Canoeists and kayakers looking for quiet lakes and hikers, off-road bikers, and horseback riders looking for a variety of trails should consider a visit to Hartman Creek State Park, in the center of Wisconsin near Waupaca.
The single track trails were smooth and well-marked. There were quite a few people biking, however, and even though they're said to be two-way, you're going to have to be careful of a collision if someone is coming from the opposite direction.
Great trails. Could be done by anyone, many different routes. There's isn't one 8 mile loop like it may seem because of the description, but there is def 8 miles of trails you can navigate between. A lot of shade too! I was out on a sunny saturday afternoon and came across just one couple, which is always nice. Will be back.
