Exploring the Waters Around Phi Phi
The Phi Phi Islands are renowned for their incredible biodiversity, making them a top destination for divers in the Phuket region. Among the various dive sites, Bida Nok stands out for its world-class diving experiences. On any given day, you might encounter a variety of fascinating marine life.
Marine Life to Discover
Some of the remarkable creatures you might see include Hawksbill turtles gracefully gliding through the water, and Leopard sharks resting on the sandy ocean floor. Blacktip reef sharks often patrol the area, providing thrilling encounters for divers. You might also spot cuttlefish displaying their mesmerizing colour changes or the vibrant red reef octopus blending into the coral.
Eels are plentiful here, with species such as the giant moray, the fimbriated moray, the white-eyed moray, and the zebra moray making their homes among the rocks and crevices. The area is also frequented by Kuhli stingrays, banded sea snakes, nudibranchs, seahorses, and squid, adding to the richness of the underwater environment.
The vibrant fish life around Phi Phi includes snappers, parrotfish, barracudas, wrasses, rabbitfish, scorpionfish, boxfish, and puffers. You may also see schools of trevally and tuna swimming by. For those with keen eyes, pipefish can often be found camouflaged within the coral and rocks.

A Dive Destination for All Levels
Phi Phi is suitable for divers of all experience levels, making it an excellent location for PADI courses such as the PADI Open Water Course, and the PADI Advanced Open Water Course. The combination of diverse marine life and stunning underwater landscapes offers an unparalleled experience for both beginners and experienced divers, ensuring unforgettable dives and opportunities to expand your scuba skills.
Advanced Dives
The cluster of dive sites including Anemone Reef, Shark Point, and the King Cruiser Wreck offers incredible marine life encounters. It’s common to spot Leopard sharks in these areas, alongside a stunning variety of fish such as multiple species of anemonefish, trumpetfish, and cornetfish. Occasionally, you may even encounter rare visitors like the spotted eagle ray and shovel nose ray.
Seahorses can be found at both Shark Point and Anemone Reef, although hiring a guide is the best way to locate these elusive creatures. Visibility at King Cruiser is often humorously said to be “spoiled” by the sheer number of fish in the area. The site boasts massive schools of Forster’s barracuda and snappers, and swimming through these dense schools provides a thrilling dive experience.
While these dive sites are not recommended for beginners, they are excellent for those pursuing courses such as the PADI Advanced Open Water Course and PADI specialties like Digital Underwater Photography, Nitrox, or Deep Diver.
