    Low-Contact Travel at Denver International Airport

    DIA has launched Verifly, which reduces your contact with others at the airport and offers reservations for a dedicated TSA screening lane and a limited-capacity train car to the concourse. 

    Directions from DIA

    Exit DIA on Peña Boulevard. Continue until you reach I-70 west. Take I-70 west and keep right at the fork to continue onto I-270 (following signs for Fort Collins/Boulder). Continue on I-270 north, which will become U.S. Hwy 36 west and will take you straight into Boulder.


    Take the toll road exit, E-470 north from Peña Boulevard to the Northwest Parkway towards Broomfield. Take the exit for Hwy 36 and continue west on Hwy. 36 into Boulder. Please be aware this route has tolls, but can save time at peak travel hours.

    Local and Regional Airports

    Boulder Municipal Airport is a small hub serving business, private, recreational and emergency aviation services to the City of Boulder and surrounding communities.

    Rocky Mountain Metropolitan Airport is another smaller, regional airport situated between Boulder and Denver, just off Hwy. 36.
