The Saint Louis River is a sight, especially from the historic truss bridge that crosses it on the William Munger Trail. You can feel the force of the water as it carves a deep gorge through the rocks, creating a dramatic contrast with the forested hills. The bridge is part of Jay Cooke State Park, where you can find plenty of hiking, biking, and camping. The park also features the Thomson Dam, a hint of Duluth’s industrial past.
