We stayed in site 1, which was lovely. A little less secluded, but most convenient. It's up on top of a dune, surrounded by trees, with so many birds! It is definitely walk-in, so I would bring a wagon if you can, or be prepared in some way to carry your gear. There is a picnic table at the site. We chose to eat dinner down at the beach (about a 5-10 minute walk), and had a gorgeous sunset with the Chicago skyline far in the distance. The rangers we consulted with beforehand told us mixed things, but the restrooms at the beach were open and had potable water. There is also a well-stocked Dollar General not far away where we bought water (before realizing there was water nearby). We were bike camping, and it all worked beautifully. We were a little anxious about not having a place to secure food overnight, but we had everything tidy and no critters got into it. If we had had a car, we would have left our food inside the car; we saw a raccoon not far from the site. Beware of ticks.
