Denver

Denver operates as the undisputed gateway to the American Mountain West — DEN handles more than 80 million passengers annually and sits at the intersection of every major Rocky Mountain corridor, making it a practical launchpad rather than a terminus. The city's downtown core is compact and walkable, centered on the 16th Street Mall and Larimer Square, but the pace is distinctly mid-sized: unhurried enough that outdoor gear shops outnumber investment banks on the main drags. Architecture skews recent — the glass towers of the Central Business District arrived mostly after 1990, and the LoDo warehouse district provides the closest thing to accumulated patina, with red-brick buildings from the 1880s cattle-trade era converted into brewpubs and food halls. A week here means mornings in City Park or at the Denver Art Museum's Hamilton Building, afternoons deciding between Rocky Mountain National Park and Red Rocks Amphitheatre, and evenings in RiNo where the craft brewery density is among the highest per capita in the country.
