Proximity to the Ice Age National Scenic Trail earned Milwaukee a spot on National Geographic's list of top 15 cities for hiking in the United States.
The magazine's write up: "Eskers, kames, and potholes are a few of the trippy things you might see on Wisconsin’s 1,000-mile-long Ice Age Trail. (Translation: the elongated ridges, small marshes, and teardrop-shaped hills that the last continental ice shelf left behind.) And one section of it, in the northern unit of the Kettle Moraine State Forest, is located just 53 miles north of Milwaukee."
Hikers can find sections of the Ice Age Trail closer than that, in the Lapham Peak recreation area in the Town of Delafield.
