Flagstaff Mountain

Standing about 1,000 feet below Green Mountain, Flagstaff Mountain still presents a formidable challenge for runners. Much closer to Boulder than Green, Flagstaff is popular with cyclists, hikers, and tourists as well as runners. Our route starts from Eben G. Fine Park, which sits just outside of downtown and has restroom facilities and water available. From here you will start your 1,500-foot ascent. When you reach the Panorama Point you will join the Flagstaff Trail, a twisting rocky trail, peppered with wooden stairs, weaving through forests strewn with large boulders. Be careful as the Flagstaff Trail crosses Flagstaff Road several times. Eventually you will make your final road crossing as you near the top. At the summit you will find the Sunrise Amphitheater, an outdoor stone amphitheater built in the 1930’s. There are a few different trails that skirt around the summit. We like the Boy Scout loop, which dips through Douglas fir forests and offers sweeping views of Boulder, especially the red roofs of The University of Colorado campus.
