Join park staff to celebrate National Trails Day as we bike the twelve-mile paved trail along the shoreline of Lake Wilhelm. The John C. Oliver Multi-Purpose Loop Trail is a true gem in the park. Participants can use their own bike or borrow from the park. All participants are required to wear a properly fitted helmet while biking.
