The barely submerged reef is a well-known shipping hazard (see King Cruiser Wreck) and is located less than a mile north of Shark Point. The Thai name for this site is Hin Jom which means underwater rock and although not as colorful as Shark Point, the site is famous for its vast fields of sea anemones that cling to every conceivable surface and swing and sway with the current.

The profusion of sea anemones and the nutrient-rich water are a magnet to a constant parade of reef fish seeking food and shelter. Enormous schools of tropicals, snappers, groupers and colorful clown fish, along with larger game-fish like tuna and barracuda as well as the occasional leopard shark can be seen here.
