Key Largo is the entrance to the Florida Keys. It’s only an hour ride to South Florida’s two major airports, but it feels like a world away. Key Largo is the largest and northernmost island in the Florida Keys. It is sandwiched between the watery wilderness of the Everglades National Park to the west and the fish-covered coral formations of North America’s only living barrier reef to the east. Locals hail it as the diving capital of the world, but the area is equally noted for its sportfishing. Key Largo is comprised of primarily residential properties, with many commercial properties scattered along U.S. 1 and marinas along the shore line.
