Hol Sulamadaha - Halmahera

Maarehaa Kandu, over on the eastern side of Vaavu, is a channel dive that really delivers on the shark front. Thanks to its protected status, the grey reef sharks gather here in serious numbers. We’re talking over a hundred when the conditions are right, often with silver tips schooling alongside them. It’s a proper drift, so you’ll want to be comfortable with some current, but the reward is a spectacular show of apex predators in their element. Visibility hovers around 25 metres, giving you a clear view of the action down to the 30-metre mark.
