Dive Site Overview

Dominating the underwater landscape at Milimani South are ancient hard coral formations, rising dramatically from a maximum depth of 22 meters (72 feet) to just below the ocean's surface. These towering structures create an intricate reef system, offering an engaging dive experience.

The site is well-regarded for its drift diving opportunities, where currents can transport divers along the extensive reef. A notable feature is a resident cleaning station, a hub of activity where divers might observe a moray eel and Jenkins stingray receiving services from cleaner shrimp and wrasse. This dynamic interaction provides a glimpse into the ecosystem's intricate food web.

Beyond the larger residents, the reef pulses with diverse fish species, ranging from tiny anthias to sizable giant groupers. Divers also regularly encounter various schooling fish and more unusual sightings like leaf and crocodile fish.
