Miami to Key West: The Complete Drive & Private Car Guide
The drive from Miami to Key West is one of the great American road trips — 160 miles down US-1 and the Overseas Highway, across 42 bridges, with the Atlantic on one side and the Gulf on the other. Here is everything you need to plan it: how long it takes, the best stops, when to go, and whether to drive, fly, or let a chauffeur do the driving.
The short version: Miami to Key West is ~160 miles and 3.5–4 hours on US-1. You can drive it, fly MIA→EYW, take a shuttle, or book a private chauffeur door-to-door from about $750 one-way. Key West is walkable and parking is scarce, so many travelers skip the rental and arrive relaxed by private car. Call (786) 460-4536.
How long is the drive from Miami to Key West?
The drive is about 160 miles and takes 3.5 to 4 hours in good conditions. From Miami you take US-1 south through Florida City and across the 18-mile stretch into the Keys, then follow the Overseas Highway down the island chain. There is only one road in and out, so the actual time depends heavily on the day and season — a single fender-bender on a two-lane section can add an hour, and winter-season weekends bring real congestion.
The Overseas Highway runs 113 miles across 42 bridges, the most famous being the Seven Mile Bridge near Marathon. Mile markers (MM) count down as you go: Key Largo begins around MM 106, Marathon sits near MM 50, and Key West is MM 0. Locals navigate entirely by mile marker, and so will your chauffeur.
The four ways to get from Miami to Key West
There is no single "best" way — it depends on your party, your budget, and how much you value comfort. Here is the honest comparison.
| Option | Time | Best for | Trade-off |
|---|---|---|---|
| Drive / rental car | 3.5–4 hr | Flexible explorers | Scarce, costly Key West parking |
| Shuttle / bus | 4.5–5 hr | Solo budget travel | Fixed schedule & stops |
| Fly MIA → EYW | ~1 hr + airports | Time-sensitive trips | Small airport, higher fares, no scenery |
| Private chauffeur | 3.5–4 hr | Couples, families, groups | Premium flat rate |
Flying saves time on paper, but once you add airport security, the small Key West airport, and ground transport on both ends, the door-to-door difference shrinks. Driving yourself is the classic choice — just remember that Key West is a compact island where a car becomes a liability the moment you arrive. That is why a growing number of visitors book a private car service in Miami and let someone else handle the road.
The best stops along the Overseas Highway
Half the reason to drive rather than fly is the journey itself. These are the stops worth building into your day:
- Key Largo (MM 106): John Pennekamp Coral Reef State Park, the first underwater park in the United States — glass-bottom boats and some of the best snorkeling in the country.
- Islamorada (MM 90–73): the self-styled sport-fishing capital of the world. Stop at Robbie's of Islamorada to hand-feed the giant tarpon, or grab lunch with a water view.
- Marathon (MM 50): the Turtle Hospital, Sombrero Beach, and the western end of the Seven Mile Bridge. A natural halfway rest point.
- Bahia Honda State Park (MM 37): just past the Seven Mile Bridge, regularly ranked among Florida's most beautiful beaches, with views back toward the old railroad bridge.
- Big Pine Key (MM 30): home of the tiny, protected Key deer, and the famously off-grid No Name Pub.
By the time you reach Key West (MM 0) — Duval Street, Mallory Square at sunset, the Hemingway Home, and the Southernmost Point buoy — you have already seen the best of the drive.
Chauffeur tip: With a private car, the stops are yours to choose. Many Detailed Drivers clients ask for a lunch stop in Islamorada and a 15-minute photo stop at the Seven Mile Bridge or Bahia Honda — no negotiating with a tour schedule, and no one in your party has to skip the view to keep their eyes on the road.
When is the best time to make the drive?
Leave early. A morning departure beats the worst traffic and gets you to Key West in time for lunch and an afternoon on the water. Avoid southbound US-1 on Friday afternoons and northbound on Sunday afternoons, when weekend traffic stacks up at the 18-mile stretch in the upper Keys.
Winter season — December through April — is the busiest and the most pleasant, with low humidity and packed events. Summer is quieter and hotter, and hurricane season runs June through November, when it pays to watch the forecast. Because there is a single road in and out, a professional chauffeur who monitors conditions and times the departure is worth more here than on almost any other Florida route.
How much does a private car to Key West cost?
