Denver Airports & Ground Transportation
One big question for travelers is which Denver airport to fly into. Here’s a quick guide to Denver’s airports and how to get to the city from each:
Denver International Airport (DEN)
Welcome to Denver International Airport, the largest airport in North America by land area! DIA is known for its iconic peaked roof, resembling the snow-capped Rocky Mountains. Inside, you'll find a wide array of shops, restaurants, and art installations to keep you entertained. Getting downtown is a breeze thanks to the frequent and affordable trains running directly from the airport to Denver Union Station. For travelers preferring other options, taxis, ride-sharing services, and rental cars are readily available. Tip: Be sure to check out the conspiracy theories surrounding the airport's art!
Tip: If you are planning to rent a car, make sure to book in advance, especially during peak seasons, to secure the best rates and availability.
Colorado Springs Airport (COS)
Just a hop, skip, and a jump south of Denver, the Colorado Springs Airport offers a convenient alternative for reaching the southern parts of the state. This smaller airport provides a more relaxed and less crowded travel experience compared to Denver International Airport. Though COS is further from Denver, it can be a great option if you're heading to destinations like Colorado Springs or Pueblo. Getting to Denver from COS is typically done via rental car or shuttle services. You might even spot Pikes Peak on your arrival!
Tip: Consider this airport if your final destination is closer to Colorado Springs to save time and avoid the Denver metro traffic.

Alright globetrotters! While Denver International Airport (DIA) is the main hub, consider flying into Colorado Springs Airport (COS) about 70 miles south.
