Crater is a Florida Keys reef-wall dive built around a sandy pit and surrounding spur-and-groove coral. The appeal is an easy-to-read layout, broad coral structure, and a reliable mix of schooling fish and larger reef visitors along the edge. It is best treated as a boat-access recreational dive that rewards calm seas, light current, and a slow scan of the sand hole and reef rim.

Community notes to help plan your visit.
Scuba Diving
Best as a guided recreational scuba dive along the reef wall and around the sand hole. The site rewards a slow circuit and good buoyancy.
Freediving
Not an ideal freedive target. The reef wall and site layout are better suited to scuba than to breath-hold diving.
Snorkeling
Not an ideal snorkel target. The main structure sits below routine surface-viewing range, so scuba is the practical option.
