North Dry Rocks is better known as Minnow Cave as that is the main reason divers will dive at this dive site. It is an area of limestone ledges reaching the surface and creating great valleys in between with many fish and coral.
Minnow Cave is one of the top coral caves in Florida marked by several yellow Sanctuary Preservation Area (SPA) buoys and three N-lettered mooring buoys, located in the center of the reef.
