94825 Overseas Hwy Unit 144

Key Largo is the northernmost and largest island in the Florida Keys, stretching about 30 miles along US-1 and serving as the gateway between mainland South Florida and the rest of the Keys chain. The island draws a steady mix of residents who work in tourism, marine trades, and hospitality, industries that form the backbone of the local economy. John Pennekamp Coral Reef State Park, the first undersea park in the United States, sits at the island's northern end and shapes much of the community's identity around diving, snorkeling, and boating. Florida International University's Aquarius Reef Base, an underwater ocean laboratory, adds a research dimension that reflects the island's deep connection to marine science.

Neighborhoods range from quiet residential pockets with single-family homes and canal-front properties to more commercial corridors along the Overseas Highway.
