How do Detroit and Key West compare?
These two cities share a country and not much else — Detroit is a Great Lakes comeback story 1,500 miles north of Key West's southernmost-US tropical outpost. Detroit is Motown Museum's Studio A, the Diego Rivera Industry Murals at the DIA, Belle Isle's Olmsted park, chili-cheese coneys at American Coney Island until 2 AM, and a downtown with the Q-Line streetcar tying it together. Key West is the inverse — a 4-mile-long island where Mallory Square's nightly sunset celebration draws fire-eaters and bagpipers, Hemingway's six-toed cats wander the writer's house, and the smell of conch-fritter oil hangs over Duval Street at 11 PM.
Mid-range $180 in Detroit against $350 in Key West — Key West runs almost 2x because everything ships in via the Overseas Highway. A coney lunch in Detroit is $12; a yellowtail snapper dinner at Louie's Backyard with Atlantic-side sunset hits $80 before drinks. Detroit wins on cost, museums (DIA, Henry Ford, Motown), and Lake Erie summer access; Key West wins on walkability (5/5), nightlife (Duval Street goes until 4 AM), key lime pie at Kermit's, and snorkeling reef trips to Dry Tortugas National Park.
Practical tip: Key West peaks December through April (book 3 months ahead — hotel rates spike for snowbirds); Detroit peaks May-October before lake-effect winters. They combine awkwardly because of the 1,500-mile diagonal — most travelers pair Key West with Miami (3.5-hour drive up the Overseas Highway) and Detroit with a Mackinac or Windsor day-trip.
💰 Budget
🛡️ Safety
Detroit
Detroit's national reputation for crime is dated — overall crime is down ~50% from the 2010 peak, and the downtown / Midtown / Corktown / New Center / West Village core (where 95% of visitors spend their time) has crime rates comparable to other big-city tourist areas. The danger zones are specific neighborhoods on the East Side and parts of the North End that visitors have no reason to visit. Drive (or rideshare) between neighborhoods rather than walking long distances at night, and you will be fine.
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.
🌤️ Weather
Detroit
Detroit has a humid continental climate — warm, humid summers (July averages 28°C / 82°F daytime), cold snowy winters (January averages -3°C / 27°F daytime, lows often -10°C, occasional polar vortex events to -20°C+). Lake Michigan moderates things slightly but Detroit gets the full Midwest weather. Spring is short and wet; fall is the prettiest season with peak color late October. Summer humidity is real but not Houston-level.
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.
🚇 Getting Around
Detroit
Detroit was built for cars — public transit is functional but limited compared to peer cities, and most visitors will use a combination of rideshare (Lyft/Uber, both cheap and reliable here), the QLINE streetcar on Woodward, the People Mover elevated loop downtown, and walking within the central neighborhoods. Renting a car is genuinely useful for trips to Dearborn (Henry Ford Museum), Hamtramck, or anywhere in the suburbs.
Walkability: Within the central neighborhoods (Downtown / Greektown / Corktown / Midtown / Eastern Market) Detroit is genuinely walkable — flat terrain, wide sidewalks, short city-block grid. Between neighborhoods you will want a rideshare or the QLINE; the gaps are larger than in compact cities like Boston or Chicago. The Riverwalk and the Dequindre Cut greenway are dedicated pedestrian/bike infrastructure linking several core neighborhoods.
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.
