You've landed at Miami International Airport (MIA) with Key Largo on the itinerary — a dive resort, a waterfront rental, or the first stop on a longer Keys trip. The drive from Miami International Airport to Key Largo runs about 60 miles down a single highway, so how you cover it, and when you leave, matter more than the distance suggests. This guide lays out the exact distance and travel time, every transfer option including shuttles, the tolls and traffic to expect, and how to plan a return that doesn't put your flight at risk.
How Far Is Key Largo From Miami Airport?
The distance from Miami Airport to Key Largo is roughly 60 miles by road, and the drive takes about 1 hour 15 minutes in normal traffic. From MIA, the route follows the expressways to Florida's Turnpike Extension, which ends at US-1 in Florida City, then continues about 22 miles south on the Overseas Highway into Key Largo.
How far from Miami Airport to Key Largo you actually travel depends on where you're staying. Key Largo stretches roughly from Mile Marker 90 to 106, and locals use those green mile-marker signs as addresses, so a resort at the south end adds a few miles and minutes over one near the top. The Overseas Highway carries an All-American Road designation for its scenery, though the first section is more swamp and sky than ocean views.
Budget for a small toll. Florida's Turnpike Extension is all-electronic with no cash booths, so tolls are collected by SunPass, a compatible transponder, or Toll-by-Plate. The passenger-car charge is only a couple of dollars, but rental drivers should confirm how their company bills toll use before setting off.
Key Largo is the northernmost of the Florida Keys, which makes it the shortest Keys drive from Miami. If you're continuing all the way to Key West at Mile Marker 0, that's another two-plus hours south — the guide on Best Ways to Travel From Miami to Key West covers that longer route.
Getting From Miami International Airport to Key Largo: Transfer Options
With one highway linking Miami to the Keys, your choice comes down to a handful of options. Here's how they compare.
Private transfer or car service
A pre-booked private transfer takes you straight from baggage claim to your resort or rental door. You reserve a set vehicle and a fixed price in advance, a driver meets you with a sign, and you go door-to-door in about 75 minutes. It's a practical fit for divers and anglers with gear, families, groups, and anyone landing late, since the price is locked and the driver tracks your flight if it shifts.
Transpovia offers this kind of pre-booked, flight-tracked private transfer across its United States network, with fixed pricing, meet-and-greet pickup, and a range of vehicle sizes — useful when you're carrying dive bags or coolers to a specific lodge.
Shared shuttle
Shared-ride shuttle vans run between MIA and Key Largo, typically in the $100 to $130 range and around the same 75-minute drive time. You share the vehicle with other passengers, and some services use set drop points, so confirm whether the ride is door-to-door to your address. A shuttle from Miami Airport to Key Largo suits travelers who want a booked seat without paying private-car rates.
Rideshare (Uber and Lyft)
Uber and Lyft both operate at MIA's rideshare pickup area. A one-way ride to Key Largo is doable, though the fare over 60 miles is significant and can surge at busy times. The real problem comes later: the Keys have far fewer drivers, so booking a Miami airport to Key Largo shuttle or rideshare for the return trip can mean long waits or steep prices.
Rental car
MIA's Rental Car Center, reached by the automated MIA Mover train, houses all the major brands. Renting is popular for Keys trips because you'll want your own wheels to explore up and down US-1, from John Pennekamp Coral Reef State Park to the restaurants along the highway. Factor in the Turnpike toll and resort parking when you compare costs.
Bus and public transit
Greyhound runs a few buses daily from the MIA area toward Key Largo for a low fare, roughly $10 to $20, taking about 1 hour 20 minutes to the Key Largo stop. From there you'll need onward transport to your lodging. A cheaper county-transit connection exists through Florida City, but it involves transfers and long waits — impractical with luggage or dive equipment.
Taxi
Metered taxis wait at MIA, but over this distance they usually cost more than a flat-rate transfer arranged ahead. A taxi makes sense mainly for a short-notice single ride.

Tolls, Traffic, and the One Road In and Out
US-1 is the only main road into the Florida Keys, and that single point of access shapes every trip. The stretch between Florida City and Key Largo — known locally as the 18-Mile Stretch — is largely two lanes with limited passing zones. A single crash can back it up for an hour or more, and there's no quick detour; the alternate Card Sound Road helps only marginally.
Timing makes a real difference. Southbound Friday afternoons and northbound Sunday afternoons clog with Miami weekenders, and holiday periods run worse. Leaving early in the morning or later in the evening avoids the heaviest volume. On the toll side, remember the Turnpike Extension is cashless — SunPass or Toll-by-Plate only — so there's nothing to pay at a booth, but rental cars will bill the toll through their own program afterward.
Choosing the Right Option for Your Trip
The best choice depends on what you're carrying and who's along:
-
Divers and anglers with gear: A private transfer or rental car gives you room for equipment and a door-to-door drop at the dive lodge.
-
Families and groups: One private vehicle with car seats and luggage space usually beats splitting across rideshares.
-
Budget solo travelers and couples: A shared shuttle or Greyhound keeps costs down if you can flex your timing.
-
Late-night arrivals: A pre-booked transfer beats hunting for a scarce late rideshare.
-
Exploring beyond Key Largo: A rental car is the practical pick for hopping down the Overseas Highway.
This route rewards planning ahead, because on-demand rides thin out quickly once you leave Miami.
Planning Your Return Trip to Miami Airport
The return leg needs the biggest buffer of the whole trip. Work backward from your flight: allow about 75 minutes of driving, then add real padding for the 18-Mile Stretch and weekend northbound traffic, plus MIA's size and security lines — arriving two to three hours before departure is the standard guidance for a large international airport.
Because Keys rideshare supply is thin, book your return ride in advance; early-morning pickups are hard to get on demand. A pre-arranged, flight-tracked transfer removes the guesswork on a route where one road closure can cost hours, and a confirmed Transpovia pickup time suits early Keys departures when getting a car otherwise means gambling on availability.
Frequently Asked Questions
How far is Miami Airport from Key Largo?
The distance is about 60 miles by road, and the drive takes roughly 1 hour 15 minutes in normal traffic. Where you're staying in Key Largo — anywhere from Mile Marker 90 to 106 — shifts the exact figure slightly.
Is there a shuttle from Miami Airport to Key Largo?
Yes. Shared-ride shuttle vans run the route for around $100 to $130, and Greyhound buses serve it at a lower fare. Private transfers, rideshare, and rental cars are the other options; there's no train to the Keys.
How much is the toll from Miami Airport to Key Largo?
Florida's Turnpike Extension is cashless, charging only a couple of dollars for a passenger car via SunPass or Toll-by-Plate. Rental cars pass the toll along through their own toll programs, sometimes with a daily fee.
Do you need a car in Key Largo?
A car helps if you plan to explore up and down US-1, but if you're staying put at one resort, a transfer in and out can be simpler. Public transit in the Keys is limited, so pre-booking rides is wise either way.
Setting Off for the Keys
Match your ride to your gear and group: a flat-rate private transfer for door-to-door service to a dive resort or a late arrival, a shared shuttle or bus for budget trips, or a rental if you'll explore the islands. Most important, pad your return trip for the single road out. A pre-booked Transpovia transfer covers the door-to-door run when your timing is tight.
