Wildcat Den State Park is one of the most unique in Iowa, combining natural beauty and solitude, preservation of historical structures, trails, camping and picnic areas for recreational use.
One of the focal points of the park is the Pine Creek Grist Mill located in the eastern part of the park on Pine Creek. The mill was built in 1848 by Benjamin Nye, one of Muscatine County's first settlers who also built the county's first store and post office in 1838. The Pine Creek Grist Mill is one of the finest examples of mid nineteenth century mills left in the country and is on the National Register of Historic Places. The Friends of Pine Creek Grist Mill and the Iowa Department of Natural Resources is working to restore the mill to its original condition. The "turn of the century" Melpine Schoolhouse is located near the mill and offers park visitors another glimpse of Iowa's past.
