Big Fish Country (Maratua Channel)
East Kalimantan · 5–30 m
A signature drift dive at the channel mouth on the north of Maratua island, famous for an enormous schooling barracuda tornado. Current sweeps divers along a colourful coral edge where, around 27 m at the channel entrance, grey reef sharks, blacktips, tuna and big jacks gather. One of the Derawan archipelago's standout big-fish dives.
