How do Key West and Salt Lake City compare?
These two USA picks share almost nothing except a passport — and that's exactly why the choice is interesting. Key West is the southernmost end of US-1, a 4-square-mile reef-and-rum island where Mallory Square's nightly sunset celebration includes a guy juggling chainsaws and Hemingway's six-toed cats prowling the Whitehead Street museum. Salt Lake City is a 4,200-foot grid against the Wasatch Front, where you can be skiing 8,000 vertical feet at Snowbird 35 minutes after leaving downtown and back for a Beehive Distillery old-fashioned by 6 PM.
Mid-range nights run $350 in Key West versus $280 in SLC — Key West's island logistics inflate everything, and a conch-fritter dinner at Blue Heaven runs $55 against a $35 dinner at Red Iguana in SLC. Key West wins on walkability (the whole island is bikeable), nightlife, and quirk; SLC wins on nature access, transit (TRAX light rail actually works), and cleanliness. The Mighty Five — Arches, Canyonlands, Capitol Reef, Bryce, Zion — are all within five hours of SLC. Key West's reef is a 30-minute boat from Mallory.
Time matters: Key West peaks December–April when the Northeast freezes, and hits hurricane season June–October. SLC peaks for skiing (December–March powder) or canyon shoulder season (April–May, September–October) — July's high-90s heat blunts the city. A Delta 5-hour direct from JFK reaches both. Pick Key West if conch fritters, Hemingway House, and reef-snorkel afternoons trump alpine peaks. Pick Salt Lake City if Wasatch powder days, Mighty Five access, and Antelope Island bison beat island bar-crawls.

🛡️ 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.
Salt Lake City
Salt Lake City is one of the safer large US cities — overall violent crime rates are below the national average for cities of similar size, and tourist neighborhoods (Downtown, Temple Square, the Avenues, Sugar House, 9th & 9th, University District) are comfortable day and night. The city's primary issues are property crime (car break-ins) and concentrated homelessness in pockets of downtown (Rio Grande district, around the central library). Solo female travellers report Salt Lake as comfortable.
🌤️ 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.
Salt Lake City
Salt Lake City has a semi-arid continental climate with four distinct seasons — hot dry summers (highs 32–35°C with low humidity), cold snowy winters (lows -7°C, the famous "lake-effect" snow that's among the lightest and driest in the world), and pleasant transitional spring and autumn. The city sits at 4,265 feet (1,300m) elevation; the Wasatch Mountains rise to 11,000+ feet immediately east. The famous "Greatest Snow on Earth" tagline is genuinely true — Wasatch snow is unusually dry due to the lake-effect mechanism.
🚇 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.
Salt Lake City
Salt Lake City is unusually walkable and transit-friendly for a Western US city — the TRAX light rail and FrontRunner commuter rail are extensive, downtown is flat with a perfect grid, and the airport is connected by light rail. Mountain trips (Park City, Snowbird, Alta) require a car or paid shuttle. The city grid is so logical (numbered streets radiating from Temple Square) that navigation is trivial after one day.
Walkability: Salt Lake is unusually walkable for the western US — flat downtown, perfect numbered street grid (which makes navigation trivial), and walkable density between Temple Square, the City-County Building, the Capitol, and the central business district. The city is far more walkable than Phoenix, Las Vegas, Denver, or Albuquerque. Mountain access requires a car or shuttle; everything inside the I-15/I-215 ring is fine on foot/transit.
