MARATHON, Florida Keys -- About two miles west of Marathon, nestled beneath what is now called the Old Seven Mile Bridge, lies Pigeon Key. The five-acre island once served as a base camp for workers during construction of the original Seven Mile Bridge, the centerpiece of Henry Flagler’s Overseas Railway. A museum on the island chronicles the construction of the railorad. Accessible by ferry, Pigeon Key also welcomes many visitors who walk or bike to it along a scenic portion of the Old Seven Mile Bridge, closed to vehicular traffic since 2007.

The 120-mile Florida Keys island chain is home to the continental United States' only living-coral barrier reef. This teeming backbone of marine life runs the length of the Keys about five miles offshore and offers Florida Keys scuba diving vacation memories that last a lifetime.

Our coral formations are famous for their abundance of fish, from impressive schools of blue-striped grunts to toothy green moray eels. The U.S. government established the Florida Keys National Marine Sanctuary to protect our marine habitat.

Preserving the reef is a top priority for a good reason. There is no more versatile marine destination in the world. We have coral-encrusted ship wrecks and intricate natural coral formations. We have shallow reefs for snorkelers, and a range of deeper reefs for experienced divers.

Most dive sites are equipped with convenient mooring buoys to save the reef from anchors and make it easy for boaters to tie off. Most sites are a short boat ride from our islands, where dozens of highly professional dive operators are ready to cater to you.

Once you visit the Keys, you'll see why some of the some of the most renowned dive photographers and writers in the world make this their home base.
