Trail is mostly all singletrack. Some of it winds along the creek. Not overly technical.
Coming North on Business 53 through Eau Claire, make a right on Spooner Ave (gas station on corner). Head about a half mile and the park will be on the right. If you went over the Otter Creek bridge, you went too far.
