This dive site is just off the northern side of Similan Island #9. The site mainly consists of big boulder formations, but closer to the island, at more shallow depth there are gardens of hard coral and bommies.
The boulder formations reaches up to 10 meters from the sand bottom at 40 meters . There are lots of beautiful soft corals between the rocks, look out for Banded Sea Snakes and shoals of Snapper.
In the deeper part of the dive look out into the blue for a possible shark or two, and in the shallows closer to the islands, look out for turtles. There can sometimes be a strong current in the deeper area, but there are plenty of boulders to give you shelter.
