Koh Tachai (The Dome)

In contrast to the manicured feel Similan Island has to it, Koh Tachai feels 'wilder' with teems of schooling fish descending en mass to feed on the rich beds of corals. If the current is too strong stay on the line and watch as the Emperor Fish, Chevron and Great Barracuda, Yellow-tailed Barracuda and a variety of Trevally race around the site, while smaller fish including rainbow runners and Fusiliers zig-zag away from hunting giant Trevally, barracuda and tuna.

The navigation of the site depends on the current, but work your way around the edges, and come towards the center to shallow depths. Groups of Snapper can be found resting on the top of ledges, Octopus can frequently be seen amongst the corals. Various types of Anemone host Clownfish around the site.

Red-Banded Cleaner Shrimp work under coral ledges. Manta sightings are common and Whale Shark sightings are occasional. Frogfish, Ghost Pipefish and Juvenile Angelfish, Trumpetfish and Cube Boxfish can also be found by those with a keen eye. Work back to the mooring line for the safety stop.

Depth is from 12 meters down to beyond 35 meters. Experience level is intermediate to advanced due to the often ripping currents.

Very rewarding for the divers that dare...
