Throughout the 11,000 acres, surrounding Brookville Lake there are over 40 miles of hiking trails ranging from “easy” to “rugged”. A 24-mile loop, created by combining trails, is referred to as the Adena Trace Trail, which was created and designed with the assistance of the Hoosier Hiking Council (HHC), using some existing pioneer roads and deer paths as a base in some areas. The HHC and its volunteers continue to maintain the trails.
