Coffins Patch

Six separate patch reefs to roam inside one preservation area

Coffins Patch is a cluster of about six patch reefs off Key Colony Beach, protected as a Sanctuary Preservation Area and among the best shallow sites in the Middle Keys. The reefs bottom out around 9 m (30 ft), and the usually minimal current makes it an easy, unhurried reef dive for snorkellers and divers alike.

Also known as Coffin's Patch.

The dive

The larger coral heads top out 1.5 to 3 m (5 to 10 ft) below the surface, over sand dotted with boulder and brain corals, sea fans and gorgonians. Schools of blue tangs, sergeant majors, angelfish and parrotfish swim around the coral, stingrays glide over the sand and nurse sharks rest on the bottom. There is usually minimal current, so it is easy to stay with the group and near the boat.
