One of the best-kept secrets of the Midwest is that you can go to the beach for a day trip, and it is almost like being in the Atlantic, Pacific or Caribbean. Where? Lake Michigan, and specifically, Indiana Dunes State Park and the adjoining Indiana Dunes National Seashore. It’s only 45 miles east of America’s Second City, Chicago, in Chesterton, Indiana. There, you can go camping, hiking, sunbathing, swimming, and all of it with views of the beach and of the shimmering waters of the Great Lake.
