Mackinac Island to Hermann Road Trip: Hidden Gems & History

Mackinac Island, where motor vehicles are banned, sets an unusual starting point for a drive south. You’ll need to take a ferry from the island to Mackinaw City (about 16 miles, 30 minutes). Once on the mainland, you’ll head southwest on I-75 for 50 miles to connect with US-10 near Grayling. This route unwinds through Michigan’s northern forests, then across Lake Michigan’s shoreline via US-31, before dipping into Indiana, Illinois, and finally Missouri’s wine region in Hermann.

The direct distance is roughly 700 miles, an estimated 11 hours of pure driving time without stops. But this trip deserves at least three days to appreciate the best stops Mackinac Island, MI to Hermann, MO offers.

Stop at the Tunnel of Trees (M-119) for a 20-mile canopy of maple and birch that explodes in color during fall. Near Grand Rapids, the landscape shifts to agricultural plains—orchards and cornfields replace pines.

In Illinois, the flat expanses of I-55 are broken by the occasional historic town like Pontiac, home to the Route 66 Hall of Fame. The Mississippi River crossing at St. Louis is dramatic, with the Gateway Arch rising from the riverfront. Heading west into Missouri, the Missouri River Valley’s rolling hills and limestone bluffs herald Hermann’s wine country. The region is known for Norton and Cynthiana grapes, used in robust reds.

From Mackinaw City, the first leg is mostly interstate: I-75 sweeps south to Grayling, then US-127 branches off toward Lansing. For a more scenic drive, consider US-31 along the Lake Michigan shoreline from Petoskey to Muskegon—adds about an hour but passes through Sleeping Bear Dunes National Lakeshore. Fuel is plentiful along I-75 and US-31, but prices are higher in tourist towns like Mackinaw City. Expect $3.50–$4.00 per gallon in summer.

Beyond Chicago, I-55 is a straight shot to St. Louis, but construction zones near Bloomington-Normal can cause delays. After St. Louis, MO-100 west from Washington is a charming two-lane road winding along the Missouri River bluffs into Hermann. Road quality is good throughout, but be alert for deer in rural sections of Michigan and Missouri, especially at dusk.
