Explore 2.5 miles of scenic, hilly turf trails at Murphy-Hanrehan Park Reserve with a guided evening hike during Parktober. The route includes a broad prairie view and opportunities to observe autumn’s seasonal changes. Three Rivers Park District hosts this all-ages outing, which is free to attend. The group meets at the Horse Trail Entrance off Sunset Lake Road rather than the park’s main entrance. The hike is scheduled for Tuesday, October 27, from 5:30 to 6:30 p.m. Parktober is the parks’ month-long trail-mileage challenge.
