About this site
Hin Kuak Ma, also known as Three Finger Reef, is a reef site located at Koh Rang, featuring a rock wall along its south side and a coral-covered slope on the back. The reef takes its name from three distinct coral "fingers" that extend from the structure, creating a varied underwater landscape suited to beginner divers. Maximum depth is 15 metres.
The south-facing rock wall gives way to a sloping, coral-covered backside, with the three finger formations providing shelter and habitat diversity across the site. Visibility ranges from 5 to 20 metres depending on conditions, and the site is accessible during the November to May season.
Marine life at Hin Kuak Ma includes eels, moray eels, nudibranches, stonefish, blue-spotted stingrays, blue-ringed angelfish, snapper, and Indian Walkman fish.
