Enjoy a 2.5 mile hike along the newly created perimeter trail at Rock River Heritage Park led by Carl Lange. Carl has spent many hours walking, marking, and designing the perimeter trail. The hike starts at Heritage Hall at 9 AM; wear comfy shoes and bring plenty of water. Please be aware the trail finish work is not completed. There are marked hazards on the trail. Some of the marked hazards may be covered by leaves or snow.
