One hidden gem in Southern Illinois is one of 6 preserves owned and maintained by GreenEarth Inc. See their website information below.

An established trail will guide you through three different areas of this forest preserve. The 1.0-mile trail is moderate in intensity. You may wander from the trail, but be respectful of nature, please.
Use caution along the route, this site can be difficult to find. Look for a Green Earth sign on the left side of Kennedy Road. A small parking lot is on top of the hill's crest.
Permission to hide this geocache was given by Executive Director, Stephanie Eichholz
