Milimani South is a Mafia Island reef dive named for coral 'mountains' that rise from deeper water almost to the surface, making the site feel more like a chain of towers than one flat reef slope. Divers usually work along these hard-coral formations, watching the blue between pinnacles for schooling trevally and snapper while turtles and a resident wrasse often turn up close to the reef. Planning is straightforward but not trivial: it is a boat-access site with enough relief and occasional current that guides usually treat it as an intermediate reef dive rather than a first-timer lagoon stop.
