Walnut Woods State Park's boat ramp on the Raccoon River provides access for fishing and canoeing in a 260-acre wooded park featuring Iowa's largest natural stand of black walnut trees.

The ramp is located on the west end of the park and accommodates both motorized boats and canoes for float trips down the river. The park offers modern restrooms, a sanitary dump station, and nearby camping facilities with electric hookups for extended visits.
