Located north of Koh Nang Yuan, Green Rock consists of several interesting rock formations with small caves, crevices, short tunnels, and swim-throughs worth exploring. There is an interesting night dive: the triggerfish secure themselves in the smaller crevices for the night and the parrotfish sleep in their cocoons while the nocturnal community comes to life.

When to go

Diving is available all year long, with the water temperature ranging from 25-29C/77-84F. The high season is from February to September.

What to see

Some of the marine species are grouper, blue-spotted stingrays, yellowmargin triggerfish (can be aggressive, especially if protecting their nests during the spawning season), parrotfish, and green and hawksbill turtles.

    UV Night Dive

    UV (ultra violet) SCUBA is a relatively new discipline. Scientists have discovered that under certain light wavelengths some species of marine species exhibit a phenomenon known as fluorescence, where the coral and fishes themselves appears to glow in crazily bright colours. Corals that normally appear dull brown in the daytime or under white light can take on vivid rainbow hues. Join us for one of these disco-tastic adventures and using our special blue light torches and funky visors you’ll see a magical array of psychedelic colours- fluorescent oranges, blues, yellows, greens, reds and purples. With glowing coral, sponges, fish, shrimps, crabs and other sea life, you won’t be disappointed. By the way, this is not bioluminescence that you see on some night dives, it is only visible using the blue light torches and mask filters. The phenomenon of coral fluorescence is still full of mystery and the reasons why certain coral fluoresce are to this date unknown, which we think just makes it even cooler! Whether you are an advanced scuba diver and want to experience the deeper UV ‘trip’ or simply want to snorkel and see this amazing spectacle from above, we guarantee you won’t be disappointed. Either way it will be a fun, memorable experience. All sessions are led by our professional, highly experienced, PADI & SSI diving instructors and we maintain maximum group sizes of 4 to ensure your safety and enjoyment. You must be at least Advanced already, or at minimum have prior experience of night or limited visibility diving.
