This popular 10.6-mile hike begins gently in aspen groves, then crescendos with a climb up Arizona's tallest peak.

While Humphreys is considered the easiest of the western high points—it's only 10 miles from the latte bars in downtown Flagstaff—the long-extinct volcano has a volatile personality. Snow is common; afternoon thunderstorms are notoriously violent; and fierce winds along the mile-long summit ridge have forced many a hiker to scramble up on all fours.

From the north end of the first parking lot for the Arizona Snowbowl off AZ 180, it's 3.5 miles up to the 11,800-foot saddle between Humphreys and Agassiz Peak, the second highest in Arizona. When the snow is deep, beware of the huge overhanging cornice as you trace the undulating ridge to the first of three false summits. From the real one, the north rim of the Grand Canyon is often visible, 80 miles away.
