    StandoutExceptional marine biodiversity

    The wreck of the Mesna, a substantial steamship from 1917, now rests on Hakaufisi Reef. We’ve found her a fascinating dive, especially for those who appreciate a wreck with history. At 117 meters long, there’s plenty to explore, from the exposed portions of the hull to the superstructure that’s become a home for all sorts of reef fish. You'll often spot schools of snapper darting in and out of the metalwork, and the coral growth, while not as vibrant as a dedicated reef, adds a unique texture to the ship's skeleton. It's a great choice for divers interested in both maritime history and the resilient marine life that colonises artificial reefs.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
