About this site
Langkoi Rock is a pinnacle in the south of Komodo National Park, in Indonesia, and the best site in the park for scalloped hammerhead sharks. It is only reached from liveaboards in the south.
Hammerheads gather here in the cooler southern water from July to September, and schools of 5 to 30 or more have been reported on good days. Dives often start at dawn in water of about 22°C. Divers descend to 25 to 30 metres on the deep edge of the pinnacle and hold position, scanning the blue for 20 to 25 minutes while the sharks pass at the edge of sight.
Advanced Open Water certification is needed, and a 5 mm wetsuit because of the cold. Grey reef sharks, whitetip reef sharks and manta rays are also recorded here.
