Quick Fact
Yes, Denver is served by a major international airport. You'll find Denver International Airport (DEN) about 25 miles northeast of downtown. Honestly, it's Colorado's only international airport, and as of 2026, it's still one of the planet's busiest hubs. Its coordinates are 39.8617° N, 104.6731° W.
Geographic Context
Think of DEN as more than just Denver's airport—it's the main aerial gateway for the entire Rocky Mountain region. Sitting out on the high plains east of the city gives it a pretty crucial spot. For a lot of travelers, it's simply the best way to get to destinations across Colorado, Wyoming, or Montana. It funnels millions of people every year into the American West, which explains its massive scale. That size is a direct response to its job: connecting flights across a huge, sparsely populated area.

Interesting Background
They opened this place back in 1995, replacing the old Stapleton International Airport. It was a seriously ambitious project built for future growth—that's why it sprawls over 33,000 acres (making it the largest airport in North America by land). You can't miss the iconic roof, with its fabric peaks designed to look like the Rockies. And, of course, it's spawned all sorts of conspiracy theories thanks to its sheer size and some unique art. After a 75-day halt to international flights in 2020, its recovery just shows how resilient and critical this hub really is.
Practical Information
If you're going to Colorado, DEN is almost always your best bet. Getting around is easy: there's extensive ground transport, including the University of Colorado A-Line train. That'll get you to downtown Denver's Union Station in about 37 minutes. The layout is big, but it's logical—a central terminal connected by an underground train to three concourses. Because it's a major hub for several airlines, you'll typically find good airfare deals. Heading to Boulder (42 miles away) or Aurora (20 miles)? Renting a car or catching a shuttle is straightforward. Just a heads up: travel cost estimates from the fact source use pre-2020 data, so you'll want to check 2026 prices.
