StandoutExceptional marine biodiversity

Corinne’s Reef is a site we always try to fit in when we’re on Mafia. We’ve had some truly fantastic dives here, especially when the light hits just right, illuminating the seagrass beds. It’s shallow, maxing out at 16m, which means plenty of bottom time to really soak it all in. What makes it a standout for us is the variety you find in such a compact area. You’ll drift over gentle corals, spotting those bigspot rockcods tucked into crevices, then suddenly the reef gives way to these expansive seagrass meadows. We often find green turtles here, lazily grazing, and we’ve seen some huge rays settled on the sand, almost blending in until they decide to glide away. The schools of beautiful fusiliers are often so dense they cast shadows over the reef, and it’s a site where we frequently spot blackside hawkfish perched on corals, watching the world go by. Keep an eye out for banded tobies and blackbar filefish, too. It’s a site that rewards slow, careful exploration rather than a frantic dash, perfect for photographers or anyone who just wants to relax and observe.
