This dive site is sometimes called the best dive site in the world and it is a great hammerhead shark spotting dive site and is made up of a large boulder or rock that descends into the water, surrounded by a sandy bottom. Given the high chances of spotting large groups of hammerhead sharks, it is clear why this is one of the most desired dive sites in the world. This has been named Darwin’s Rock after the nearby island also called Darwin Island. The dive site is not very protected and so the conditions of the dive can be very rough with changing currents, surges, and large waves. For this reason, only experienced divers should attempt this dive.
The water here remains warm throughout the year and ranges from around 22 degrees to a very comfortable 27 degrees. The currents here are strong and come from the south-east, although they sometimes come from the North. The currents are then split by the rock arch.
The main attraction of this dive site are the hammerhead sharks that swim around in small to large groups. Many dive photographers visit this dive site to capture the amazing site of groups of hammerhead sharks that appear to be swimming in unison.
The sharks are attracted by the resident King’s angelfish that inhabits the rock arch. These act as cleaners turning the entire area into a cleaning station for these amazing sharks. The angelfish clean the sharks in groups and each hammerhead will have a number of angelfish eating the skin parasites off them at any one time. Jacks also come to be cleaned by the same process. Other fish found here include tuna, rainbow runners, snappers, mackerels, and often smaller reef fish that form tight fish balls. Dolphins and sometimes whale sharks are spotted out in the deep blue of the ocean.
