Green Rock


Short tunnels, Swim throughs, and the Trigger Fish pit, makes this dive site sound like it’s from an Indiana Jones Movie. The small tunnels vary in size and shape, and some can be a bit of a squeeze at times, but there are many larger swim through easily big enough for the faintest of hearts. Then there’s the Trigger Fish pit...

Looking like craters on the moons surface, the nests are clear to see, and act as a very good “keep out” sign. Although this is only really a problem during April, May, and June which is breeding time for the Trigger Fish. The rest of the year they are normally pretty tolerant of divers, and you may be lucky enough to see the not so common Yellow Margin Trigger Fish. Admittedly a favourite for the more adventurous diver, Green Rock does have its calm and peaceful side too.


With probably the biggest variety of nudibrach, and Flat worms (Spanish Dancers) in Koh Tao, it’s ideal for those underwater photographers to get a bit of macro action. With brightly coloured Parrot Fish feeding on the main pinnacle, White Eyed Moray’s tucked away in one of the many cracks, and Blue Spotted Rays hiding in the deeper water, time almost disappears on this site.
