The Florida Keys Reef is the only living coral reef in the continental United States and the third largest barrier reef system in the world, after the Great Barrier Reef and the Belize Barrier Reef. It runs along the seaward side of the Florida Keys and is typically about 3-4 miles from the islands. Sombrero Reef lies just 4 miles from Boot Key Harbor. There is a cool lighthouse (one of six along the Florida Keys Reef) sitting on top of the reef and lots of mooring buoys surrounding it. We can sail right up to the reef and hook onto a buoy for an afternoon of snorkeling right off the boat.
An interesting tidbit is that the government has decided these lighthouses are no longer necessary and will be donating them for free to interested non-profits. If there are no takers, they will sell them at auction to the general public. Anyone want to own a lighthouse?
