Snow on the ground in Western New York. It’s gray. It’s slushy. You’re scraping ice off a windshield at 6:00 AM, wondering why on earth you live where the air hurts your face.
Then you think about it. The southernmost point. That weird concrete buoy. Key lime pie that isn't neon green.
The trip from Buffalo to Key West is basically a 1,500-mile escape mission. It's a transition from the Rust Belt’s industrial grit to the salt-air relaxation of the Florida Keys. Honestly, it’s one of the most underrated long-haul drives in the Eastern U.S. because people usually just hop on a flight and miss the weird, wonderful transition of the American landscape. You’re swapping the Great Lakes for the Gulf Stream. Buffalo's beef on weck for Key West's conch fritters.
It's a long way. Let's not sugarcoat that.
The Logistics: Driving vs. Flying Buffalo to Key West
Most people look at the map and immediately head to Expedia. I get it. A flight from Buffalo Niagara International (BUF) to Key West (EYW) usually involves a layover in Charlotte or Atlanta. You're looking at maybe five to seven hours total if the connection isn't a nightmare.
But if you drive? That's roughly 22 to 24 hours of pure seat time.
Why would anyone do that? Because the I-95 corridor—while often a headache—is a rite of passage. If you take the inland route through the mountains of West Virginia and Virginia via I-79 and I-81, the scenery is actually stunning. You avoid the madness of DC and Baltimore. You see the Appalachian spine before hitting the flat, humid expanse of the South.
What to Expect on the Road
The route usually funnels you down I-79 South out of Buffalo. You hit West Virginia. It’s hilly. It’s green. Then you pick up I-81 through the Shenandoah Valley. This is the "secret" way for smart travelers. It’s way less stressful than the coastal highway.

Eventually, you’ll merge toward I-95 in South Carolina or Georgia. That’s where the air changes. You’ll feel it. The heater goes off. The windows roll down. By the time you hit Jacksonville, you realize you've crossed a threshold.
Breaking the Journey: Where to Actually Stop
Don't try to do this in one go. You'll arrive in Key West looking like a zombie, and nobody wants to start a vacation with a back ache and a caffeine crash.
Savannah, Georgia: It’s almost perfectly positioned about two-thirds of the way down. The Spanish moss is a vibe. Walk around Forsyth Park. Eat something that involves grits. It prepares your palate for the South.
St. Augustine, Florida: If you have an extra four hours, stop here. It’s the oldest city in the U.S. It feels European in a way that Buffalo definitely does not.
Miami/Homestead: This is the gateway. This is where the "real" drive begins. Once you hit Florida City and see the signs for the Overseas Highway, the energy shifts.

This is the climax of the Buffalo to Key West journey. Once you leave the mainland, you’re on US-1. It’s a series of 42 bridges.
The Seven Mile Bridge is the heavy hitter. It’s just you and the turquoise water. If you’re lucky enough to hit this at sunset, you’ll forget all about the snow back in Cheektowaga.

Key Largo and Islamorada
Most people rush through these to get to the end. That's a mistake. Stop at Mrs. Mac’s Kitchen in Key Largo. It’s legendary for a reason. Get the pita with the mahi-mahi. It’s simple, fresh, and exactly what you need after 20 hours of highway food.
In Islamorada, go to Robbie’s. You can feed tarpon. They’re massive, prehistoric-looking fish that will jump out of the water to grab a baitfish from your hand. It’s touristy as heck, but honestly, it’s fun.
Finally Reaching Key West: The Culture Shock
Key West is weird. It’s not like the rest of Florida. It’s closer to Havana than it is to Miami.
Coming from Buffalo, the first thing you’ll notice is the pace. Everything slows down. People bike everywhere. There are chickens—actual wild roosters—walking into the CVS and strutting down Duval Street.
What Most People Get Wrong About Duval Street
Duval is the famous strip. It’s loud. It’s got Sloppy Joe’s and Irish Kevin’s. But if you spend all your time there, you’ve missed the point of the island.
Go to the "Old Town" neighborhoods. Look at the gingerbread architecture. These houses were built by shipbuilders in the 1800s. They don't use nails; they use wooden pegs. It’s craftsmanship that rivals the old cathedrals in Buffalo, just in a much saltier environment.
The Food Reality Check
You’re going to want Key Lime Pie. Avoid the stuff that’s bright green. Real Key Lime Pie is pale yellow because the juice of Key limes is yellow, not green. Kermit’s is the classic choice, but Blue Heaven does a version with a mountain of meringue that is basically a structural engineering feat.

And eat the pink shrimp. They’re caught locally. They’re sweeter than the stuff you get at the Wegmans seafood counter back home.
The Best Time to Make the Trip
Timing is everything.
If you go in August, you will melt. The humidity in the Keys is a physical weight. It’s like wearing a warm, wet blanket.
February and March are the sweet spots. While Buffalo is suffering through its third "false spring" and getting dumped with six inches of slush, Key West is a perfect 75 degrees. The trade winds keep it comfortable.
Hurricane Season (June to November) is the gamble. You might get a week of perfect glass-calm water, or you might get evacuated. Most locals just shrug it off until the sirens start, but as a visitor, you need to keep an eye on the NOAA forecasts.
Practical Insights for Your Buffalo to Key West Trek
- Tolls are real: If you drive, get an E-ZPass or a SunPass. Florida has moved to all-electronic tolling on many roads. If you don't have a transponder, you’ll get hit with "toll-by-plate" fees that add up fast.
- The "One Human Family" Philosophy: Key West’s official motto is "One Human Family." It’s an incredibly inclusive, quirky, and welcoming place. Leave the stress at the border.
- Parking is a Nightmare: Once you get to Key West, park the car and leave it. Rent a bike. The island is only 4 miles long and 2 miles wide. A car is a liability on those narrow streets.
- The Southernmost Point: Yes, the line for the photo at the buoy is long. If you want the shot without waiting two hours, go at 7:00 AM.
Traveling from Buffalo to Key West isn't just a change in latitude. It's a complete nervous system reset. You leave behind the heavy coats, the salt-corroded cars, and the gray skies. You trade them for coral reefs, Hemingway’s cats, and a sunset celebration at Mallory Square that happens every single night just because the sun went down.
Actionable Next Steps
- Check your route options: Decide if you want the scenic I-81 mountain drive or the faster I-95 coastal run. Download the GasBuddy app to track the massive price swings in fuel as you cross state lines.
- Book your Key West lodging early: The island is tiny. Spots fill up six months in advance for the winter peak. Look for "Conch House" B&Bs for a more authentic feel than the big resorts.
- Prep your vehicle: Before leaving Western New York, check your cooling system. Your car is about to go from 20 degrees to 80 degrees in a matter of two days. That's a lot of stress on the radiator and hoses.
- Pack light: You won't need anything heavier than a light hoodie for the evening breeze. Everything else is flip-flops and linen.
By the time you see the "End 1" sign on US-1, the Buffalo winter will feel like a distant, cold dream. You've made it to the end of the road. Literally. Enjoy the salt air—you’ve earned it.
