First Reef
First Reef is a shallow Marco Island artificial reef with dense structure.
About First Reef
First Reef is a shallow Collier County artificial reef off Marco Island with concrete and boulder structure that quickly starts holding fish. It sits a couple of miles out from Caxambas Pass, so this is a boat run into compact reef patches rather than a long offshore push. Visibility is usually the limiting factor, but the short, structured profile makes it a practical local dive when you want easy route-finding and solid fish life.

Local Intel For First Reef
Community notes to help plan your visit.
Scuba Diving
Boat-access reef dive for new and returning divers who want an easy local profile and do not mind low visibility.
Freediving
Not a strong freedive choice because the reef is a boat-run structure with limited nearshore clarity.
Snorkeling
Snorkeling is not the main use case; the best structure and marine life sit below the surface.
