Lake Michigan Recreation Area at 6000 West Forest Trail Road, Free Soil, Michigan.

Beautiful campground, relatively secluded from nearby towns. The two loops we stayed in had an onsite manager living in one of the campsites. Both were very friendly and worked with us to find a campsite when someone was still occupying our site. Wood and ice are for sale at their site for reasonable prices. Bathrooms in Orchid are flush toilet (one stall only) and several spigots per loop provide drinking water. No showers.
There was sufficient space between sites to provide privacy. On our two nights we had no issues with rowdy neighbors. Lots of families with small children.
The beach is a short walk from your site. Each night we heard a different owl. Never had problems with raccoons or the supposed bears nearby.
