The Linn Creek Recreational Trail is built on the dike that runs along Linn Creek and the Iowa River in Marshalltown. Parks along the way offer picnic areas, playing fields for team sports and the Marshalltown Family Aquatic Center. At Riverview Park, visitors can camp with modern restrooms, electricity, city water and access to the bike trail.
Unique natural attractions can also be found along this recreational trail. The Nicholson Ford Nature Area features views of river bottom timberland and marsh and OHV Park. Trail users can observe prairie grasses and wildflowers at the prairie area near the west end of the trail.
Future plans are to extend this trail to the Highway 30/330 Trail to Melbourne. Another one-mile extension is planned to Sand Lake.
