Bida Nok the larger of the two dive sites that lay most southerly of Phi Phi Don, the Main Island in the Group.
It takes at least two dive to see this dive site in its entirety. Starting in the main bay which faces east there is a large sandy bottom at about seven metres -excellent for practising your dive skills.
Following the site south you will find a ridge following the ridge to about eighteen metres you can find Nudibranch, Octopus, Pipefish maybe even a sleeping Leopard Shark.
There is a drop off just over the ridge and this is where the action kicks off - it’s like walking into a Wild West saloon. There are several species of Trevallies with Tuna and Mackerels darting about on the hunt for food, you can see Spanish Mackerel even the odd Black Tip it’s wonderful.
Other Phi Phi Sites
Speaking of Black Tip Reef Sharks they cruise here usually preferring the shallower parts of the reef, they are quite a timid species and will shoot off if you get too close.
There is a large school of Yellow Snapper, and if you are lucky enough to have them give you a swim by it can take up to a minute for all of them to filter past you, it's beautiful. Also in this area, there are a few small caverns to explore, and it can get a little darker on this side so if you have a torch bring it
There is also a couple of very large Barracuda lurking, which can be quite spooky if you don’t see them first, as they can approach divers to see what’s going on.
Out on the sand, it’s common to find Blue Spotted Stingrays; also I personally have seen Cuttlefish mating here. There are turtles, coral banded Sea Snakes which will be hunting in the small nooks and crannies. These snakes are poisonous but never bother divers and only interested in small fishes that they have trapped.
There is so much to see on Bida Nok, and is a very popular dive site for every level of diver, no trip to Phi Phi Island would be complete without a dive here.
