Upper Peninsula, Michigan

Five spots on the Portage — copper-country ruins, Jacobsville sandstone, a Lake Superior cliff where the rock is a billion years old, and one cove where bald eagles hunt at dawn.

Most Michigan visitors stop at Mackinac and go home. The UP is a different country — Lake Superior runs thirty degrees colder than Lake Michigan, the Canadian Shield geology predates most of North America, and the old copper-country mining infrastructure is preserved not because anyone built a museum but because people stopped needing to tear it down.

This guide is what the local field team reports back from summer weekends in Houghton and Calumet — the quiet between the Mackinac ferry and the Keweenaw cold fronts that come in off the lake without warning.
