Ionia Recreation Area Professional Review and Guide
"Boulders dot the open fields that surround this narrow trail system. Consisting of two loops, the trails maximize a long, skinny space. Maintained by Dan’s Bike Shop in Ionia, the two loops run through a mostly open, stony area, with few of the dense trees that are so common on Michigan trails. Beginning on the easier Brown Loop, the route follows a buffed, twisting trail, then picks up the Yellow Loop and dips into the trees for the first time.
Pedaling up and down a ridge, riders encounter the most challenges of the ride, including tight tree passages, short and steep climbs, log jumps, and sand. Following the railroad tracks, the trail finally climbs the ridge for good and begins the return route. Completely in the open, the second half of the Yellow Loop passes large boulders on a straight, mostly open trail with gravel and loose stones. It is impossible to get lost on this easy-to-follow trail system. Tread: 7.9 miles of singletrack."
