Airport and Transportation

Denver International Airport (DIA) is 45 miles from NCAR, and there are several ways to arrive. The AB1 bus (westbound to NCAR) is the least expensive option, which we strongly encourage you to take. It leaves the airport every half hour (see schedule) and stops throughout Boulder. Google Maps, on your phone or computer, also has up-to-the-minute bus scheduling information.

Plan your transportation to and from Denver International Airport (DIA) with the Next Ride trip planning tool (click image for link).

If you need other options, you may consider booking an airport shuttle with:.

  • Super Shuttle is a great option.

  • People also use Lyft and Uber from the airport to Boulder. This can be expensive.

  • Weather: Be prepared for weather to change throughout the day. Pack optional layers and have rain gear on hand (especially if you’re planning on longer activities like hiking). 

    Elevation: Keep in mind that Boulder sits at 5,318 feet (1621 m). If you are coming from a lower elevation, please be aware that some people can experience altitude sickness, which causes headaches, fatigue and dizziness. Here is a helpful link if you are experiencing such symptoms. 

    Staying hydrated helps with these symptoms, especially if you drink extra water before your arrival.

  • If you are looking for places to dine or purchase amenities, there are several nearby restaurant options:

    Safeway: This full-service retail grocery chain offers grocery, bakery, cleaning and household essentials, beauty and personal care, and electronics.

    Pearl Street Mall: This shopping complex hosts a large variety of restaurants as well as awesome shopping.

  • Hiking: Boulder has 155 miles of hiking trails. Check out All Trails to find one that will best fit your needs.
