Why dive here
With 165+ marine species recorded in the area - including humpback whales, sea turtles, sperm whales and whale sharks - Hulls Rock offers some of Mafia Island's richest reef diving. Water ranges 26-29°C, warmest February, March, April.
Hulls Rock on Mafia Island offers a good drift, a gentle ride over a reef that starts deep and slopes up. We usually drop in around 30-40 meters and let the current carry us, watching for blue-spotted rays tucked into the sand and the occasional turtle gliding past. The deeper sections have some impressively sized barrel sponges, while the upper reef, from about 18 meters shallower, is where you find the healthier corals and schools of fusiliers. Keep an eye out for the Gilded Triggerfish; it’s a bit of a local celebrity here. This site is a solid choice for divers who enjoy a relaxed drift and aren't chasing big pelagics, though the reef fish are plentiful.
