Scuba is the strongest independently supported in-water activity in the Hienghene circuit. Babou Cote Ocean, based in the Koulnoue tribe, advertises certified reef dives, training and one-on-one introductory dives with an islet entry. New Caledonia Tourism singles out the Cathedral for dramatic gorgonian-covered drop-offs and fissured rock, including tunnels that should not be entered without appropriate training, conditions and an explicitly guided plan. Babou describes most of its regular exploration as around the 20 m range, not a general promise of deep walls. Ask for the precise site, current sea state, certification equivalency and equipment before booking. Local diving | Cathedral site | Discovery dive
