Things to do nearSouthernmost Point of Mainland US

The Southernmost Point of Mainland US has been a defining landmark of Key West since the large concrete buoy-shaped monument was installed in 1983, replacing a simple sign that visitors kept stealing as a souvenir. Positioned at the corner of South Street and Whitehead Street, the marker sits just steps from the Atlantic shoreline and draws visitors from around the world who come to stand at the continental edge of the United States. The painted concrete structure is deceptively large up close, and the inscription noting the 90-mile distance to Cuba gives the spot a genuine sense of geographic drama.

Key West itself is steeped in maritime and literary history, and wandering the surrounding Old Town neighborhood reveals wooden Conch-style homes, century-old banyan trees, and streets that have barely changed in decades. Ernest Hemingway lived and wrote nearby, and the area around the Southernmost Point of Mainland US sits within easy walking distance of his preserved home. The broader waterfront offers opportunities for snorkeling excursions, sunset sailing tours, and glass-bottom boat trips departing from the historic seaport.

The local food scene leans heavily on fresh seafood, with conch fritters, grilled mahi-mahi, and stone crab claws appearing on menus throughout Old Town. The atmosphere at the marker itself is lively and communal, a place where strangers take photos for one another and share a quiet moment of collective geography. Few spots in the country carry quite the same blend of natural beauty and symbolic weight, making it a genuinely meaningful stop on any Florida Keys itinerary.
