WARNING ⚠: Please read the IMBA Responsible Riding Rules of the Trail prior to riding.
WARNING ⚠: Please read the safety warnings on the Minnesota Department of Natural Resources Cuyuna Country State Recreation Area Trail Map.

This mountain biking loop takes you throughout the entire Mahnomen Unit of singletrack trails for a complete “Big Side” (as locals call it) experience. The loop starts and finishes in the Cuyuna Country State Recreation Area (CCSRA) Miner’s Mountain Rally Center. A Minnesota State Park Permit is required to park a car or truck in this area.

The entrance to the Cuyuna Country State Recreation Area will be to your left after you drive past the last stop sign within the City of Ironton via HWY 30/Irene Avenue. The entrance to the Cuyuna Country State Recreation Area is super close to town, but it’s kind of easy to miss the entrance as well.

This 10+ mile loop will take you through the Mahnomen Unit where you’ll experience both flowy singletrack and gravity Flow Country singletrack including Sand Hog and Screamer. Depending on your mountain biking speed, this could be a couple of hours, or a full day experience.

The trails within this loop are all one-way, one-direction singletrack trail.
