As dewey02 mentioned, Indiana Dunes State Park doesn't really have anywhere to drive but into the campground area or beach parking lot. From the campground it's an easy walk to the beach area. This is a great park to consider a stop over. If you stayed here, you may need to book a site a few days before, or even more ahead if you stop here on a weekend. Also, the South Shore Line trains run all day to downtown Chicago and have a stop very close to the park.(maybe 1/2 mile away) It's an easy way to go into Chicago for the day. We stayed here many times and always enjoyed this park, often staying a day or 2 longer than planned. Also it is far enough away from the Interstate, it's
quiet at night.
