How to Get to Boulder

Boulder is 50 miles northwest of the airport, and to get there, the best route is the toll road, E-470. You will see signs shortly after leaving the airport. Take E-470 North. This becomes the Northwest Parkway after crossing interstate 25. It ends at a junction with route 36, and continuing west on 36 from there takes you into Boulder. For more information on the Denver International Airport, call (303) 342-2000.
