Duluth to Mackinaw City Road Trip: Scenic Lake Superior Drive

Driving from Duluth, MN to Mackinaw City, MI is a journey along the southern shore of Lake Superior, the largest freshwater lake by surface area in the world. The route via US-2 and I-75 spans about 340 miles, typically taking 7 hours without stops. But the real draw is the stunning Lake Superior coastline, Pictured Rocks National Lakeshore, and the Mackinac Bridge.

A little-known fact: the stretch of US-2 in Michigan's Upper Peninsula contains the longest undeveloped freshwater coastline in the United States. This road trip is best taken between May and October to avoid harsh winter conditions.

The primary route is US-2 East from Duluth through Wisconsin's Bayfield Peninsula and Michigan's Upper Peninsula, then I-75 South across the Mackinac Bridge to Mackinaw City. Key highways: US-53, US-2, MI-28, and I-75.

• Fuel stops: Every 30-50 miles; last cheap gas before Mackinac Island is in St. Ignace.
• Cell service: Sporadic between Ashland and Munising; download offline maps.
• Tolls: Mackinac Bridge $4.00 per car (southbound only).

Estimated driving time: 7 hours with no traffic; add 3-4 hours for stops. This drive is worth it for the solitude and scenery, especially at sunrise or sunset.
