Hin Gong Dive site is a good dive site for exploring boulders and coral formations and there is a lot of marine life to spot. This wall dive site is located within the Surin Islands National park and has a maximum depth of around 35 meters, going up to about 15 meters. The site is made up of a pinnacle that is made from granite that sits on the sandy bottom. Visibility here can be very good and can reach up to 30 meters on clear days. The water on the surface can be quite choppy though as the winds can pick up causing surface waves. The marker buoy is useful as a guide to spot the location of the dive site.

The pinnacle is a boulder formation that descends down and is then surrounded by many smaller boulders. There is a smaller pinnacle to the east of this boulder that can be reached if the current is calm and is definitely worth an exploration. On both of the pinnacles, many swim throughs, small holes, caves, and caverns are great exploration points for divers. Sometimes nurse sharks can be spotted in these nooks and crannies.

Divers can easily spot the many resident long fin batfish, five line snapper, neon fusiliers, and many different types of Wrasse. Manta rays, mangrove stingrays, and eagle rays have been spotted on this dive site. There are many different lobsters, crabs, and shrimps and so this makes for a great night dive.
