Grand Marais to Saginaw: Lake Superior to Lake Huron Road Trip

The route from Grand Marais, MN to Saginaw, MI traverses the southern shore of Lake Superior and the Upper Peninsula of Michigan, ending in the Saginaw Valley. The drive spans approximately 600 miles, taking 9-10 hours without stops, but the geologically distinct shoreline and dense forest cover make it a journey worth savoring.

This route follows US-61 along Lake Superior, then crosses into Wisconsin on WI-13, and later US-2 through Michigan's Upper Peninsula, eventually linking to I-75 south. The most notable geological feature is the transition from the ancient basalt cliffs of the North Shore to the sedimentary sandstone of the Pictured Rocks, visible near Munising, MI.

The majority of the route is on two-lane highways with moderate traffic, except near major cities like Duluth and Saginaw. Fuel stations are sparse in the Upper Peninsula, with towns like Munising and Escanaba offering the last reliable stops before long stretches. As of 2025, gas prices in Michigan average $3.20 per gallon, and you'll need about 40 gallons for the round trip.

• The maximum speed on US-2 is 60 mph, but sections through the Hiawatha National Forest may drop to 55 mph.
• Cell service is patchy in the UP; download offline maps.
• Road conditions are generally good year-round, but winter (Nov-Apr) brings snow and icy patches; check forecasts.

The route passes near the only UNESCO World Heritage Site in the region: the Kluane/Wrangell-St. Elias complex is far away in Alaska, so no UNESCO sites on this drive, but the Pictured Rocks National Lakeshore is a National Lakeshore, offering similar protection. You'll also cross the Mackinac Bridge, a 5-mile suspension bridge connecting the Upper and Lower Peninsulas, with a $4.00 toll for cars.

Road quality is generally high, but watch for deer and moose, especially at dawn and dusk; collisions are common. Keep a safe distance from logging trucks that frequent the area.

For families, the Great Lakes Shipwreck Museum at Whitefish Point is educational and engaging, with an actual shipwreck bell on display. The Soo Locks in Sault Ste. Marie offer a free viewing platform where ships pass between lakes, fascinating for kids.

Pets are welcome at many outdoor attractions, but note that the Pictured Rocks boat tour does not allow pets. Plan for rest breaks every two hours; the rest areas on I-75 near St. Ignace have picnic tables and restrooms.

To avoid fatigue, take a detour to Tahquamenon Falls State Park, home to the Upper Falls, which are 50 feet high and 200 feet wide. This off-route spot adds only 30 minutes but provides a rejuvenating walk. The park charges a $12 daily vehicle permit.

Leaving Grand Marais, you'll drive along the Sawtooth Bluffs, dramatic rock formations carved by glacial meltwater. At Tettegouche State Park, the Baptism River drops 60 feet, a known photography spot. Further south, the deep woods give way to the farmland of Wisconsin, but the real highlight is the Pictured Rocks, colored by mineral stains.

In Munising, take a boat tour to see the cliffs up close; tours run from May to October, costing around $40 per adult. The town's local shops sell handcrafted items like birch bark baskets, but avoid buying any made from endangered species.

The Upper Peninsula is known for its pasties, a meat pie brought by Cornish miners. Stop in Ishpeming's historic downtown for a genuine pasty at a local diner. For a taste of local culture, visit the Marquette Maritime Museum, which tells the story of Great Lakes shipwrecks.
