French Reef is one of the most spectacular reef areas in the Florida Keys. There are dozens of ledges, tunnels, and caves to explore; most large enough to swim through. Bring your flash light and dive lights to check for fish inside the arches.

French Reef is known for its many caves and arches, easily accessible even to novice divers. At the south end is Hourglass Cave, named for its shape. Christmas Tree Cave is named for the large conical star coral mound that rises over the top located at the beginning of the coralformation.
