Let’s be real for a second. If you look at a map, the distance from Orlando Florida to Key West Florida looks like a quick zip down the coastline. You see the peninsula, you see the dots of the Keys, and you figure you’ll be sipping a frozen Mojito on Duval Street by lunch.
You won't.
Unless you’re leaving at 3:00 AM, that drive is a beast. It’s roughly 390 miles, but miles in Florida are different than miles in, say, Kansas. In Florida, miles are measured in humidity, construction zones, and the unpredictable whims of the Florida Turnpike. Most people underestimate this trip because they just look at the raw numbers. They see "six and a half hours" on Google Maps and think that’s a hard rule. It’s actually more like a polite suggestion that rarely comes true.
Mapping Out the Actual Miles
If you take the most direct route—which basically means living on the Florida’s Turnpike and I-95—you’re looking at about 392 miles from the center of Orlando to the Southernmost Point marker.
But distance isn't just about the odometer.
The first 200 miles are a blur of cattle ranches and orange groves as you head south through Yeehaw Junction. Yeah, that’s a real place. It’s boring. It’s flat. It’s fast. But the moment you hit Homestead, the physics of the trip change. You transition from a high-speed expressway to the Overseas Highway (U.S. 1). This is where the distance from Orlando Florida to Key West Florida starts to feel a lot longer than it actually is.
The Overseas Highway is 113 miles of mostly two-lane road. If you get stuck behind a boat trailer doing 40 mph in a 55 mph zone, your arrival time starts slipping away like the tide. There are 42 bridges connecting the keys. They are beautiful, sure. The Seven Mile Bridge is an architectural marvel that makes you feel like you’re driving on water. But if there’s an accident on one of those bridges? You aren't moving. There is no "around." You just sit there and watch the pelicans.
Why Time Matters More Than Mileage
The GPS says 6 hours and 45 minutes. My personal record is nearly nine.
Traffic in Miami is a legendary nightmare. Even if you take the bypasses, you’re still flirting with the edge of one of the most congested corridors in the United States. To truly master the distance from Orlando Florida to Key West Florida, you have to account for the "Gateway to the Keys." Homestead is where the dream meets the reality of red lights and gas station stops.
- The Early Bird Strategy: Leaving Orlando at 4:00 AM sounds miserable, but it puts you through Miami before the morning rush and gets you to Key Largo for breakfast.
- The Mid-Day Mistake: If you leave Orlando at 10:00 AM, you hit Miami at 2:00 PM. That's the danger zone. You’ll be fighting commuters and tourists alike.
- The Saturday Slog: Avoid driving down on a Saturday morning if you can help it. Every boat owner in South Florida is headed the same way you are.
Honestly, the "distance" is mental. Once you pass "The Stretch"—that 18-mile span of U.S. 1 between Florida City and Key Largo—the air smells different. It’s saltier. You start seeing the turquoise water. The frustration of the Turnpike starts to melt, even if you’re still two hours away from Key West.

Breaking Down the Pit Stops
You shouldn't do this drive in one go. You’ll arrive in Key West grumpy and stiff. Since the distance from Orlando Florida to Key West Florida is basically an all-day affair, you need a strategy for stops.
Robert Is Here is a fruit stand in Homestead that everyone talks about for a reason. Their milkshakes are basically a religious experience. If you’ve been driving for four hours from Orlando, a guanabana or key lime milkshake is the fuel you need for the final leg.
Then there’s Islamorada. It’s roughly halfway between the start of the Keys and the end. Stop at Robbie’s Marina. You can feed massive tarpon from the dock. It’s touristy, sure, but it breaks up the monotony of the car. It reminds you that you're on vacation.
Flying vs. Driving: The Great Debate
Is it worth driving?
Flying from Orlando (MCO) to Key West (EYW) takes about an hour and ten minutes in the air. Silver Airways and American Eagle run these routes. It’s fast. It’s easy. You land right in the middle of the island.
But you miss the Seven Mile Bridge.
There is something inherently "Florida" about the drive. You see the transition from the theme park capital of the world to the "Conch Republic." You see the old bridges sitting abandoned next to the new ones, relics of Henry Flagler’s Over-Sea Railroad that was destroyed by the 1935 Labor Day Hurricane. You can't see that from 30,000 feet.
If you have a family, the drive is cheaper. Rental cars in Orlando are plentiful, but be warned: parking in Key West is a nightmare. Most hotels charge $40 or more per night just to let your car sit there. Once you arrive, you won't even use it. You'll rent a bike or a golf cart. So, you have to weigh the cost of gas and parking against the cost of a flight and Uber.
The Weather Factor
We have to talk about rain.

