Offers picnic tables and over 9 miles of hiking and equestrian trails, which connect with Oak Ridge to the south. It offers relatively undeveloped natural areas as well as prairie restoration areas. It has a spring drinking water, at the parking area, but after that, your on your own. Outhouse bathrooms. Bring plenty of repellent.
