Dive-site story
Located roughly a mile east of Key Biscayne, Emerald Reef features two primary patch reef tracts running parallel to the shoreline. The reef structure rises from a sandy seabed with spur-and-groove formations, populated by brain corals, sea fans, and elkhorn coral outcroppings. Its shallow profile and proximity to Miami make it a favored spot for training dives, afternoon charters, and snorkelers exploring the northern extent of the Florida Reef Tract.
Extensive sea fan gardens and brain coral formations across shallow patch reefs
Frequent resting nurse sharks tucked beneath limestone ledges
Clear sand channels between reef spurs ideal for macro photography and fish identification

Seasonality
