Several trails take you around the park and through the hills and woodlands that make up Fort Defiance. Equestrian use is allowed on three of the trails. During winter months the park is a popular place for snowmobiling and cross country skiing.
Fort Defiance State Park's 191 acres of rugged woodland provide a beautiful contrast to the gently rolling surrounding farmlands. The park's trails, picnic areas and scenic overlooks provide a great place to relax. Its lush cover of vegetation includes hawthorn, plum, locust and many species of the state tree - the oak. In the spring, the slopes are speckled with trillium, bloodroot, hepatica and violets. A small prairie with native grasses and flowers, including the endangered prairie bush clover, thrives on a secluded knoll.
