A city a mile above the Rockies: Colorado's gateway, with craft breweries, Red Rocks Amphitheatre and ski resorts an hour's drive away.
Denver is the largest city and capital of the US state of Colorado, spread across the Great Plains at the eastern foot of the Rocky Mountains. Sitting at exactly one mile above sea level, it holds the official nickname "Mile-High City" and serves as the main gateway to the mountain parks, canyons and ski slopes of the American West.
The city proper is home to around 720,000 people, while the broader Front Range metropolitan area has a population of roughly three million. Denver was founded in 1858 as a gold-rush camp and grew rapidly into a commercial and railroad hub. Today it is a dynamic centre with a diverse economy spanning aerospace, energy, finance, telecommunications and a fast-growing tech sector. The climate is sharply continental and sunny almost year-round: dry, hot summers and snowy but often bright winters. The thin air at altitude means newcomers should drink plenty of water in the first few days and take it easy during physical exertion.
Colorado was among the first US states to legalise recreational cannabis, which became legal in 2014, so licensed dispensaries are common throughout the city.
Closer to downtown, the RiNo (River North) neighbourhood is worth exploring for its street murals and breweries, as are the Botanic Gardens and the Museum of Nature and Science beside City Park.
Denver's food scene blends modern American and Southwestern traditions: spicy green chili sauce, hearty burgers, Colorado beef steaks and, of course, craft beer — the city is regarded as one of the country's brewing capitals. Lunch at a café runs about $18–25, dinner at a restaurant $40–80, and a pint of craft beer $7–9. A light-rail RTD ride costs $3–6, and a taxi or Uber across downtown $12–20. Prices are as of 2026.
Denver International Airport (DEN) is one of the busiest in the United States, instantly recognisable by the white tent-like peaks of its terminal. The RTD light-rail A Line connects it to downtown, reaching Union Station in about 40 minutes. The wider RTD network includes commuter trains and tram lines, but beyond the centre a car is more practical. For trips into the mountains and national parks, renting a car is effectively a necessity.
Denver combines urban comfort with immediate access to wilderness, making it an excellent base for exploring the Rocky Mountains at any time of year.
