A collection of once violent volcanoes dots the rugged high desert north of Flagstaff. Collectively called the San Francisco Peaks, or just ‘The Peaks’ by locals, today they sit dormant, offering a wilderness playground for adventurous visitors keen to hike, climb, bike or ski. The tallest is Humphrey’s Peak towering 12,633 feet, where hearty hikers can tackle a nine-mile, round-trip hike to its top. For wildlife spotting, lower elevation trails like Little Bear Trail wind through ponderosa pine, oak, and aspen forests, and the Lava River Cave offers great views and an exciting walk through a lava tube. The 44-mile Peaks Loop road is perfect for car-based sightseeing, while winter visitors can hit the slopes at Wing Mountain or the Snowbowl Ski Area.
