About Third Reef
Third Reef is one of Collier County's offshore artificial-reef piles near Marco Island, built from concrete blocks and culverts and spread across a broader reef field. It is the kind of Gulf dive you plan as a boat day for structure, goliath grouper, and fish life rather than for dramatic depth.
