For the bus from Miami to Key West, the simplest choice is the direct Greyhound or FlixBus coach. The ride follows US-1 through the Florida Keys, costs far less than a shuttle or flight, and saves you from driving into Key West, where parking can be tight and pricey.
The main catch is timing. Current direct buses leave in the morning, not all day, so this route works well for travelers who can start early and do not need a late-afternoon departure.
Miami To Key West By Bus: Every Route Compared
Miami to Key West by bus is cheapest and easiest when you take the direct coach. The public-bus combination can cost less, but the transfer timing makes it a poor fit for most visitors with luggage.
After you compare the route options below, use this to check current bus and transfer choices for your dates:
How Long Does The Miami To Key West Bus Take?
The Miami to Key West bus takes as little as 4 hours 30 minutes on the fastest listed direct service. The route covers about 159 miles and ends at Key West Airport, not Old Town.
Current Greyhound and FlixBus listings show 3 daily rides, a first departure around 5:00 a.m., and a last departure around 11:00 a.m. Fares move with date and demand, but the current fare floor shown for the direct route is from $25.48.
Miami boarding points can include Miami Intermodal Center near Miami International Airport, Downtown Miami at Bayside Marketplace, Miami Golden Glades, and Miami Beach. Key West arrivals use Key West Airport at 3439 S Roosevelt Blvd, so plan one more local ride if your hotel is near Duval Street, Mallory Square, or the Historic Seaport.
Which Miami Stop Should You Choose?
The right Miami bus stop depends on where you sleep the night before. Miami Intermodal Center is the cleanest choice for airport travelers, while Downtown Miami and Miami Beach stops can save a cross-city ride if you are already there.
- Miami Intermodal Center: choose this for Miami International Airport, Metrorail, Tri-Rail, or an airport hotel.
- Downtown Miami: choose this for Brickell, Downtown hotels, Bayside Marketplace, or a cruise-port-area stay.
- Miami Beach: choose this only if you are already on the beach side, since crossing to the mainland can add traffic time.
- Golden Glades: choose this for North Miami, Aventura, or travelers coming from Broward County.
Boarding detail: your ticket address matters more than the city name. Check the exact stop printed on the ticket before you leave your hotel.
Bus, Shuttle, Car, Or Flight: Route Options
The direct bus wins on price, while a rental car wins only if the drive itself is part of the trip. A flight is faster in the air, but airport time can erase much of the advantage.
| Mode | Typical Time | Rough Cost |
|---|---|---|
| Direct Greyhound or FlixBus coach | From 4h30; about 159 miles | From $25.48 on current listings |
| Public bus combo via Florida City and Marathon | Often 6-8h with transfers | Low local fares, usually under direct shuttle cost |
| Key West day-trip bus tour | Full-day outing, often 12-13h round trip | Often mid-range, depending on add-ons |
| Rental car from Miami | About 3.5-5h, longer with stops | Rental, gas, tolls, and Key West parking |
| Private airport shuttle van | About 4-5h door to door | Commonly around $165-$175 per person |
| Private car or ride app | About 3.5-5h | Often several hundred dollars |
| Flight from Miami to Key West | About 1h in air plus airport time | Usually higher than the bus |

What To Know Before You Buy The Ticket
The Miami to Key West coach is easy if you treat it like an intercity bus, not a hotel shuttle. Bring food, arrive early, and plan the Key West arrival transfer before you board.
- Buy morning tickets early. The cheapest seats can sell out first, and later departures are limited.
- Pack for one checked bag and one carry-on. Standard allowance varies by operator and fare type, so read your ticket terms before adding a second bag.
- Do not plan a tight dinner reservation. US-1 traffic, bridge work, storms, and holiday traffic can slow the approach into Key West.
- Use a mobile ticket. Current operator pages say printed tickets are not needed, but your phone should be charged before boarding.
- Choose Old Town lodging if you want to walk later. A hotel near Duval Street, the Historic Seaport, or Mallory Square reduces local transport after arrival.
Should You Take The Commuter Bus Instead?
The commuter-bus route is only worth it if your top goal is the lowest possible fare and you can absorb missed transfers. Most visitors should take the direct coach because it avoids changing buses in Florida City and Marathon.
The local route uses Miami-Dade Transit Route 301 between Florida City and Marathon, then the Lower Keys Shuttle between Marathon and Key West. That can work for slow travel, workers, or travelers already staying near Florida City, but it is not the smooth choice after a flight into Miami.
The transfer risk matters because the Keys are linear. A missed connection does not leave you with many backup routes, and rideshare coverage gets thinner as you move down the islands.
Where To Stay After The Bus Arrives
Key West Airport is east of the main visitor areas, so the easiest post-bus plan is to sleep in Old Town or near the Historic Seaport. New Town can be cheaper, but Old Town saves taxi rides once you arrive.
Travelers focused on nightlife should look near Duval Street. Travelers who want quieter evenings should look around the Historic Seaport, Truman Annex, or the south end near the beaches.
After you know your arrival stop, compare Key West hotels on a map so you can see the distance from the airport and Old Town before choosing a room:
When A Car Makes More Sense
A car makes more sense when you want to stop in Key Largo, Islamorada, Marathon, Bahia Honda State Park, or other Florida Keys spots on the way. The bus is better when Key West itself is the destination.
Driving also helps families carrying beach gear or travelers splitting costs across three or four people. Still, Key West is compact, and parking near Old Town can turn a cheap rental into a more expensive plan.
- Drive if the Overseas Highway stops are part of the trip.
- Take the bus if you want the cheapest direct point-to-point ride.
- Fly only if schedule matters more than cost.
- Use a private shuttle if door-to-door airport service matters more than price.
The Verdict For Speed, Budget, And Comfort
The direct coach is the strongest choice for budget travelers, solo travelers, and anyone who does not want to park in Key West. A rental car is the better fit for a road-trip day with planned stops, not for a simple transfer.
Use this split to decide:
- Cheapest direct option: Greyhound or FlixBus coach from Miami to Key West.
- Fastest door-to-door option without driving: private shuttle or private transfer.
- Most flexible option: rental car from Miami, especially with Florida Keys stops.
- Least stressful arrival: direct coach plus an Old Town hotel.
If you are ready to compare same-day schedules, start with the direct coach and only switch to a shuttle or car if the departure times do not fit:
