W 080° 12.690’ Key Largo, Fl. Carysfort Lighthouse marks the main body of the 4 mile long Carysfort Reef system. The lighthouse is the oldest functioning lighthouse of its type in the US, built in 1852. Carysfort Reef is named for the 28 gun frigate HMS Carysford, which ran aground in 1770. 13 mooring buoys surround the lighthouse, each marking a dive spot. Depth is 5fsw to 80fsw. The lighthouse lies 6 miles off of Key Largo. The visiblity and coral are magnificent. Carysfort Reef is one of the best developed reef systems in the Keys. Located ENE of the tower is "Carysfort Trench" (a.k.a., "Caryfort Wall"). The wall drops 65-80 ft. to a sandy bottom. 5 cannons from the 1800s rest in 15 ft. of water 1/2 mile to the north of the tower. 2 large anchors thought to be from an 1800s frigate rest in 30-40 ft. of water 400 yards NNW of the tower.
