Sombrero Reef sits in the warm, shallow waters of the Atlantic off Marathon, Florida, marked by a towering lighthouse that has guided mariners for over a century. Beneath the surface, Sombrero Reef reveals a living mosaic of brain coral, sea fans, and darting tropical fish. The water clarity here is exceptional, making it a rewarding destination for snorkelers and divers alike.
