Flying to Denver
Denver is the gateway to the Rockies—skiing, hiking, and a growing city scene. Denver International is one of the busiest airports in the country, so you’ll find plenty of options and often good prices.
Airports
Denver International (DEN) is the main airport, about 25 miles northeast of downtown. It’s a major hub with strong domestic coverage and a growing number of international flights. The train connects the airport to downtown. Use the search form above to compare fares; competition is strong, so flexible dates usually help.
Timing
Peak times are ski season (December–March) and summer. For better value, look at January–February (non-holiday) or April–May. Tuesday and Wednesday are typically cheaper than weekends.
Denver’s altitude can affect some travelers. If you're heading straight to the mountains, consider an extra night in the city to adjust—and book your flight with that in mind.
