Jay Cooke State Park
Just 10 miles southwest of Duluth, Jay Cooke State Park draws visitors to one of Minnesota’s most dramatic natural features—the St. Louis River as it plunges through a deep rocky gorge, creating thundering rapids and cascades over ancient tilted slate bedrock.
The park’s most famous landmark is the 220-foot Swinging Bridge, a pedestrian suspension bridge built by the Civilian Conservation Corps in 1934. Cross it and you’ll be standing above the churning river, with breathtaking views of the gorge stretching in both directions.
With 50+ miles of hiking trails, cozy camper cabins, and the paved Willard Munger State Trail passing through, Jay Cooke consistently ranks among Minnesota’s top 10 most visited state parks—and it’s easy to see why.

St. Louis River Gorge
The St. Louis River is the lifeblood of Jay Cooke, plunging hundreds of feet through a dramatic rocky gorge. The tilted slate bedrock creates a spectacular scene—thundering rapids in spring, gentler cascades trickling around rock outcrops in summer.
Historic Grand Portage: This challenging terrain required Native Americans and early European traders to bypass the river on a 7-mile overland portage—one of the region’s most important historic routes.
⚠️ Safety Note: The river is NOT safe for swimming or boating within the park due to dangerous currents. Enjoy the views from the trails and bridge!
