Milwaukee [1] sits on the deepest harbor on the western edge of Lake Michigan. For miles, the city rolls like a sideways wave along the lake. You can drive the entire lakefront on WI 32 or bike most of it on separate county park bike paths. You pass nine beaches along the way.
South of the Milwaukee Art Museum and the Discovery World at Pier Wisconsin [2] is one of Wisconsin’s newest state parks, Lakeshore State Park, a nearly 20-acre parcel of land adjacent to the Summerfest grounds with beaches, fishing, and trails linking it to the entire rest of the state.
