Ste. Genevieve to St. Louis: Historic River Country

Ste. Genevieve itself is a National Historic Landmark District, with French colonial architecture and the Sainte Genevieve Museum. The drive along I-55 passes the Jefferson Barracks Bridge over the Mississippi. Near St. Louis, consider a detour to the Gateway Arch National Park, which is not UNESCO-listed but is iconic, and the City Museum for quirky fun. The region is home to Cahokia Mounds State Historic Site (UNESCO World Heritage Site), located just east of St. Louis in Collinsville, IL. This pre-Columbian city features Monk’s Mound, the largest earthwork in the Americas.

St. Louis to Chicago: Prairies and Industry

This stretch cuts through the agricultural heartland, with flat plains and grain silos. An off-route gem: the Abraham Lincoln Presidential Library and Museum in Springfield, IL (just 2 hours north of St. Louis via I-55). In Chicago, the route skirts the city; consider a stop at the Indiana Dunes National Park (UNESCO Global Geopark) for stunning Lake Michigan shorelines. The park has 15 miles of beach and towering dunes.

Chicago to Mackinaw City: Michigan’s Forested Spine

I-75 north traverses Michigan’s Lower Peninsula through dense forests and along the Saginaw Bay. The route passes near the Hartwick Pines State Park (old-growth forest) and the Tawas Point State Park for birding. A major off-route detour: Traverse City (2 hours west via M-72) offers cherry orchards and the scenic Old Mission Peninsula. For a UNESCO gem, consider a side trip to the Ojibwe Caves at Pictured Rocks National Lakeshore (4 hours from I-75), but that’s a longer detour.

Mackinaw City to Cheboygan: The Bridge and Beyond

The Mackinac Bridge connects the Lower and Upper Peninsulas; Cheboygan is on the south side. This area is known for the Straits of Mackinac, where Lakes Michigan and Huron meet. Don’t miss the Historic Mill Creek Discovery Park (a restored 18th-century sawmill) and the Cheboygan River Front. For hidden gems: the Les Cheneaux Islands (12 miles east) offer kayaking and vintage boat shows.
