There are some double track and plenty of singletrack here. I don't believe there are one way trails except for one spot that is clearly marked. From parking area, follow the fenceline back and hang to left. Once around the corner you can see where the singletrack starts. Trails are maked well but no maps are available as far as I know. I have ridden quite a few times and I am still finding new trails. For the most part trails are flat with log obstacles and a couple creek crossings. There are a couple hills but nothing serious. They are in the process of adding new trails too. Singletrack is well built and there is plenty to explore. This is a nice jewel right in the city limits of Eau Claire.
A pump track is incorporated into the trail system kinda neat but nothing I would go traveling for.
