About Grecian Rocks
Grecian Rocks is a classic shallow Key Largo sanctuary reef with protected-water snorkeling, elkhorn and soft corals, coral heads, turtle grass, and a steady mix of reef fish. Boat tours use it often when nearby reefs are rougher, and the shallow crest can sit at or above the surface at low tide. Calm days give the best look at the reef structure.
