Boulder is located about 50 miles northwest of Denver International Airport (DIA) at an elevation of 5,430 feet above sea level.

From Denver International Airport to Boulder
Upon leaving the terminal or the rental car area, look for signs marked "Airport Exit" and "To I-70 & I-225 via Peña Blvd." Stay on Peña Blvd until it merges with I-70 westbound. Stay in the left or center lanes to avoid exiting onto I-225 and other cross streets, and continue westbound on I-70 for about 4 miles. Watch for the I-270 exit on the right, labeled "Westminster/Ft. Collins," that comes at about 14 miles from DIA. It is also labeled Exit 279, "US-36 Boulder." Take I-270 past Quebec, Vasquez, and York Streets, and past I-76 at 18 miles from DIA. Stay in the left lanes, until you pass under a "US-36 West/Boulder" sign at about 20 miles from DIA. (Do not exit to the right, towards Ft. Collins or Broadway.)

Or, alternatively,

Take the toll road exit, E-470 north from Peña Boulevard to the Northwest Parkway towards Broomfield connecting to US-36. Continue west on Hwy 36 toward Boulder.

Hwy 36 to Phase IV Engineering
Stay on US-36 into Boulder and exit at the Foothills Parkway exit staying in the left lane. Follow Foothills Parkway Northbound to Valmont Road (approx. 2 - 2.5 miles) and turn left on Valmont Road. At the first light (Wilderness Place) turn left and follow Wilderness around the Rockies Brewing Company. Phase IV Engineering is located across from the Southeast corner of the Brewery.
