The real choice in how to get to Key West from Miami is whether you want control, low cost, or the shortest airport-to-airport hop. Most travelers should drive or take the bus: the road distance is about 159 miles, the fastest scheduled bus takes about 4 hours 30 minutes, and the drive usually needs 3.5 to 4.5 hours before stops and traffic.
Flying from Miami International Airport (MIA) to Key West International Airport (EYW) can take about an hour in the air, but security, airport transfers, boarding time, and baggage can shrink the advantage. A direct ferry from Miami to Key West is not a regular option; the Key West Express leaves from Fort Myers Beach or Marco Island on Florida’s Gulf Coast, which makes it a detour for anyone starting in Miami.

Miami To Key West Transport: Every Route Compared
Miami to Key West transport comes down to seven realistic choices, but only three make sense for most trips: drive, bus, or fly. The bus is the budget pick, driving is the flexible pick, and flying is the speed pick if your schedule lines up cleanly.
Use this table as the planning baseline, then adjust for weekend traffic, hotel check-in time, baggage, and whether you want to stop in Key Largo, Islamorada, Marathon, or Bahia Honda State Park along the way.
| Mode | Typical Time | Cost Logic |
|---|---|---|
| Drive Your Own Car | About 3.5–4.5 hours without long stops | Fuel, possible tolls, and Key West parking |
| Rental Car | About 3.5–4.5 hours, plus pickup time | Daily rental rate, fuel, insurance choices, and possible one-way fee |
| Greyhound Or FlixBus | Fastest listed trips about 4 hours 30 minutes | Fares currently start around $25.48 when booked early |
| Shared Shuttle | Usually about 4.5–5.5 hours | Higher than bus, lower than a private transfer |
| Private Transfer | About 3.5–4.5 hours, traffic dependent | Highest road cost, useful for groups or late arrivals |
| Nonstop Flight MIA To EYW | About 55–75 minutes in the air | Fare varies sharply; add airport time at both ends |
| Ferry Via Fort Myers Or Marco Island | 2.5+ hours driving from Miami, then about 3.5 hours by ferry | Usually poor for Miami starters unless the Gulf Coast is already in your plan |
How Long Does The Miami To Key West Trip Take?
The Miami to Key West trip takes about 4 hours by road on a clean day, but traffic can add real time on weekends, holidays, and after accidents on U.S. 1. The safest planning window is half a day if you want to arrive calm, eat lunch, or stop for photos.
The Florida Keys route is simple on a map but narrow in practice. Much of the drive follows U.S. 1 through island towns, bridges, lower speed zones, and limited passing areas. The official Florida Keys tourism site describes the Overseas Highway as 113 miles from Key Largo to Key West with 42 bridges, and Key West sits about 159 miles from Miami on the mile-marker system, per the Florida Keys getting-here page.
For a same-day transfer, leave Miami early. For a road trip, split the route into stops: Key Largo for John Pennekamp Coral Reef State Park, Islamorada for lunch, Marathon for the Seven Mile Bridge area, and Bahia Honda State Park for a beach break before the final push into Key West.
Driving From Miami To Key West
Driving is the right choice if you want stops, luggage freedom, and control over your arrival time. The road is easy to follow, but the route is slower than the mileage suggests because U.S. 1 is the only road in and out of the Keys.
Expect the drive to feel relaxed on weekday mornings and slower on Friday afternoons, holiday weekends, and during winter high season. Start with a full tank before the Keys, do not plan tight dinner reservations on arrival night, and avoid nighttime driving if you are tired after a flight into Miami.
- Choose driving if: you want the Seven Mile Bridge, roadside seafood, state parks, and flexible photo stops.
- Skip driving if: your Key West hotel charges steep parking fees, your group wants to drink in Old Town, or you only have one night.
- Watch the return: Sunday traffic back toward Miami can drag, so leave Key West early or stay one more night.
If you need wheels for the route, compare pickup points in Miami rather than assuming the airport counter is cheapest. Downtown, Miami Beach, and airport rental desks can price differently, and one-way drop-off into Key West can change the total.
