Getting there and around

Dramatic limestone towers, protected east-coast reefs and intimate day-boat diving.
Overview
Hienghene pairs the jagged Linderalique limestone coast and Brooding Hen rock with reef diving in the World Heritage-listed northeast New Caledonian lagoon. Divers typically stay in Hienghene village or near Koulnoue and arrange short local boat outings, rather than an overnight dive vessel. Babou Cote Ocean, based in the Koulnoue tribe, publishes guided exploration dives, training, introductory scuba, afternoon snorkeling near Hiengabat Islet, sightseeing boats and kayaks. The Cathedral is a named signature reef dive, but its faults and tunnels require a conservative, operator-led site plan. Hienga Islet's guided snorkeling trail is currently unavailable through Babou, and Tao Waterfall access is separately marked closed. Before paying, confirm boat availability, road access and local permissions. Operator services | Cathedral | Current snorkel status
