Koh Tao Diving

Koh Nang Yuan

The small islet of Koh Nang Yuan is connected to Koh Tao by a thin strip of white sand and is surrounded by several charming dive sites. It's an area for relaxed and easy diving and is also a very popular place for snorkelling as there are plenty of reef fish.

Green Rock is a big boulder formation located on the north west of Nang Yuan Island. The dive site starts at about 1 metre below the surface and goes down to a depth of 30 metres. Green Rock has an impressive number of swim-throughs and overhangs which are the highlight of the site where you can expect to see moray eels, blue-ring angelfish, blue damselfish, groupers, batfish and sea snakes. It is also infamous for rather aggressive yellowmargin triggerfish and titan triggerfish.

Nang Yuan Pinnacle is located between Koh Nang Yuan and Koh Tao and is like a miniature version of Sail Rock. It is only a few fin kicks away from the eastern coastline of Koh Tao and starts at just 2 metres below the surface. There are many interesting boulders with nooks and crannies to explore here, and several swim-throughs. Moorish Idols, angelfish and oriental sweetlips are some of the common inhabitants. Also keep an eye out for octopus hiding in the rocks and cuttlefish.

Twins is just south of Koh Nang Yuan. It is a a similar site to White Rock on Koh Tao and is actually 2 rock reef patches starting at 6 metres and going down to 18 metres. There are lots of anemones here with their resident families of clownfish.
