Red Rocks Amphitheatre is located in Red Rocks Park near Morrison, Colorado, 15 miles west of Denver.
From Downtown, take I-70 west to exit 259, turn left at the bottom of the Morrison exit ramp, cruise on downhill 1.5 miles to the Red Rocks Park entrance.
Coming from south Denver, take C-470 to the Morrison exit, turn west and follow the signs to the Park entrances. Here's a tip to avoid some traffic: you can also exit C-470 at Highway 285. Take it west to Highway 8 and then head north to the Amphitheatre!
