The top of the reef lies at a shallow 3m (10ft) on the island side and inclines down to the sandy bottom, which is found at 12m. The coral is undamaged, and bigeyes and squirrelfish abound. There are varieties of lionfish and turkeyfish, and dense shoals of yellow-striped snappers. Large parrotfish feed off the coral, but not many other big fishes are present. As the name suggests though dolphins are often in the close vicinity of the reef.
The entire area covered by this dive falls within the Kisite-Mpunguti Marine National Park and Reserve, so park fees are payable before entering or diving.
Slightly to the southeast of Outer Mpunguti Island.
Generally clear and calm during the diving season, and also diveable in fair weather and during the rainy season.
