Alligator Reef

The lighthouse tower at Alligator Reef marks a very large reef structure just offshore of Upper Matecumbe Key. Depths range from a shallow 8 feet to just over 40 feet. The tower, erected in 1873 is easily spotted from shore, only 4 miles from Indian Key. In 1825, the USS Alligator schooner "discovered" the reef here when it ran aground.

This popular reef is alive with fish, from blue tangs and yellowtail snappers to damselfish (they'll try to nip you if you get close), butterflyfish, parrot fish, schoolmasters and grunts. You might find a yellow stingray hiding in the white sand bottom, or the occasional flounder.
