At the southernmost point of the continental United States, the iconic U.S. Highway 1 finds its conclusion at Mile Marker 0. The alluring, blue-green water found here at the tip of Key West is as vibrant and crystal clear as it was when Hemingway first set sail in this region of the Gulf of Mexico. In the nearly hundred years since, countless others have found inspiration in these turquoise waters and in the bustling coral reefs that lie just below the surface. Listen to the calming sounds of this aquatic paradise and let the salty tang of sea air fill your lungs, each breath replenished with the ebb and flow of gently passing waves. 24.54656, -81.79749
