Ephraim to Munising Road Trip: Scenic Upper Peninsula Drive

When crossing from Wisconsin's Door Peninsula to Michigan's Upper Peninsula, you'll traverse the only stretch of US 2 that briefly enters Wisconsin north of the bay, connecting the ferry town of Ephraim to the Pictured Rocks gateway of Munising. This 180-mile route via WI 42, US 41, and M-28 typically takes 4.5 to 5 hours without stops, but the allure lies in the two Great Lakes you'll hug—Green Bay and Lake Michigan—and the subtle shift from limestone bluffs to sandstone cliffs.

Leaving Ephraim, you'll take WI 42 north to Sturgeon Bay, then follow WI 57 to US 41, crossing the Wisconsin-Michigan border near Menominee. The route is mostly two-lane highway with posted speeds of 55 mph; expect construction delays in summer near Escanaba.

• Fuel up in Sturgeon Bay (last cheap gas before the bridge) and again in Escanaba; prices run 10-15 cents higher in Munising.
• Cell service drops between Cedar River and Rapid River; download offline maps.
• No tolls on this entire route.

If you're wondering how long to drive Ephraim, WI to Munising, MI exactly, the 275-mile direct route via US 41 and M-28 takes about 5 hours non-stop, but we recommend the longer scenic route along the Lake Michigan shore for an extra hour—adds 40 miles but offers superior views.

The drive escorts you from the orchards of Door County to the dense hardwoods of the Hiawatha National Forest. Two UNESCO World Heritage Sites lie within a day's detour: the Frank Lloyd Wright buildings in Spring Green (south, 3 hours) and the Mackinac Island (east, 4 hours), but the immediate route passes near the Laughing Whitefish Falls, a 100-foot cascade just 20 minutes off M-28 near Au Train.

Local commerce thrives in small towns like Gladstone, where the Days River Inn serves whitefish livers, a regional delicacy. In Munising, the how to find the best stops and hidden gems between cities guide can lead you to the Muldoon's Pasties, a pasty shop that's been rolling since 1946.

Most of the route is rural highway with occasional deer crossings, especially at dawn and dusk. Shoulders are narrow in Wisconsin; in Michigan, wider shoulders appear after Rapid River. For families, the best stops between Ephraim and Munising include the Door County Maritime Museum in Sturgeon Bay (hands-on exhibits) and the Escanaba's Ludington Park with its splash pad. Pet-friendly rest areas exist at the Michigan Welcome Center near Menominee with leash-included grassy field.

To combat fatigue, plan rest breaks at the Rest Area at Mile Marker 100 on M-28, which has picnic tables and a dog run. If you're asking is it worth driving Ephraim, WI to Munising, MI, yes—the payoff is the Pictured Rocks boat tour, but the journey itself offers roadside berry stands and the Indian Lake State Park beach, a hidden gem for a swim.
