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.

  • Quiet, non-technical riding through pine forests and grasslands
  • 1,000-year-old cinder landscapes and lava flows in Sunset Crater National Monument
  • San Francisco Peaks’ Inner Basin and the Waterline Road traverse
  • Fire lookout side trip options on Red Mountain and O’Leary Peak

Updates affecting Craters and Cinder Cones (last updated 16 May 2023)

  • Waterline Road just north of Flagstaff on the east side of the San Francisco Peaks is CLOSED to the public for 2023 (USFS closure order and map can be seen here) due to damage from post-fire flooding. Schultz Pass Road east of Schultz Pass is closed to motorized vehicles for this summer, but it is open to non-motorized travel, so please use this detour. Expect sections to be washed out and quite rough due to flood damage.
  • New CO Bar Ranch free permit requirement: The northeastern part of the route crosses a checkerboard of State Trust and private lands of the CO Bar Ranch. Access to the ranchlands (for camping or crossing on 2-tracks) now requires a free permit available here; also see that page for ranch rules and requests.
  • SP Crater closure: On the northeast part of the route, the SP Crater area has recently been designated as the SP Crater Golden Eagle Complex and is closed to public recreation annually from January 1 to May 31. This closure includes the area 2 mile radius of SP Crater, so camping and hiking are prohibited during this time. More information about the Golden Eagle Complex can be found here.
  • The Craters and Cinder Cones Loop was developed by Kurt Refsnider to create a northern extension to the popular 250-mile Coconino Loop (developed by Scott Morris and Chad Brown) and to share with bikepackers one of Kurt’s favorite Arizona landscapes.
  • The route traverses the traditional lands of the Hohokam, Pueblo, Zuni, Hopi, Western Apache, Dine (Navajo) and Havasupai peoples.
