    Sombrero Reef

    Admission included

    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.

    Crew was great! The boat was clean, comfortable, well maintained and safely operated. We look forward to going out with them again in November when we are back in the Keys.
