A challenging high alpine bike ride, the beginning of the trailhead is located at an altitude of 10,000 feet. Ride the Aspen Vista Trail to the top of Tesuque Peak (12,045 feet) – a strenuous and long climb, 6 miles up; it’s not for the faint of heart. The views, however, are spectacular and it’s a particularly beautiful ride in the autumn when the aspens are changing color.
