Plan a road trip from Miami to Key West with this stop-by-stop guide to the Florida Keys, from Homestead to the Overseas Highway's end.
A road trip from Miami to Key West is one of the most scenic drives in the United States, stringing together mangrove islands, bridges over open water, and small towns that each have their own personality. The route follows US Highway 1 south out of Miami, across the Overseas Highway, and out to the last stop on the map. Here’s how to think through the stops, the pacing, and the practical side of planning it.

The Route, Town by Town
The classic drive runs south from Miami through Homestead, then down the island chain through Key Largo, Islamorada, Marathon, and Big Pine Key, before ending at Key West. Each of these is a natural place to slow down, not just a dot to pass through.
What Each Stop Is Known For
Miami mixes Latin culture, Art Deco architecture, and Atlantic coastline, from the energy of Wynwood to the sand of South Beach. It’s a city built for lingering — home to about 442,241 people, and travelers commonly spend anywhere from 3 to 6 days here before even starting south. If you have time before you go, Bayside Marketplace and the Calle Ocho Walk of Fame are easy ways to get a feel for the city.
Homestead is the quieter gateway to Everglades and Biscayne National Parks, with roadside farm stands, tropical fruit groves, and a strong Latino food scene. With a population of around 80,737, it’s a practical, low-key stop most travelers spend 2 to 4 days around if they’re using it as a base for the parks.
Key Largo, population roughly 10,433, is where the drive starts to feel like the Keys — a diving and snorkeling hub with marine parks, glass-bottom boat tours, and waterfront restaurants.
Islamorada calls itself the “Village of Islands,” and it earns the fishing-town reputation with boutique shops and laid-back waterfront taverns. It’s home to about 7,107 people.
Marathon sits roughly in the middle of the chain, best known for the Seven Mile Bridge and its marine rescue attractions — a natural halfway stop to stretch your legs before the final push south.
Big Pine Key, population around 5,032, is famous for the National Key Deer Refuge, where you can spot the tiny, endangered key deer in the wild.
Key West is the finish line: Duval Street, sunset crowds at Mallory Square, and the southernmost point marker, all with an unmistakable end-of-the-road feel.
How Long to Plan For
There’s no single right length for this drive — it depends on how much of Miami and the Keys you want to see versus how quickly you want to reach Key West. Some travelers treat it as a long day trip; most spread it over several days to actually stop at the islands along the way rather than just drive past them. If you’re mapping this out for the first time, a step-by-step planning guide is worth a read before you lock in dates.
Timing and the Road Itself
The Overseas Highway is a single road for long stretches, so traffic and weather matter more here than on a typical interstate drive. Hurricane season runs through the fall, and afternoon storms are common in summer, so building some flexibility into your schedule pays off. Bridges mean fewer places to pull off than you might expect, so plan fuel and food stops before you’re down to fumes — and pack accordingly; a good road trip snack list goes a long way on a route with long gaps between towns.

Journey Builder's auto-schedule usually turns your picks into a day-by-day plan in 1–3 minutes.
Heads-up
Afternoon storms and hurricane season can slow this single-road route, so build flexibility into your schedule.
Where Journey Builder Fits In
A drive with this many worthwhile small stops is exactly where a trip can get overcomplicated fast — too many towns to weigh against each other, and too little time to research each one by hand. Journey Builder ranks the towns along your route and suggests stops, showing whether each is right on your route or how far off it is and how big a detour it adds, so you can decide which islands are worth the stop. It also suggests how many nights to spend at each one and lets you choose your roads — sticking to the fastest route or favoring fewer highways — and once you’ve picked your stops, its auto-scheduler builds a day-by-day plan around your wake-up time, bedtime, drives, and meals, usually in 1–3 minutes. You can see how the route-to-plan process works or browse how it helps you choose what to do, eat, and where to stay at every stop.
