Driving From Maine to Miami Is a Lot of Ground and Most People Underestimate the Heat
You want to know how to do this properly. I've done the drive north to south and back twice, once in July and once in February. The February run was significantly less painful. Florida stretches roughly 500 miles from the Georgia border down to the tip of Miami, though if you're driving all the way to the Everglades City side you're looking at closer to 600 depending on your exact start and end points. The interstate is straightforward. Take I-75 south or I-95 south depending on which coast you prefer. I-75 is faster and cheaper in tolls. I-95 has more traffic and more lights but runs closer to the beach towns if that matters to you. The common mistake people make is treating this like a two-day drive. It's not. You need at least four days minimum if you want to stop at anything other than gas stations and fast food. Book your motels in advance for the middle sections. Okeechobee and Sebring are where you run into issues in peak season. Hotels fill up because it's close enough to Orlando that weekend trippers swamp the area. I always book these spots on a separate calendar alert two weeks out. Same thing going through the Panhandle if you're coming from I-10 west before dropping south. Fuel strategy matters more than people think. The stretch between Lake City and Ocala has long gaps between price drops. Fill up in Lake City. Gas there is usually 20 to 30 cents cheaper per gallon than the I-75 corridor further south. In the Keys, gas jumps again. Fill up in Key West before heading back or just accept that you will pay a premium and move on. Don't try to micromanage every fill-up. You'll waste more time than you'll save.
What You Actually See When You Drive This Route
Starting from the north at the Georgia line, you hit Tallahassee first. It's a decent town but not worth a long stop unless you're hungry. Grab something, keep moving south. The landscape changes gradually. You get into the piney woods around Lake City, then the flattening farmland near Ocala. The Ocala National Forest runs alongside I-75 for about 40 miles. If you have time, take exit 271 and drive through. It's not spectacular but it breaks up the monotony of the interstate. Swampscott near Fort Lauderdale is where people tend to slow down because traffic gets real. The interchange with I-95 and the toll road merge is messy during rush hour. Leave before 7 AM or after 8 PM if you can. The section between Fort Myers and Naples on I-75 has been widened recently but the construction zones still cause slowdowns. Expect delays of 20 to 40 minutes if you hit one. The Keys themselves are the tricky part. Seven Mile Bridge is beautiful but it's also a bottleneck. During spring break and holiday weekends, traffic crawls from Marathon to Key Largo. I timed it once at 12 miles per hour for about 90 minutes. The workaround is to take the ferry from Crystal River to Key West if you're willing to commit to it. It takes longer overall but you skip the bridge entirely and it's a legit experience instead of sitting in a parking lot on wheels.
Water and Food Logistics
Don't skip water. The humidity in southern Florida hits differently than anywhere else in the continental US. I learned this on the July run. I thought I was fine until mile 380 when my forehead started sweating through my shirt just sitting in the car. Keep cold water in the cup holders. Not ice water. Just consistently cold. Your brain makes worse decisions when you're mildly dehydrated and you'll make bad exits if you're not careful. There's a rest area every 20 miles or so on I-75 south of Ocala. Use them. They have functioning AC and bathroom facilities that aren't horrifying. Food-wise, avoid the tourist traps in Big Cypress. The diners there markup prices by about 40 percent compared to what you'd pay in Miami. Stop in Clewiston on the way if you need a real meal. It's a small town but the Cuban sandwiches are reasonable and fresh. Further south, Miami has every option. The trick is to eat before you get into downtown traffic. You'll spend more time looking for parking than you will eating if you wait.

A Problem I Hit and How I Worked Around It
On my second run through, I got caught in a flash flood near the Tamiami Trail exit. The road closed for about three hours and there was no detour signposted properly. GPS kept trying to route me back through flooded intersections. I ended up pulling over at a truck stop off I-75 and waiting it out. When the water receded, I took exit 3 for US-41 south instead of trying to re-enter I-75 directly. It added about 45 minutes but it was the only viable path through. I keep a printed map of the southern Florida exits now. Not because I don't trust phones, but because cell service drops in the Big Cypress reservation area and I don't want to be making decisions without navigation help. If you're driving in June or September with a vehicle that doesn't handle heat well, this trip becomes miserable. Air conditioning failure in the Keys is not a joke. There are no repair shops within 30 miles of most of the island chain. If your car overheats down there, you're calling a tow and waiting. I've seen people stranded for six hours waiting on roadside assistance. Check your cooling system before you leave. Raditor hoses, thermostat, coolant level. Five minutes of inspection saves you a day of delay. Another scenario where this doesn't work is solo driving with a tight schedule. The Florida Turnpike tolls add up fast. From Opa-locka to the Florida City gate alone is about $7. Add in the I-75 express lanes and you're looking at $15 to $20 in tolls for a one-way trip through the southern section. Budget for it or you'll be cutting corners somewhere else. If you're on a strict timeline, fly into Miami and rent a car for the southern portion instead. It costs more upfront but you avoid the wear and tear and the stress of a long haul.
The most honest assessment is that this drive is achievable but not romantic. The scenery is flat. The traffic is heavy in patches. The heat is real. But it's a reasonable way to see the state if you plan around the variables instead of fighting them. Four days minimum. Early morning starts. Water on hand. A backup navigation plan. Do those things and you'll get across without too many headaches.
