Duluth to Des Moines Road Trip: Scenic Drive Through Minnesota and Iowa

This nearly 350-mile drive along Interstate 35 and US Highway 169 connects Lake Superior's rugged North Shore to Iowa's rolling plains. The route passes through remnants of the Laurentide Ice Sheet, visible in Minnesota's terminal moraines and glacial lakes.

Did you know that the segment from Duluth to Minneapolis roughly follows the old Mesabi Iron Range railroad bed? The highway was built atop former rail lines used to transport iron ore. This history is still visible in the steep grades and occasional rail sidings you'll pass.

Natural Landscapes & Attractions: From Duluth, you'll drive through the Superior National Forest region, with views of Lake Superior until about Cloquet. As you head south, the landscape transitions to the St. Croix River Valley, with steep bluffs and hardwood forests. Near the Iowa border, you'll encounter the prairie pothole region, a critical waterfowl habitat.

• Jay Cooke State Park (south of Duluth) – swinging bridge and rock formations.
• St. Croix National Scenic Riverway – hiking and canoeing.
• Pipestone National Monument (off-route but worth a detour) – Native American quarry site.

Fuel and Route Economics: Gas stations along I-35 are abundant near exits. For electric vehicles, charging stations are available in Duluth, Cloquet, Hinckley, Forest Lake, Minneapolis, Albert Lea, and Des Moines. The average fuel cost for a standard sedan is around $45–$55.

Climatic Conditions & Route Aesthetics: Spring (April–May) brings wildflowers and occasional rain. Summer (June–August) is warm with vibrant greenery. Autumn (September–October) offers spectacular fall colors in the St. Croix River Valley. Winter (November–March) can bring snow and ice, but the route is well-plowed.

Culinary Infrastructure: Food options range from iconic Midwestern diners to farm-to-table restaurants. Must-tries include: Taco John's (Iowa chain), Culver's (Wisconsin-based but common), and local cafes in Northfield, MN. In Des Moines, sample the city's growing food truck scene and the East Village restaurants.

Family and Child Suitability: The route is very family-friendly. Highlights include the Minnesota Children's Museum in downtown St. Paul, the Como Park Zoo & Conservatory in St. Paul, and the Iowa State Fairgrounds (off-season). Many rest stops have playgrounds.

Pet-Friendly Framework: Most chain hotels along the route (e.g., La Quinta, Best Western) allow pets. Pet relief areas exist at rest stops, but they are not common. Leashed pets are welcome on the St. Croix Riverway trails.

Hidden Off-Route Spots: About 30 miles west of US-169 lies the town of New Ulm, home to the Hermann Heights Monument and a vibrant German heritage. Another gem is the town of Lanesboro, nestled in a deep river valley—a perfect bike getaway.
