Koh Bida Islands Koh Bida consists of two small islands located close to the southern tip of Koh Phi Phi islands. These two beautiful islands provide a great chance of seeing turtles and sharks. Koh Bida Nok Bida Nok, the larger of the two islands, offers fantastic walls and reefs descending down to 28 meters deep. On its west side, this island is a natural habitat for a vast range of corals and marine life. On the east side, there are shallow reefs and plateaus just three meters deep where black tips can be regularly seen. Going to the south, there is a large bay area located where students can practice their skills, while going to the west, beautiful finger reef guides people down to where sting rays can be found in the sand. Octopus, turtles, sharks and many other big predator fish can be easily seen swimming out in the blue, while diving around this site. Koh Bida Nai Koh Bida Nai is a home to one of the most spectacular wall dives on all of our local dive sites. Starting from the west side of the island and following it to the north and north-east side, it is an ideal habitat for small reef fish, nudibranchs, shrimps and similar living things. Various schools of large predator fish can be seen hunting off the wall in the blue beyond as well. A fantasy reef is located on the south-east side of the island, starting at around 18 meters deep and ending at around 27 meters deep. This reef is home to an amazingly large quantity of lionfish. Large schools of fish such as barracudas, trevallies, and rainbow runners can be seen congregating here too. Also, there is a shallow sloping reef on the east side extending down to around 12 meters, which turned out to be a perfect place for students to undertake their skills training.
