Carysfort Trench

Carysfort Trench: Coral reefs, caves, wreck scuba diving Florida Keys has it all with some of the clearest waters anywhere…

Carysfort TrenchCarysfort Trench is located to the North of the lighthouse and is in 25 meters (80 feet) of water. The coral reef has formed a rapid drop off down to the sandy bottomed floor.

This site is fish heaven! Schools of fish around every corner. A must dive for those people who like to see a vast array of colorful fish.

There are two points of interest in the area. Just ½ mile north of the lighthouse in 9 meters (30 feet) of water lays two 18th century anchors, and ¼ mile NNW of the lighthouse, 5 cannons lie in 5 meters (15 feet) of water. These shallow depths make these ideal novice diver confidence building dive sites.

  • The wall coral here is amazing with
  • Staghorn coral
  • Sheet coral
  • Brain coral, and
  • Large sponges

Carysfort Reef is named after the lucky frigate HMS Carysford. This twenty eight gun frigate HMS Carysford collided with the reef back in 1770 and was lucky to escape with minor damage and continue on her voyage.

This extensive reef is located in the protected northern section of the National Marine Sanctuary.

It is some 6 miles from Key Largo and as a result if you intend to go scuba diving Florida Keys, you will find this is one of the less frequented dive sites.

Carysfort Trench and Carysfort LighthouseIt is easily identified by the 100 feet high Carysfort lighthouse built in 1852.

The waters here, fed by the Gulf Stream, are rich in food and high in quality. As a result this is probably the healthiest reef in the whole system, with tremendous coral formations and spectacular fish including some predators. An excellent dive site to go scuba diving Florida Keys.

An interesting dive with some fabulous coral formations and plenty of colourful fish. We came across some barracuda hovering in the currents, beautiful to watch.
