About This Dive Site

Cannibal Rock: A Macro Paradise in Komodo's South

Nestled within the horseshoe-shaped embrace of Loh Dasami Bay, in the remote southern reaches of Komodo National Park, lies Cannibal Rock – a dive site renowned globally for its extraordinary macro life and vibrant coral gardens. This compact seamount rises from the sandy bottom, with its slopes topping out near 3 meters and plunging past 25 meters, reaching a maximum depth of around 30 meters. Divers will find every inch of this underwater pinnacle carpeted in a breathtaking display of crinoids, tunicates, and soft corals, bursting with fluorescent greens, yellows, and reds.

Diving Conditions and Certification

Diving Cannibal Rock is considered an advanced experience, and we recommend that divers hold an Advanced Open Water certification to fully appreciate its wonders. While the bay offers some shelter, currents at the dive site are typically moderate, though Komodo's dynamic waters always demand respect. One of the defining characteristics of this southern Komodo dive site is its cooler water. Divers can expect water temperatures to range between 22°C and 26°C, but be prepared for colder thermoclines, as nutrient-rich upwellings from the deep Indian Ocean can sometimes drop temperatures even further, occasionally as low as 19°C. We advise wearing an extra layer for warmth, such as a 5-7mm wetsuit with a hood, to ensure a comfortable dive.

Unparalleled Marine Life Encounters

Cannibal Rock is a true biodiversity hotspot, often hailed as one of the world's best macro dive sites. The cold, nutrient-thick upwellings fuel an explosion of invertebrate life, creating a vibrant ecosystem that macro photographers adore. As you explore, you can encounter a near-endless parade of assorted Nudibranchs and the site's signature vivid Sea Apples (Pseudocolochirus violaceus). Keep your eyes peeled for the intricate patterns of Fire Urchins (Asthenosoma varium) often hosting tiny Coleman Shrimp (Periclimenes colemani). The camouflage masters are also abundant here, with sightings of Giant Frogfish (Antennarius commerson), the elusive Weedy Scorpionfish (Rhinopias frondosa), and Leaf Scorpionfish (Taenianotus triacanthus). For those with a keen eye, the tiny and enchanting Pygmy Seahorse (Hippocampus bargibanti) can be found hidden amongst the gorgonian fans. Beyond the macro marvels, divers will also find larger marine life, including cruising Green Sea Turtles (Chelonia mydas) and schools of trevally in the moody grey-green waters.

The Origin of the Name

The intriguing name "Cannibal Rock" stems from local lore. It is said that the divers who first discovered this incredible dive site witnessed Komodo dragons engaging in cannibalistic behavior on the nearby beach in Horseshoe Bay, giving the site its memorable, albeit grisly, moniker.
