Long Set Beach lies along Cambodia's coast, in the stretch of the Gulf of Thailand near the country's southern islands. Coastal dive access in this part of Cambodia typically runs out from towns such as Sihanoukville or the islands offshore, like Koh Rong and Koh Rong Samloem. Divers here have reported banded sea urchins and black longspine urchins along the bottom, along with blackblotched porcupinefish, moon wrasse, and boring giant clams tucked into the substrate. Torpedo scad have also been spotted passing through, and viola land hermit crabs have turned up near the shoreline itself.
