Florida is huge. People forget that. You see the peninsula on a map and think, "Oh, it's just one state, how long could it possibly take?" Then you actually get behind the wheel in Jacksonville and realize you've got a massive trek ahead of you before you even smell the saltwater of South Beach. Honestly, the distance between Jacksonville and Miami is one of those things that catches tourists—and even some new residents—completely off guard.
So, how far is Jacksonville from Miami? If you're looking for the quick, "as the crow flies" answer, it’s roughly 317 miles. But you aren't a crow. You're likely sitting in a car, probably on I-95, staring at the taillights of a semi-truck near Daytona.
In reality, you're looking at about 340 to 350 miles of driving. That translates to roughly 5 to 6 hours if the traffic gods are smiling on you. They usually aren't.
The Interstate 95 Grind
Most people just hop on I-95 South and stay there until the buildings get taller and the drivers get more aggressive. It’s the most direct path. It’s also a psychological gauntlet.
Starting in Jacksonville, you’ve got a bit of a "warm-up" period. The drive down to St. Augustine is usually breezy, but once you hit the stretch between Palm Coast and Daytona Beach, things start to feel long. You’re looking at hundreds of miles of pine trees and billboards for personal injury lawyers. It’s rhythmic. It’s boring. It’s Florida.
The mileage doesn't tell the whole story. Traffic is the real protagonist here. If you leave Jacksonville at 8:00 AM on a Tuesday, you’re going to hit the lunch rush in the Space Coast and the absolute nightmare of West Palm Beach and Fort Lauderdale rush hour by the time you’re closing in on Miami. I’ve seen that "5-hour drive" turn into an 8-hour ordeal because of a single fender-bender in Boca Raton.

Why the Florida Turnpike is Your Best Friend
A lot of GPS apps will try to shave off a few minutes by suggesting the Florida Turnpike. Take it.
You usually jump on the Turnpike around Fort Pierce. Yes, you have to pay tolls. No, it isn't "pretty." But the Turnpike is generally better maintained and has fewer "local" drivers hopping on and off every two miles like they do on I-95. It feels faster even if the odometer says it’s about the same distance. Plus, the service plazas (like the one in Fort Drum) are weirdly nostalgic and a great place to grab a Cuban coffee before the final push into Miami-Dade County.
Is Flying Actually Faster?
Sometimes.
When you factor in the "airport math," it's a toss-up. A flight from Jacksonville International (JAX) to Miami International (MIA) or Fort Lauderdale-Hollywood (FLL) is only about an hour and ten minutes in the air.
- Drive to JAX: 30-45 mins.
- Security and waiting: 90 mins.
- Flight time: 70 mins.
- Deplaning and Uber to your hotel: 60 mins.
You've spent four hours and a lot more money. If you have a family of four, you're better off driving. If you're a solo business traveler who needs to work on the plane, flying wins. American Airlines usually runs this route frequently, but don't expect "budget" prices unless you book way out.

The Scenic Route: A1A
If you aren't in a rush, don't use the highway. Seriously.
If you take A1A, you’re basically hugging the Atlantic Ocean the entire way. It is stunning. It will also take you two days if you actually want to enjoy it. You’ll pass through places like Flagler Beach, where the sand is orange-cinnamon colored, and Vero Beach, which feels like Florida did forty years ago.
It’s not an efficient way to answer "how far is Jacksonville from Miami," but it’s the best way to see the state. Just be prepared for 35 mph speed limits and a lot of drawbridges.
Breaking Down the Stops
If you’re doing the drive in one go, you need a strategy. The "halfway point" is usually around the Vero Beach or Fort Pierce area.
- The 100-mile mark: You're passing Daytona. You feel great. Life is good.
- The 200-mile mark: You’re near Melbourne. Your back starts to hurt. You realize you still have 150 miles to go.
- The 300-mile mark: You’re in the Jupiter/West Palm area. The traffic is now officially insane.
The transition from "North Florida" (which feels more like Georgia) to "South Florida" (which feels like a different country entirely) happens somewhere around Port St. Lucie. The trees change. The air gets thicker. The license plates start coming from everywhere except Florida.

Brightline: The New Contender
As of now, the Brightline high-speed rail connects Miami to Orlando. While it doesn't go all the way to Jacksonville yet, many people are choosing to drive from Jax to Orlando (about 2 hours), park, and then take the train down to Miami.
It sounds counterintuitive to drive two hours just to get on a train, but if you want to avoid the stress of South Florida traffic, it’s a valid "hack." You get to drink a cocktail and use Wi-Fi while someone else navigates the chaos of the Golden Glades Interchange.
Things That Can Ruin Your Timeline
- Space Launches: If NASA or SpaceX is sending something into orbit, I-95 near Titusville becomes a parking lot. Check the launch schedule.
- Bike Week: If it’s March and you’re driving through Daytona, add an hour for the sheer volume of motorcycles.
- Summer Rain: These aren't showers; they are walls of water. In July, you will likely hit a storm so heavy everyone pulls over under an overpass. This can add 30 minutes to your trip instantly.
- Miami Sports: If the Heat or the Dolphins are playing, the final 20 miles of your journey will be the hardest.
Final Logistics
When you're planning this, don't just trust the "blue line" on your phone. Florida’s geography is deceptively long. Jacksonville is the largest city by land area in the contiguous US, and Miami is a sprawling megalopolis. You aren't just going city to city; you're traversing two different climates and three distinct cultural zones.
Actionable Next Steps:
- Check the FDOT (Florida Department of Transportation) alerts before leaving Jacksonville to see if there are major closures in the "Space Coast" section of I-95.
- Download the SunPass app. Even if you don't have a transponder, you can register your plate to avoid the "toll-by-plate" upcharges that rental car companies love to hit you with.
- Time your departure. Aim to leave Jacksonville either very early (5:00 AM) or after 10:00 AM. If you leave at 7:00 AM, you’ll hit Jax traffic leaving, and South Florida traffic arriving. Both are miserable.
- Fuel up in Palm Coast. Gas prices tend to spike as you get closer to West Palm Beach and Miami. Fill the tank while you’re still in the "cheaper" part of the state.
The distance is manageable, but it’s a full day’s commitment. Pack some snacks, find a long podcast, and keep an eye on the gas gauge. You'll get there eventually.
