Hin Daeng is a huge rock that protrudes three meters above the water's surface and descends over 60 meters to produce an extreme vertical drop. Soft corals and sea fans grow on the wall. It is possible to swim along two ridges that descend 40 metres or more leading lots of soft coral and large schools of fish. Marine life includes Needle Fish, Long Toms and Barracudas. The site is only suitable for advanced divers.
