Hiking
The trails within Barnhart-Van Peenen Park are singletrack and more technical than the other trail systems in town. There are definitely some wider and smoother beginner trails (such as the access road trails), but as you branch off onto tighter trails, be prepared for rockier and rootier hiking with more hills.
