If you have a short amount of time available for this park, this is your guide to 4 fun hours in Indiana Dunes National Park! We stopped on our way from the very interesting (still under development) Pullman National Historic Site to Cuyahoga Valley National Park (see our post here!) and had just 4 hours to spend and wanted to use it wisely! We left with mixed feelings about the Park, but if you are coming from Chicago you can catch the train and be here fairly quickly without driving!
