Jay Cooke State Park

Snapshot virtual tour

Welcome to the Jay Cooke State Park virtual tour! In this journey you'll get low at the St. Louis River gorge, see up high from Oldenburg Point, and get a look down the Willard Munger State Trail. We hope it prompts you to visit the park in person sometime soon.

Willard Munger State Trail

With more than 50 miles of recreation trails in the park, a visitor could explore the park for days without following the same trail twice. The Willard Munger State Trail runs through Jay Cooke State Park, providing a paved surface for biking, in-line skating, and walking. The 70-mile Hinckley - Duluth segment of the trail is now completely paved.

River Gorge

One of the first things you notice when hiking the trails are the unusual rock formations. Nowhere else in the state is this type of rock exposed in such a large area. The Thomson formation is made up of slate and greywacke. Long ago, underground movements caused this formation to bulge and break, tilting the rock at 45-degree angles. Glaciers then deposited thick layers of red clay on top of the formation which would later be washed away by the river to expose the bedrock underneath. Wherever the red clay topsoil has not been eroded, it is almost entirely covered with brush and dense forests.

The rock formations, flowing river, dense forest, and abundant wildlife makes Jay Cooke State Park one of the premier natural attractions throughout the entire Midwest.

River Inn

You are standing in front of the River Inn Interpretive Center. This building is where people attend naturalist programs, learn more about the park by viewing the interpretive exhibits, picnic and warm up. The building was constructed by the Civilian Conservation Corps from company 2711 between 1939 and 1942. Most of the raw materials used to construct the buildings were from local sources. The local gabbro stone was quarried from a site in Gary, Minnesota, approximately 12 miles from the park. It is believed that the buildings supporting beams and rafters were built from local white pine trees. Originally the River Inn was constructed with a kitchen, dining room, enclosed picnic shelter, and restrooms. In the early 1980s the kitchen and dining room area were converted into exhibits and naturalist offices today.

Swinging Bridge

Most famous of all the landmarks in the park is the Swinging Bridge. The bridge was designed by Oscar Newstrom and built by the Civilian Conservation Corps. The bridge is a 200-foot-long suspension bridge with a 126-foot span over the Saint Louis River, it is supported by four massive pylons consisting of reinforced concrete piers faced with native stone laid in a rustic design. The suspension cables are anchored in a solid rock ledge on the south side and in concrete anchorage on the north. Stone piers on either side of the bridge support walkways leading to the suspended section.

Swinging Bridge

Originally built in 1924, the Swinging Bridge has been replaced many times. The bridge visitors cross today is the fifth version that's been built. The newest bridge was rebuilt to reflect the Rustic Design architecture of the 1934 Civilian Conservation Corps bridge. The river below is swift and choppy.

Oldenburg Overlook

Oldenburg Point is located just down river from the main park headquarters and offers spectacular vistas of the Saint Louis River Valley. Here you can not only enjoy the view, but have your picnic lunch in the pavilion while you read the various memorial plaques and history of the park.

Once the leaves have changed colors in autumn, the same overlook showcases a yellow and gold version of the river valley.

Oldenburg Memorial

The Oldenburg Memorial, a large granite boulder on a base of basalt stone, is a tribute to the memory of Henry Oldenburg from the people of Carlton County. The plaque mounted to the boulder recognizes Oldenburg as one of the people who made Jay Cooke State Park possible.
