About Umma Gumma
Umma Gumma is a rocky Grande Island reef with a clear line of outcrops and sand patches that makes the dive easy to read. The south side forms a short wall and the north side rolls into a boulder slope, so route choice changes with current and sea state. It suits calmer-day boat dives and rewards slow scanning of the rock gaps. Expect patchy coral, snappers, groupers, barracuda, and other mixed reef fish.
