The southernmost city, not a quick side trip
Key West sits at the end of the Overseas Highway, the last town before the road stops. It’s the southernmost point in the continental United States, closer to Cuba (about 90 miles) than to most of the rest of Florida. That position is exactly why it feels different from anywhere else in The Florida Keys: a real town with a fishing-village core, wrapped in a tourist economy built around sunset, seafood and a permissive, slightly theatrical atmosphere on Duval Street.
The single fact worth internalizing before anything else: Key West is not a short excursion. From Miami it’s roughly 160 miles (257 km) by US-1 and the Overseas Highway, which translates to 3h30 to 4 hours of driving in each direction without stops — more once you add traffic, especially on weekends and around holidays. A round trip in a single day is close to 8 hours behind the wheel or on a bus, for whatever time is left in between. It’s possible, plenty of people do it, but it’s worth being honest about the trade-off rather than pretending it’s a quick hop.
This page covers Key West itself. For the full run down the Keys — Key Largo, Islamorada, Marathon and the bridges between them — see the The Florida Keys: Key Largo to Key West, mile by mile region page.
Getting here: drive it, bus it, or fly
Three realistic ways to reach Key West from the Miami area:
| Option | Time each way | Notes |
|---|---|---|
| Self-drive (US-1 / Overseas Highway) | 3h30-4h | 42 bridges, including the Seven Mile Bridge near Marathon; no shortcuts |
| Organized bus day trip | 3h30-4h, fixed schedule | Seat included, driving stress removed, but a long day |
| Fly into EYW (Key West International) | Under 1 hour | More expensive, useful if time matters more than budget |
If you’re driving yourself and staying only a day, budget the return trip carefully — leaving Key West at dusk means arriving back in Miami late, tired, after dark. A guided day trip removes that decision: a Small Group Key West 1 Day Tour or the small-group day tour from Miami handles the driving both ways and usually builds in stops. Departures from Fort Lauderdale exist too, on a similar drive time; see the Fort Lauderdale to Key West day trip if that’s the closer airport. For the mechanics of the drive itself — where to stop, what the bridges are like, how long the Seven Mile Bridge really takes — see driving the Overseas Highway to Key West and the head-to-head in driving vs. bus tour to Key West.
Duval Street and downtown
Duval Street runs from the Gulf side to the Atlantic side of Old Town, about a mile of bars, restaurants, souvenir shops and live music that gets louder as the afternoon goes on. It’s the spine most visitors walk at least once, and it’s genuinely fun in short doses — a few blocks of it, a stop for a drink, a look at the historic wooden storefronts — rather than as an all-day activity. Side streets off Duval hold quieter guesthouses and the residential character that gives Old Town its charm away from the main strip.
The Southernmost Point buoy, a concrete marker near the corner of Whitehead and South streets, is the photographed landmark: a striped buoy claiming to mark the southernmost point in the continental US (the actual southernmost point is on nearby restricted land, but the buoy is the one everyone photographs). Expect a line for the photo, especially midday and around cruise-ship arrivals — early morning is calmer.
For a broader look at what’s worth doing beyond the headline sights, things to do in Key West breaks activities out by category, from boat tours and cruises to snorkeling and diving.
Mallory Square at sunset
Mallory Square, on the Gulf side of Old Town, hosts the Sunset Celebration every evening: street performers, food carts and a crowd that gathers specifically to watch the sun go down over the water. It’s touristy and it knows it, but the sunset itself is the real draw, and arriving 30-45 minutes early secures a decent spot along the seawall. It’s free to attend; performers work for tips.
For a view of the same sunset from the water rather than the seawall, a boat-based option changes the experience — see Key West boat tours and cruises for the range, from catamaran sunset sails to something more active like the tiki-style party boat rental.
The Hemingway House
Ernest Hemingway lived in a Spanish Colonial house on Whitehead Street through much of the 1930s, and it’s now a museum: guided tours cover the house, his writing studio, and the descendants of his famously six-toed cats that still live on the grounds. It’s one of the more substantive indoor stops in Key West and works well as a mid-afternoon break from the sun. Expect an entry fee and a wait during peak hours; the earlier in the day, the shorter the line.
The house is also the easiest entry point into a wider thread that runs through the whole town — bars Hemingway drank in, the boxing ring he sparred in, the writers who followed him to Key West afterward. For the fuller story rather than just the museum stop, see Hemingway in Key West.
Getting out on the water
Key West’s setting — surrounded by reef and open water — makes boat-based activities as central here as walking Duval Street. Options range from relaxed to active:
- Snorkeling and diving on nearby reef, covered in Key West snorkeling and diving
- Dolphin-watching and other wildlife trips, in Key West dolphin and wildlife tours
- Jet ski and other water sports, in Key West jet ski and water sports
- Paddling the calmer backcountry water, in Key West kayak and paddleboard
- A more social, floating-bar style outing on the family sandbar adventure
Food and drink are their own reason to linger — see Key West food and drink tours for guided options, and history and ghost tours for the town’s wrecking, cigar-making and literary past told as a walking tour after dark. Key lime pie is the one dish everyone tries at least once in Key West — it’s the town’s signature dessert, and quality varies a lot between the tourist-strip versions and the places locals actually recommend; see the best key lime pie in the Florida Keys for where it’s worth stopping.
