    StandoutExceptional marine biodiversity

    Lulu Deep, off Mafia Island, definitely delivers for those seeking a bit more zing. Starting around 18 metres, you’ll find yourself navigating a series of steep coral walls and sandy channels, all dotted with vibrant coral bommies. We’ve often drifted past shoals of surgeonfish and fusiliers here, so thick they almost obscure the reef, and it's a solid spot for spotting larger pelagics – barracuda and trevally are frequent visitors, and we've certainly had more than a few close encounters with green turtles. It's an advanced dive, for sure, best suited for divers comfortable with potential currents and deeper profiles, but the reward is a genuinely dynamic reef full of activity.
