Gilson Hills

The Gilson Hills mountain range in Illinois is a relatively small, gently-rolling upland area located in the southern part of the state. The hills are heavily forested with a mix of hardwood trees and provide a scenic, natural contrast to the surrounding flat farmland. The terrain is characterized by rounded peaks, shallow valleys, and intermittent streams. While not high in elevation, the Gilson Hills offer moderate relief and provide an accessible outdoor recreation destination for local residents.
