Boat-access outer-pass reef with rich fish life and pelagic action.
Sea horse is a boat-access outer-pass dive in the Dumbéa area, with a rich plateau above the reef that falls away into a deep drop-off. The site is known for heavy fish activity on the plateau and pelagic encounters offshore, making it a classic New Caledonia pass dive rather than a sheltered lagoon reef. Subject to swell and current, it suits divers who are comfortable planning around changing conditions.