A private chauffeured transfer from Miami to Key West with Detailed Drivers starts at about $750 one-way for an Executive Sedan and $950 for a First Class SUV, as a flat rate that never surges. The Mercedes-Benz S-Class is available for VIP arrivals, and the 10–14 passenger Mercedes-Benz Sprinter Van carries a whole group with luggage for a single price. The rate covers the entire vehicle, door-to-door, with curbside meet-and-greet at Miami International Airport, flight tracking, and any stops you want along the way.
Compared with a rental — once you factor in the rental rate, gas, tolls, and Key West parking at $25–$45 a day — the gap narrows quickly, and the chauffeur removes the two things travelers like least: the 4-hour drive and the parking.
Should you skip the rental entirely?
For most Key West trips, yes. The island is roughly four miles by two, and the entire historic district is walkable. Visitors get around on foot, by bicycle, or by scooter, and the major hotels are minutes apart. A rental car spends your trip sitting in a paid lot. Arriving by private chauffeur — and booking a car back to Miami or the airport when you leave — means you never touch a steering wheel or a parking meter.
Detailed Drivers also handles the rest of South Florida from the same fleet, so a Key West trip pairs naturally with a Miami car service day or another Gulf-coast route such as Miami to Naples.
Starting from Fort Lauderdale instead of Miami?
Plenty of Key West travelers start in Fort Lauderdale — flying into FLL for the fares, finishing a cruise at Port Everglades, or staying on Las Olas. From Fort Lauderdale, Key West is about 200 miles and 4 to 4.5 hours: south on Florida's Turnpike or I-95 to join US-1 and the Overseas Highway through the Keys. Detailed Drivers runs the same door-to-door private chauffeur service from any Fort Lauderdale hotel, Port Everglades, or curbside at Fort Lauderdale car service and FLL — flat-rate from about $850 one-way for an Executive Sedan and $1,050 for a First Class SUV, no surge, with the same Islamorada and Bahia Honda stops on request. It is the easy way to turn an FLL arrival or a cruise disembarkation into a relaxed run down to the island.

A private chauffeur can build any of these into the drive.
When is the best time to drive from Miami to Key West?
Leave Miami early in the morning to beat traffic and arrive in Key West for lunch. Avoid southbound US-1 on Friday afternoons and northbound on Sunday afternoons, when weekend traffic backs up at the 18-mile stretch through the upper Keys. Winter season (December through April) is the busiest and most beautiful time; summer is quieter but hotter, and hurricane season runs June through November. There is only one road in and out, so a single accident can cause long delays — a professional chauffeur monitors conditions and times the drive.
Is it worth hiring a chauffeur instead of driving to Key West?
For many travelers, yes. Key West is a compact, walkable island where a car is more of a burden than a benefit — parking is limited and expensive, and most visitors get around on foot, by bike, or by scooter once they arrive. A private chauffeur means you arrive relaxed after the 4-hour drive, with no rental to manage or park, the freedom to stop for lunch in Islamorada or photos at the Seven Mile Bridge, and a guaranteed ride that doesn't surge. For groups, one Sprinter Van replaces three or four cars.
Can I get a private car from MIA airport directly to Key West?
Yes — Miami International Airport (MIA) to Key West is a common Detailed Drivers booking. The chauffeur meets you curbside at your MIA terminal with a printed name sign, tracks your flight, loads your luggage, and drives US-1 south to your Key West hotel or vacation rental. Many travelers fly into Miami for the connections and fares, then take a private car the rest of the way rather than connecting to the small Key West airport. Fort Lauderdale (FLL) pickups are also available.
How many bridges are on the drive to Key West?
The Overseas Highway crosses 42 bridges between the mainland and Key West. The most famous is the Seven Mile Bridge near Marathon, one of the longest bridges in the world when it was built and a landmark of the drive. The bridges connect the chain of islands that make up the Florida Keys, with open water and the Atlantic and Gulf on either side for much of the route.
Can I get a private car from Fort Lauderdale or FLL to Key West?
Yes — Fort Lauderdale to Key West is about 200 miles and 4 to 4.5 hours. The route runs south on Florida's Turnpike or I-95 to join US-1 and the Overseas Highway through the Keys. Detailed Drivers picks you up at any Fort Lauderdale hotel, at Port Everglades, or curbside at Fort Lauderdale-Hollywood International Airport (FLL) with flight tracking, then drives door-to-door to your Key West hotel — flat-rate from about $850 one-way for an Executive Sedan and $1,050 for a First Class SUV, no surge, with optional stops in Islamorada or at Bahia Honda. Many travelers fly into FLL for the fares and take a private car the rest of the way. Call (888) 420-0177.
