Rock Cut State Park
With over 3,000 acres of rolling plains and two lakes, Rock Cut State Park is a hiker's paradise. It's also home to some of the best mountain biking in northeastern Illinois, offering 10 miles of dirt and sand terrain, doubletrack and singletrack trails. One of the loops is 4.25-miles, the Main Trail, which runs around Pierce Lake. Another loop snakes around the northeast corner of the park and leads through dense trees and hills.
