Alligator Reef Light stands in the turquoise waters off Islamorada, Florida, its iconic iron skeleton tower rising above the shallow reef since 1873. Built to warn mariners away from the dangerous Alligator Reef — named after the USS Alligator, a Navy schooner that ran aground here in 1822 — the lighthouse served for over a century before being deactivated. Its striking open-framework design makes it one of the most photogenic reef lights in the Florida Keys. The tower is not open to public access or climbing. Early morning and sunset offer the best photography conditions, with calm waters enhancing reflections. Nearby, visitors can explore Robbie’s Marina, snorkel at local reefs, or kayak through Indian Key Historic State Park.