Central Florida and the Keys are prone to afternoon thunderstorms, especially from June through October. These aren't just sprinkles. These are "can't see the hood of your car" deluges. When one of these hits while you’re on the Turnpike, traffic slows to a crawl. People put their hazards on (which you shouldn't do in Florida, by the way, it's actually a point of contention with the highway patrol).
If a tropical system is anywhere in the Gulf or Atlantic, the distance from Orlando Florida to Key West Florida can become a logistical puzzle. The Keys are a mandatory evacuation zone for major hurricanes. If you see a cone of uncertainty heading toward Monroe County, do not start this drive.
Fuel and Logistics
Gas prices get higher the further south you go.
It’s a simple supply chain reality. Getting fuel out to a tiny island at the end of a chain involves more transport costs. Fill up in Florida City or Homestead before you hit the Overseas Highway. You’ll save 30 to 50 cents a gallon.
Also, SunPass.
If you are driving a rental or your own car, you need a SunPass. The Florida Turnpike is almost entirely electronic tolling now. If you don't have a transponder, they’ll snap a photo of your plate and mail you a bill (Toll-By-Plate), which usually comes with an administrative fee. Most rental companies will charge you a daily "convenience fee" for using their transponder. It’s often cheaper to buy a $5 "SunPass Mini" at a CVS or Publix in Orlando and load it with $20.
Hidden Costs of the Journey
People forget about the tolls. Driving the distance from Orlando Florida to Key West Florida via the Turnpike will run you about $15 to $25 in tolls depending on your exact exit and entry points.
Then there’s food. Roadside food in the Keys is great but pricey. You're paying for the view. A "cheap" lunch for two in Marathon or Islamorada can easily hit $50.
- The Time Cost: You lose a whole day of your vacation to the road.
- The Vehicle Cost: 400 miles each way is 800 miles round trip. If you’re renting, check for mileage caps (though most are unlimited now).
- The Stress: If you hate traffic, the Miami stretch will test your soul.
Navigating the Keys Once You Arrive
Once you finally finish that distance from Orlando Florida to Key West Florida, the road just... ends. US-1 terminates at a street sign at the corner of Whitehead and Fleming.

Key West is only about 4 miles long and 1 mile wide. You do not need a car. In fact, having a car is a liability. The streets are narrow, designed for 19th-century carriages and bikes.
If you drove down, park the car at your hotel and leave it there. Rent a bicycle. It’s the best way to see the architecture, the hidden gardens, and the roaming roosters. Yes, there are roosters everywhere. They are protected. Don't mess with them.
Is It Really "Only" 4 Hours?
I've seen some travel blogs claim you can do this drive in 4 or 5 hours.
They are lying.
To do Orlando to Key West in 5 hours, you would have to average nearly 80 mph without stopping a single time for gas, food, or a bathroom. With the speed limits in the Keys dropping to 35 mph or 45 mph through the residential areas (and the police in Big Pine Key are very strict because of the endangered Key Deer), a 5-hour trip is physically impossible without breaking a dozen laws.
Plan for seven. Be happy if it's six and a half. Expect eight.
Expert Tips for the Drive
- Check the Marathon Bridge Schedule: Sometimes the smaller drawbridges open for boat traffic. It’s rare on the main highway, but it happens.
- Download Offline Maps: Cell service is generally good, but there are pockets in the Everglades (the stretch between Homestead and Key Largo) where it can get spotty.
- The "Card Sound Road" Alternative: If you want a more scenic, slightly weirder entry into the Keys, take Card Sound Road instead of the main 18-mile stretch. It costs a small toll (cash or SunPass), and it takes you past Alabama Jack’s, a world-famous dive bar known for conch fritters.
- Watch for Key Deer: Between Marathon and Key West, specifically around Big Pine Key, watch your speed. Key Deer are tiny, cute, and very prone to jumping in front of cars. The fines for hitting one are massive, and the speed limits are strictly enforced at night.
The distance from Orlando Florida to Key West Florida is a rite of passage for Florida travelers. It's the transition from the artificial magic of Disney to the natural, weird, laid-back magic of the islands. It’s long, it’s hot, and sometimes it’s frustrating.
But when you finally park that car and walk over to Mallory Square to watch the sunset, you’ll realize the 390 miles were worth it.
Actionable Next Steps
- Check your SunPass: If you’re using your own car, ensure your account is active and has at least $30 to cover the round-trip tolls and any unexpected bypasses.
- Book a mid-way stop: If you aren't a marathon driver, look for a hotel in Islamorada for one night. It turns a grueling drive into two easy, scenic jaunts.
- Download your playlist/audiobooks: You will be in the car for a full workday. Make sure you have your entertainment downloaded offline, as the middle of the state can have dead zones.
- Verify parking at your destination: Call your Key West hotel and ask specifically about their "overnight parking fee." Knowing this cost upfront prevents "bill shock" at checkout.
- Time your departure: Aim to pull out of your Orlando driveway no later than 5:30 AM to beat the South Florida congestion.
