern slope and at about 6 metres it's normal to see a few Blacktip Reef Sharks. If you approach too fast or get too close they will disappear into the depths. Leopard Sharks sightings are more normal than not at this site - so it would be unlucky not to see at least one. There is a massive amount of life at this site, partly due to Koh Phi Phi being protected as a National Marine Park. Of course, there is still much illegal fishing that goes on here, but the limited policing it receives makes a huge difference.

On the northwestern edge of Bida Nok, there is a sheer wall that drops down to 32 metres. The wall is blanketed in purple, orange and white soft corals from about 5 metres downwards. At the foot of the wall there are many huge boulders, nooks and crannies affording lairs and homes a spectrum of marine critters. Occasionally Whalesharks pass by, so be sure to keep and eye out into the blue periodically. Indeed, Whaleshark sightings are increasing annually, which can only be a sign that due to eco tourism in places like the Philippines, and other countries in South East Asia, fewer Whalesharks are being needlessly slaughtered for their fins. This is a practice that simply must be stamped out worldwide. In particular, during the whole of 2008, Whalesharks were spotted at the Bida Islands almost every week.

All in all, if you're headed to Phuket or Koh Phi Phi, Bida Nok is a must for your dive itinerary along with Bida Nai. Also, expect to find Frogfish, Ghost Pipefish and even a Seahorse. Trips run daily from Phuket and it's also possible to arrange over night liveaboards to the Phi Phi Islands. Alternatively, day trips can also easily be arranged from Koh Phi Phi.
