Camped here thru the 4th of July weekend. The staff kept noise and other stupidity tamped down. They say quiet time is all the time, and I love that.
Typical MI state park, sites are electric (30a and/or 50a) only.
No real beach, but there is a swimming area. Picked up Detroit TV stations easily, good for the rainy mornings we had.
With T-Mobile, Internet service was practically non-existent. Phone calls & texts worked. The camper across from us said it was the same for Verizon.
One section is mostly paved & ADA sites, the "upper" section is grassy and/or dirt. Both restroom/shower buildings were fine, I just wish they had posted times when they'll be closed for cleaning.
All in all, we'd have no problem returning here.
