Overview
There are two access points to Rock Run: from Black Road and the Paul V. Nichols Access. Rock Run Preserve protects a diversity of habitats, including forest, prairie, wetland and a portion of Rock Run.
Wildlife found at the preserve includes the snapping turtle, Chicago garter snake and more than 100 bird species.
The preserve is also home to more than 500 plant species, including the violet, buttercup, mint, and aster.
There are several short loops on the trail system through the preserve. Both access points to Rock Run provide access to the 11.24-mile, paved Rock Run Greenway Trail. The Rock Run Greenway Trail connects to the Illinois Department of Natural Resources’ crushed limestone I&M Canal State Trail and the 4.36-mile, paved Joliet Junction Trail to provide a 16-mile, mostly paved loop trail.
