The state park is located within the boundaries of the Indiana Dunes National Park (formerly National Lakeshore), so don't get confused by this. There also is a national park campground, but it's closed in the winter.)

This state park has a nice layout because the sites seem to be staggered so that they don't back up to each other. Also, there is a good buffer space behind the sites and decent space between each site. 

All sites have 20- 30- and 50-amp service available, plus almost all are a combination of a concrete pad and asphalt apron. Note that just because they're paved doesn't mean all of them are level. Each site has a fire pit and it appeared they all have grill grates on them.

One nice touch is that some sites have wider asphalt aprons so if you have a longer rig, you can put your towing vehicle or your towed vehicle off to the side once your rig is in place. Also, the ADA sites are nicely laid out with larger concrete pads so that even the fire pits are in the concrete section for ease of access. 

Note that after Nov. 1, the water is shut off and bathrooms are shut down until spring, although there are vault toilets available. 

You will hear a pretty regular stream of train whistles at this campground, but they aren't so loud as to be disruptive. 

You can hike to the 1929 Dunes Pavilion and a large beach on Lake Michigan. The best hiking activity, however, and also easily accessible by walking from the campground, is the series of dune trails. The Nature Center, which sits between the campground and the trails, has some good visitor's information about the dunes, the flora and fauna, and the history of the area. 

Once you finish seeing what you want in the state park, there's still the entire national park to see. Plus, there's a multi-use trail that runs for 9 miles along the state park and into the national park. 

Cell service for Verizon was two bars but speeds seem to be good. Less signal and speed for Google Fi, but not terrible.
