Salt Lake City vs Denver

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.

Denver

Denver has a semi-arid, high-altitude climate with 300+ days of sunshine a year and very low humidity. The altitude and dry air make the sun intense — UV levels are routinely "very high" even in winter. Weather is famously volatile: 70°F one afternoon and snowing the next morning is standard. Afternoon thunderstorms roll off the Front Range most summer days; big snowstorms punctuate winter. Hydrate aggressively regardless of the season — the combination of altitude and dry air dehydrates visitors fast.

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.

Denver

Denver is a sprawling car-oriented metro with a workable (by US standards) light rail and commuter rail network operated by RTD. The A Line train from Union Station to the airport is one of the best airport transit links in any US city. Core neighborhoods (LoDo, RiNo, Capitol Hill, Wash Park) are walkable individually, but connecting them typically means rideshare or transit. Rideshare is cheap and ubiquitous.

Walkability: Denver is walkable within neighborhoods but sprawling overall. LoDo, RiNo, Capitol Hill, Cherry Creek, and Wash Park each work on foot. Connecting them means rideshare, transit, or cycling. The altitude makes the first 24-48 hours of walking unexpectedly tiring — go slower than you think you should. Summer sun at 5,280 ft is aggressive even in cooler temperatures.
