This 185-mile loop follows quiet dirt roads and two-tracks through woodlands and grasslands among 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 acts as a northern extension to the Coconino Loop.

Perfect for bikepackers looking to get off the beaten path while following dirt roads and two-tracks, the San Francisco Volcanic Field Loop meanders through northern Arizona’s San Francisco Volcanic Field. 800+ volcanoes that erupted over the past few million years dot the landscape – some are a few hundred feet tall, and some tower many thousands of feet above the surrounding countryside. From Flagstaff, the route heads west toward Bill Williams Mountain on dirt roads and jeep tracks, passing through sprawling parks and ponderosa pine forests.

Bikepacking Roots LogoRoute Development: The Craters and Cinder Cones Loop was created by Kurt Refsnider to bring more riders into one of his favorite Arizona landscapes, as well as to create a northern extension to the popular 250-mile Coconino Loop (developed by Scott Morris and Chad Brown) to create a longer and even more diverse bikepacking experience.

Beyond Williams, the route enters deserted, dry pinon-juniper woodlands and then high grasslands of the Babbitt Ranches. You’ll pass eerily dark, yawning cinder cones before climbing into the young, cindery landscape of Sunset Crater National Monument. Sunset Crater is the youngest volcano in the area, having erupted just 1,000 years ago. The tallest peaks in Arizona, the San Francisco Peaks, are the final feature you’ll experience, climbing high into aspen forests at over 9,000 feet and then descending a hugely scenic water pipeline service road that’s closed to motorized use back toward Flagstaff.

This is a stellar ~3-day route with numerous options for side exploration and minimal technical riding in countryside rarely visited. But water is scarce, so plan accordingly.

Difficulty: This route is rated 4 out of 10 with some physical difficulty due to regular rolling terrain with sustained climbing, possibly frequent and unrelenting at times. Technically speaking, the track has occasional obstacles and steep sections (e.g., maintained forest roads, mellow singletrack); suitable for beginner mountain bikers.

    Arizona never disappoints in the route creation department, huh?

  • Endless.

    Schweet!

    Looks like a fantastic route. How would this country be in September/October? Much snow? How cold at night? I can’t get out there until the fall. Thanks.

    As first timers, we did the first 110 miles in 2 days, and then bailed before going around the north side of Humphreys. Fantastic trip with lots of variety. We did not take chances with the water and did a drop near our 2nd night camping. There lots of tanks with water but certainly did not look appetizing (late Sept 2017). The elevation climbs were very challenging and our pace was only about 9 mph so we usually were just arriving at camp at sunset or later. GPS is essential, there are so many side roads in this area. Loved this trip though – excellent!

  • Great feedback… thanks!!

  • hey, sorry I missed this. Sept/Oct should be perfect… just watch for early snow around Doyle Peak.
