Walnut Woods State Park is a 260-acre nature reserve situated along the Raccoon River in West Des Moines, Iowa. It preserves one of the largest remaining natural stands of black walnut trees in the United States. The park features a designated campground with both electric and non-electric sites available for reservation. Its topography is characterized by river bottomland, which frequently experiences seasonal flooding during spring thaw. A network of multi-use trails winds through the forest, providing opportunities for hiking, cross-country skiing, and bird watching.
