Chocolate Flow is a boat-access wall dive on Horsburgh Island with a coral-rich,
Chocolate Flow is a boat-access wall on the western side of Horsburgh Island in the southern atoll. The site is defined by a broad Montipora stand on the wall and a reef top with hard and soft coral cover. The profile is best approached by working the deeper section first, then easing shallower to finish on the reef top. It is a planning-sensitive dive where profile control and a longer safety stop matter.
