Greg's Wall Dive Site — Madagascar
About Greg's Wall
One of Nosy Be's signature dives, Greg's Wall is a spectacular vertical drop covered in a carpet of soft corals, sea fans and black coral trees. The wall starts at 10m and plunges beyond 40m into the abyss. Whale sharks are regularly encountered during the plankton-rich season from October to December, cruising slowly past the wall. Hawksbill turtles rest on coral ledges, and large Napoleon wrasse patrol the wall edge. The soft coral coverage is among the densest in the Indian Ocean.
