Purchased in 1924, the preserve is located on the north bank of the Rock River and bisected by Dry Run Creek. The preserve was once a camping area of Stephen Mack, the county's first European settler, and Hononegah, his Native American wife. Upon entering the preserve, campers will enjoy the drive over the Rainbow Bridge and up into the cool maple grove. The Winnebago Indian Campground has campsites interspersed in a mature stand of white oaks and hickories. A launch for fishing boat access to the Rock River is available. The campground is located 2 miles from antique shopping & public pool in downtown Rockton and the Macktown Golf Course. Grocery shopping nearby. Host on duty in campground May-October. There are 60 sites (5-50 amp and 42-30 amp), dump station, horseshoe pits, & playground.
