Hin Gra Dueng Pinnacle
A rock pile off Koh Rang that almost breaks the surface
Hin Gra Dueng is a pile of rocks on the northern side of Koh Rang whose top almost breaks the surface. It reaches far deeper than the shallow coral sites nearby, giving one of the bigger depth ranges in the Koh Rang group, and the water around it is often murky.
Also known as Hin Gue Dueng, The Pinnacle.
Where it is and how deep
11.8108° N, 102.3718° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The rocks rise from depths of up to 30 m (98 ft) to just below the surface, so the dive can range from the deep base of the pile to its shallow top. The water here is quite murky, and the deeper parts of the rock sit well past the 10 to 15 m of most Koh Rang dives.
