About Castle Rock

Castle Rock is an underwater pinnacle in the north of Komodo National Park, near Gili Lawa Laut. It rises to about 4 metres below the surface and drops to around 30, and strong currents around it draw large numbers of fish.

The currents carry nutrients that feed reef sharks, giant trevally, tuna, barracuda and big schools of fusiliers. Divers usually start up current of the pinnacle, drift down along the reef and hook in at the best spots to watch.

Among the gorgonians and sponges there is macro life too: nudibranchs and pygmy seahorses. Eagle rays, turtles and Napoleon wrasse are on the list of regular sightings.

Castle Rock is for experienced divers comfortable with strong currents, negative entries and depth. Its location and conditions make it a regular on liveaboard trips.
