Route Details

Perfect for bikepackers looking to get off the beaten path while following dirt roads and two-tracks, the loop meanders through 800+ extinct volcanoes of all sizes, from small cinder cones to the towering San Francisco Peaks in northern Arizona.

Optional side trips include fire lookouts, cinder cone summits, and Lava River Cave. This loop also serves as a northern extension to the popular Coconino Loop to create a longer, incredible experience.

From Flagstaff the route passes through sprawling parks and ponderosa pine forests, to dry pinon-juniper woodlands and then high grasslands and finally into the high aspen forests of the San Francisco Peaks, before descending a hugely scenic non-motorized service road back to Flagstaff.
