Key West and County Government
Key West is the county seat and the principal urban and cultural center of the Florida Keys. Old Town, the harbor, naval facilities, an airport, and visitor services are concentrated there.
Detailed streets, docks, and harbor facilities require local or nautical maps.
Marathon and the Middle Keys
Marathon is the main Middle Keys city, with marinas, an airport, healthcare, commerce, and access to the Seven Mile Bridge. Key Colony Beach is a nearby incorporated city.
Bridge, road, and storm-recovery conditions should be checked before travel.
Islamorada and the Upper Keys
Islamorada is a village spread across several islands and is associated with sport fishing, diving, and marine tourism. Key Largo is a major unincorporated gateway to the upper Keys and reef region.
Marine-protection and fishing rules vary by location, so current agency guidance is required.
Everglades and Dry Tortugas
Most of the county’s mainland area is wetlands and mangrove landscape within or near Everglades National Park. Dry Tortugas National Park contains remote islands and Fort Jefferson west of Key West.
Access is limited and depends on park, ferry, boat, or seaplane conditions.
