About this site
Cannibal Rock is a reef dive site located in the southern part of Komodo National Park, Indonesia, reaching from 5 m to a maximum depth of 30 m. It is accessible to all levels of diver, including those holding an Open Water certification, and is typically reached by liveaboard from the north, as its southern position makes it less convenient from shore-based operations.
The reef holds an unusually broad mix of large and small marine life, making it a site where wide-angle and macro subjects coexist. Trevallies and barracudas represent the larger schooling species, while bamboo sharks and scorpionfish are also recorded here. The verified species list extends to frogfish, nudibranchs, rhinopias, pygmy seahorses, crinoids, sea apples, reef sharks, and manta rays, with August to September cited as the peak period for bigger fish and December to March favouring macro encounters.
Conditions at Cannibal Rock include strong tidal flows and cold water, which are the principal hazards. Water temperature ranges between 20 °C and 25 °C depending on the season, and currents, though rated mild at the site itself relative to some of Komodo's more exposed locations, can still run strong with the tides. Visibility is generally good. The broader Komodo season runs April through November for the most consistent conditions.
