Overview and Quick Answer
The drive from Fort Myers to Key West is a classic Florida itinerary that follows the scenic Overseas Highway, spanning approximately 130 to 140 miles and taking about 3.5 to 5 hours of actual travel time, not including stops. This route connects the Gulf Coast to the Florida Keys via a chain of islands, delivering tropical scenery, wildlife refuges, and ocean views. It is an evergreen, practical travel question with broad search interest from road-trippers, winter visitors, and vacation planners seeking a reliable, well-planned journey.
Route Overview and the Overseas Highway
The most direct and popular route is via U.S. Route 1 (US 1) south to Key Largo, then the Overseas Highway (Florida Route A1A) through the Keys. From Fort Myers, you merge onto US 41 South, which becomes US 1 South as you approach Naples. After passing through Naples, you continue onto the Ten Thousand Islands area and then cross to Key Largo, where the iconic Overseas Highway begins. The highway traverses a string of keys, including Key Largo, Islamorada, and the Upper Keys, before ending in Key West. This road is renowned for its bridges, turquoise water views, and access points for rest, photos, and refueling.
Key Segments and Landmarks
- Fort Myers to Naples: Urban and suburban segments, with access to shopping and services.
- Naples to Key Largo: Transition to coastal scenery, with options to detour to Everglades National Park.
- Key Largo to Key West: The Overseas Highway, featuring bridges, lookout points, and historic sites.
Distance and Drive Time Estimates
The distance from Fort Myers to Key West typically ranges from 130 to 140 miles, depending on your exact starting point in Fort Myers and whether you take the most efficient route. Driving time usually falls between 3.5 and 5 hours of active travel, influenced by traffic, weather, and the frequency of rest stops. These ranges reflect typical conditions; during peak tourist seasons or after rain, congestion and slower truck traffic can extend both distance time and total trip duration.
Stops, Services, and Key Locations
Plan for at least one fuel stop, as well as breaks for food and rest, especially on the longer segments between Keys. Key Largo offers marinas and visitor centers; Islamorada provides dining and lodging options; and the Lower Keys include notable attractions such as the Seven Mile Bridge and Key West Historic Seaport. In Key West, allow time to explore Duval Street, the Southernmost Point marker, and harbor areas. Factor in additional time if you intend to visit state parks, beaches, or cultural sites along the way.
Seasonal Considerations and Weather Impact
Winter months bring increased tourist traffic, which can slow traffic on the Overseas Highway, particularly on weekends and holidays. Summer can introduce afternoon thunderstorms and occasional tropical weather, which may affect visibility and road conditions. Fog and reduced visibility can occur on bridges, so drive with headlights on and maintain safe following distances. Check road and weather forecasts before departure, and be prepared for temporary delays due to construction or emergency incidents.
Practical Planning and Checklist
Successful travel from Fort Myers to Key West hinges on preparation, timing, and realistic expectations for driving segments. Consider fuel range, restroom availability, and lodging preferences on longer trips. Early departures can help avoid midday heat and peak traffic. Pack essentials such as water, snacks, navigation tools, and a charged phone, and review alternate routes and contingency plans for severe weather.

Carry a basic emergency kit, keep a physical map as a backup, and monitor local traffic and weather updates.

If you are unfamiliar with the keys, allow extra time to learn local layouts and one-way streets, particularly in Key West.
