Sometimes referred to as Hin Rap, this dive site is located within the Surin Islands National Park. Hin Kop is an interesting dive site that goes to a maximum depth of 30 meters. The dive site is made up of a small formation of rocks and a shoal, which is located a few meters from the rock. The top of the dive site is around 5 meters. The current is normally very mild and given the conditions, the dive site can be completed by divers with all levels of experience. Visibility can be excellent reaching 30 meters and so divers can see all the way to the bottom of the dive site.

As there are many scattered boulders forming archways and small cavers, divers can spend time exploring the rock formations, looking in the nooks and crannies to find smaller crustaceans and reef fish.

Like other dive sites in the area, the fish life is very good and divers can find marine life in abundance. These include puffer fish, lobsters, and crustaceans amongst the boulders, eels hiding in nooks and crannies, angelfish, lionfish, and butterfly fish. There is a good chance to see larger marine life with turtles and sharks being quite common.
