The Southernmost Point marker in Key West is the most popular selfie spot on the island.

A visit to Key West is not complete without a photo in front of the Southernmost Point marker. Located at the corner of South Street and Whitehead Street, this “buoy” designates Key West as the southernmost point in the continental United States. Interesting note: the true southernmost point on the island is a couple blocks away, but the marker was located here to better manage the photo-seeking crowds.
