Your traditional sightseeing in Indiana belongs in Indianapolis, which is flush with big museums, an inordinate quantity of giant monuments and memorials, and a very nice canal walk with paddleboats and public art.
Outside the cities, and outside of the seemingly endless farmland in the plains, are a host of parks and outdoor recreation areas worth visiting. Without a doubt, the one to see, if you must choose, is Indiana Dunes National Lakeshore and Indiana Dunes State Park. The dunes are enormous, the water crystal clear, the swampy forests beautiful, and the far-off industrial views intriguing.
