Koh Tachai

Dive Location:  40km south of Koh Surin Tai.
Depth: Average 22m / Maximum 30m

This submerged plateau is divided into three reefs, each dominating a different depth with different structures and reef inhabitants.

Off the island’s southern point, two submerged pinnacles stand proud of many large boulders and smaller rocks, providing great swim-throughs. This, the southernmost area of the site, is part of the deepest of the three reefs, ranging from 25m to 30m. This section is a fairly reliable spot for catching glimpses of manta rays and whale sharks which both frequent the area.

The second, or central, section of the reef is slightly shallower and is constructed mainly of hard corals and large rocks, around which schools of spadefish – such as pinnate batfish – are tended to by common cleanerfish. Clinging to the rocks are gorgonian sea fans, featherstars, colourful crinoids and areas of carpet sea anemones. Large bullethead parrotfish and even larger Napoleon wrasse share these waters with moorish idols, schooling bannerfish, juvenile snappers and a variety of triggerfish, including titan and orange-striped.

The third and shallowest section of the site sits in 12m. Here you will encounter many Indian lionfish amongst backdrops of gorgonian sea fans and giant clams. Other schooling fish life includes batfish, sweetlips and juvenile yellowtail and chevron barracuda.
