Las Vegas vs Denver

Las Vegas

Las Vegas has a hot desert climate with extreme temperature swings between summer and winter. Summers are brutally hot — June through August regularly sees highs above 40°C (104°F), with July averages around 42°C. Winters are mild and pleasant, with daytime highs around 15°C. Spring and autumn are the ideal windows: warm, dry, and comfortable. Flash floods are possible year-round but most common in late summer monsoon season.

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.

Las Vegas

Getting around the Strip is surprisingly challenging despite its apparent simplicity — the boulevard looks walkable but distances between resorts are much longer than they appear. A mix of the Las Vegas Monorail, the Deuce bus, ride-hailing apps, and your feet will cover most needs on the Strip. A rental car is strongly recommended for off-Strip destinations like Red Rock Canyon, Hoover Dam, and Valley of Fire.

Walkability: The Strip looks walkable on a map but is deceptive — the distance from Mandalay Bay to the Stratosphere is over 4 miles, and summer temperatures make outdoor walking dangerous. Between individual resorts in a cluster (e.g., Cosmopolitan to Bellagio), walking is fine. In summer, use the air-conditioned casino connectors and skywalks linking several properties. Downtown Fremont Street is very walkable within the Experience canopy.

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.
