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.