Taking The Bus Or Shuttle
The bus is the cheapest practical way to reach Key West from Miami, especially for solo travelers. Greyhound and FlixBus list the route at about 159 miles, with the fastest trips around 4 hours 30 minutes and several daily departures on many dates.
The trade is flexibility. Bus travelers give up roadside stops and need to match the departure point, luggage rules, and arrival point to their hotel plans. Miami Beach departures can be handy for visitors staying on Collins Avenue, while Key West Airport arrivals work well if you plan to taxi or rideshare into Old Town.
Shared shuttles cost more than the bus but can be easier from Miami International Airport or a Miami hotel. A private transfer only makes financial sense for families, groups with luggage, late-night arrivals, or travelers who want door-to-door service with no schedule stress.
Flying From Miami To Key West
Flying is the fastest air time, not always the fastest whole trip. American Airlines operates nonstop service between Miami International Airport and Key West International Airport on many dates, with scheduled flight times often around one hour.
Flying works best when you are connecting through Miami by air and can keep the transfer inside the airport system. Flying works less well when you are already in Miami Beach or downtown, because the taxi to MIA, security, boarding, baggage claim, and the taxi from EYW into Old Town can eat the time saved in the sky.
Flights also make sense for travelers with mobility limits who do not want a long road transfer, or for tight business-style schedules where time matters more than cost. For a leisure trip of two nights or more, the drive or bus is usually the better value.
Where To Stay After You Arrive In Key West
Key West is compact, but the right hotel area changes how much you walk, taxi, or park. Old Town and the Historic Seaport suit first-time visitors without a car, while New Town and Stock Island can price lower if you are driving.
Look carefully at parking before booking. A cheaper room can lose its edge if nightly parking is high or if you end up taking rideshares across the island each day. For a car-free trip, staying near Duval Street, Mallory Square, or the Historic Seaport keeps the arrival day easy.
Use the map to compare Key West hotel locations against your arrival point, parking needs, and Old Town plans:
Miami To Key West Route Picks By Traveler Type
The right Miami to Key West route depends on your time, budget, luggage, and tolerance for slow traffic. This table gives the clean pick for each common traveler, without forcing one answer onto every trip.
| Traveler Type | Pick | Why It Fits |
|---|---|---|
| Solo Budget Traveler | Bus | Lowest current starting fare and no parking cost in Key West |
| Couple On A First Keys Trip | Drive | Stops in Key Largo, Islamorada, Marathon, and Bahia Honda make the route part of the trip |
| Family With Luggage | Rental Car Or Private Transfer | Less handling of bags and easier door-to-door timing |
| Short Weekend Visitor | Fly Or Early Bus | Saves daylight if fares and departure times line up |
| Road-Trip Planner | Drive Over Two Days | Gives enough time for the Overseas Highway without rushing every stop |
| Car-Free Key West Stay | Bus, Shuttle, Or Flight | Old Town is walkable, and parking can be expensive |
| Gulf Coast Add-On | Key West Express Ferry | Works from Fort Myers Beach or Marco Island, not as a direct Miami route |
Best Way For Speed, Budget, And Comfort
The best overall way from Miami to Key West is to drive if you want the Florida Keys experience, take the bus if price matters most, and fly only when the schedule beats the full road transfer. A direct Miami ferry is not the answer for this route.
- Best for most first-timers: Drive from Miami in the morning, stop twice, and arrive in Key West before sunset.
- Best for lowest cost: Take Greyhound or FlixBus, then taxi or rideshare from the Key West stop to your hotel.
- Best for no-driving comfort: Use a shared shuttle from Miami International Airport or a Miami hotel.
- Best for tight schedules: Fly MIA to EYW only if the fare, departure time, and airport transfers all work cleanly.
- Best to avoid: Treating the Fort Myers or Marco Island ferry as a Miami shortcut; it is a Gulf Coast option, not a direct Miami route.
For a smooth plan, book the transport first, then match your Key West hotel to the way you arrive. Drivers should care about parking; bus and shuttle travelers should care about walking distance; flyers should care about the short but paid ride from Key West International Airport into Old Town.
