How do Key West and Miami compare?
Every Miami visitor with a free three days faces the Florida Keys question — drive 160 miles down the Overseas Highway to the southernmost point in the continental US, or stay in the South Beach Art Deco bubble. Miami is the Latin-American gateway — Ocean Drive's pastel Deco hotels, Wynwood Walls' street art, Cuban cafecitos in Little Havana, Vizcaya gardens, and a nightlife scene that runs 11 p.m. to 5 a.m. across LIV, E11EVEN, and rooftops. Key West is the 25,000-person seceded Conch Republic at the end of the highway — the 1.25-mile Duval Street, Hemingway's Whitehead Street home with the six-toed cats, the nightly Mallory Square sunset celebration, and Fort Zachary Taylor's quiet beach beyond the Old Town crowds.
Transit is the famous drive — 3h 30min on US-1 through Key Largo, Islamorada, and Marathon, with the 7-Mile Bridge as the photogenic centerpiece. Or fly American or Silver from Miami to Key West (EYW) in 50 minutes for around $250, which makes sense if you only have two nights. Mid-range budgets are nearly tied: $305 a day in Miami versus $350 in Key West — the gap shows up in hotels, where Old Town guesthouses are scarce and command a premium December through April. Miami wins on food variety, nightlife, museum scale, and beach length. Key West wins on walkability, quirky island scale, the Hemingway literary thread, and a daily 6 p.m. sunset ritual that has been a 50-year-old performance with jugglers and tarot readers at the harbor.
Both peak December through April for the dry, warm window — and both empty out from May through October, when humidity climbs and hurricane risk runs from June onward. The standard combo is three nights Miami, then drive to Key West for two more, with a Bahia Honda State Park beach stop on the way. Pro tip: book a Yankee Freedom day trip from Key West to Dry Tortugas National Park — the 70-mile catamaran ride to Fort Jefferson runs $215 with breakfast, lunch, snorkel gear, and the historic-fort tour included, and the reef there genuinely beats anything you can dive off Key West proper. Pick Miami for nightlife, food, and the Latin-American city pulse; Pick Key West for southernmost-US quirk and the Hemingway sunset week.

🛡️ Safety
Key West
Key West is generally a safe small city for tourists. Old Town is well-policed and busy; the main risks are alcohol-related incidents (Duval Street late-night), aggressive scooter rentals on busy streets, sun exposure, and the seasonal hurricane risk. Petty theft from rental scooters and unattended beach belongings does occur. The island's relaxed, party-oriented culture means common sense is your best safety tool.
Miami
Most tourist areas of Miami — South Beach, Wynwood, the Design District, Coconut Grove, Coral Gables, Key Biscayne — are safe for visitors. Petty theft, car break-ins, and pickpocketing are the main concerns. Some neighborhoods north and west of downtown have higher crime and tourists have no reason to go there. Spring break season (March) and major events bring rowdy crowds to South Beach.
🌤️ Weather
Key West
Key West has a tropical savanna climate moderated by surrounding water — temperatures stay narrowly between 18°C (winter low) and 32°C (summer high) all year. There is a wet season (May–October, with afternoon thunderstorms and hurricane risk) and a dry season (November–April, which is also peak tourist season). Hurricane risk is real — Hurricane Irma in 2017 caused major damage to the Lower Keys.
Miami
Miami has a tropical monsoon climate — warm to hot year-round, with a distinct wet season (May-October) and dry season (November-April). Ocean breezes moderate coastal temperatures. The "dry season" is the peak tourist season with near-perfect weather, while summer brings heat, humidity, and thunderstorms.
🚇 Getting Around
Key West
Key West Old Town is small (about 2 miles by 4 miles total island) and the historic centre is almost entirely walkable. Bicycles are the favourite local transport — flat terrain, dedicated bike lanes, and bike racks everywhere. The Duval Loop bus is free; Uber and Lyft operate but are more expensive than in Miami. Renting a car for the week is unnecessary unless you're visiting other Keys; parking in Old Town is scarce and expensive ($4-8/hour, $25/day in city lots).
Walkability: Old Town is one of the most walkable small-city centres in America — flat, compact, shaded by tropical canopy, and full of architectural detail. The full Duval Street walk takes 25 minutes end to end. Bicycles extend the comfortable range to the entire island.
Miami
Miami is a sprawling, car-centric city. Public transit exists but is limited compared to New York or Chicago — the Metrorail runs a single main corridor, the Metromover is a free downtown people-mover, and buses fill gaps. Rideshare is extremely popular, and many visitors rent cars to reach the Everglades, the Keys, or Fort Lauderdale.
Walkability: South Beach is very walkable — tight grid, flat, with Lincoln Road pedestrianized and Ocean Drive full of life. Wynwood, the Design District, and Coconut Grove are also walkable neighborhood-scale. Between neighborhoods, however, distances are long and rideshare is usually necessary. Avoid walking across causeways.
