Don't use Google maps! From Menominee, go up 35 to 551, then you'll see signs for the campground.
Campground itself is basic - pit toilet with tp, trash cans, fire pit, sites with picnic table and space for a tent, some equestrian sites, some group sites. Most sites are next to the river. Wooded, secluded. No camp minder/host/ ranger, so stayed up all night listening to a group partying with loud music and vomiting. Other than that group, would have been lovely time in the woods. Everyone else in the campground was quiet. Lots of dead downed trees around for finding firewood. Horseflies were awful next to the water, so no swimming for me. $20/night.