Key West vs. a shorter stop at Key Largo
Not every visitor needs to go all the way to Key West. If the drive time is the sticking point, Key Largo sits roughly at the start of the Keys, well under half the distance from Miami, and covers snorkeling and reef access without the full-day commitment. It’s a genuinely different trip — more reef and water time, less town and nightlife — and the head-to-head comparison in Key West vs. Key Largo day trip lays out which one fits a given amount of time and interest better before booking anything.
Gateway to the Dry Tortugas — but not by road
Key West is where the Overseas Highway ends, and it’s also the only practical departure point for Dry Tortugas National Park, about 70 miles further west. There is no road there. The park’s Fort Jefferson, a 19th-century fortress on Garden Key, is reachable only by the official park ferry, by seaplane, or by private or chartered boat — never by car, and never as a side trip you can improvise on the day. The ferry in particular sells out weeks in advance in high season, so it needs booking ahead if it’s on the itinerary. Full detail, pricing and how to plan around it: Dry Tortugas National Park guide.
Because the Dry Tortugas is a full-day trip on its own — the ferry alone runs several hours each way — it isn’t something to combine with a single day in Key West. It effectively requires an overnight stay in Key West the night before.
Day trip or overnight: an honest comparison
| Day trip from Miami | Overnight in Key West | |
|---|---|---|
| Time on the road | 7-8 hours round trip | Same drive, but spread over two days |
| Time actually in Key West | 4-6 hours | 24-48+ hours |
| Sunset at Mallory Square | Rushed, if the schedule allows it at all | Relaxed, no departure deadline |
| Dry Tortugas possible | No | Yes, with an early ferry departure |
| Cost | Lower — no extra lodging | Higher — a Key West hotel night, on top of the drive |
If Duval Street, the buoy and the Hemingway House are the goal and time is tight, a guided day trip such as the Key West day trip with optional activities covers the essentials without an overnight stay. For a longer look at the wider Keys en route — snorkeling at Key Largo, a stop in Islamorada — a multi-stop itinerary makes more sense than a straight there-and-back; see seven days Miami and the Florida Keys or the shorter Miami to Key West road trip.
Practical notes
- Parking: Old Town parking is limited and metered; many visitors park once and walk or use a bike or scooter rental for the day.
- Weather: hurricane season runs June 1 to November 30 (NOAA), with the highest activity from August through October. It doesn’t mean a storm is likely on any given date, but flexible bookings and travel insurance are worth having in that window.
- Sun and heat: little shade on Duval Street at midday; reef-safe sunscreen is worth using given the coral offshore.
- Combining stops: Key West pairs naturally with a wider Everglades-to-Keys route — see everglades day trip from Miami if the Everglades are part of the same trip, or the broader 3 Day Florida Getaway Miami Everglades Key West Snorkel style itinerary via the Fort Lauderdale-to-Key West day trip for those coming from the north side of Miami.
Common questions about visiting Key West
How far is Key West from Miami?
About 160 miles (257 km) by US-1 and the Overseas Highway, which takes 3h30 to 4 hours to drive in each direction without stops. Traffic, especially near Miami and on weekends, regularly adds to that.
Can you visit Key West as a day trip from Miami?
Yes, but it means roughly 7-8 hours of round-trip travel for a few hours in town. Guided bus day trips exist and handle the driving, but an overnight stay gives noticeably more time to actually see the town, including the Mallory Square sunset without a departure deadline.
How do you get to the Dry Tortugas from Key West?
Only by official park ferry, seaplane, or private or chartered boat. There is no road connection — the Overseas Highway ends at Key West — and the ferry should be booked well in advance, especially in the winter high season.
Is the Southernmost Point buoy the actual southernmost point in the US?
It’s the photographed marker most visitors associate with the title, near Whitehead and South streets. The true southernmost accessible point in the continental US is nearby but on restricted land; the buoy is the practical stand-in everyone stops at.
What’s the best time of day to see Mallory Square?
Arrive 30-45 minutes before sunset to get a spot along the seawall before the crowd builds. The Sunset Celebration itself is free; street performers work for tips.
Is Key West safe and easy to walk around?
Old Town is compact and walkable, with Duval Street as the busiest strip. Like any nightlife-heavy area, it gets rowdier late in the evening, but it’s generally straightforward for visitors on foot or by bike.
How much does a day in Key West cost?
Roughly $80-200 per person once transport, a meal or two, and one paid attraction (like the Hemingway House or a boat excursion) are added in; a full-day guided tour with transport included often lands in that range depending on what’s built in. Check the current listing on GetYourGuide or Viator for the day’s price rather than relying on a fixed figure.
Does hurricane season affect a Key West trip?
Hurricane season runs June 1 to November 30, with August through October the most active stretch. It doesn’t rule out a visit, but flexible bookings and travel insurance are sensible in that window, and it’s worth checking forecasts in the days before departure rather than months ahead.
