Great Lakes Lighthouse Loop

Lake Michigan’s shore from Indiana to the Mackinac Bridge: lighthouses, dunes and a five-mile bridge.

A three-to-four-day trip up the east shore of Lake Michigan: the lighthouse in Michigan City, Indiana, the pier light in Grand Haven, the Dune Climb at Sleeping Bear, and the Mackinac Bridge where Lake Michigan meets Lake Huron. About 650 miles round trip.

Piers can be dangerous in wind and waves: stay off them in rough weather.

Play safe: the driver never uses the app while driving. Passengers play, or pull over somewhere safe and legal. Check road, weather and opening hours before you go.
