Stayed at site 201 at the Hildebrandt campground. Sites are smallish. Most sites have some shade, but little privacy in between. The scenery wasnt that great, mostly vine like trees you'd see in a flood plain. The water pump was out during our stay and needed to go to the station near the modern campground.
We were scheduled to stay for 3d/2n but plans changed due to weather from hurricane beryl. It started to rain in the first evening and we had a mini creek running through our site. With the amount of rain projected to be on its way we could only imagine it being completely flooded.
Mosquitoes were awful even before the rain. Vault toilets were well taken care of.
If you want quite or the sound of nature, this campground is not for you. You can hear road traffic and trains at all times, especially at night. The general store near the campground entrance is a nice convenience if you forgot something or need ice/fire wood.
It is wonderful though how close the Campground are to Lake Michigan/warren dunes, which is why we stayed.
