    Juani South is where Mafia’s fringing reef truly shines. It’s a gentle slope down to about 20 meters, blanketed in corals that often give the whole place a soft pink and purple glow – really quite pretty. We’ve had some lovely drift dives here, especially when the current is mild, letting you glide past schools of fusiliers and the occasional giant trevally. Keep an eye out for the big green turtles; they’re regular visitors. Visibility averages 13 meters, so while not always crystal clear, it’s usually enough to enjoy the reef's subtle beauty. It’s a good spot for a relaxed dive, suitable for most experience levels.
