Awesome campground! We stayed here for 2 weeks in our 2021 Keystone Hideout 250BH. They don't have a ton of sites and they are reserve only. The weekdays are extremely quiet but the weekends get a little busy due to the seasonal sites.
The sites are electric/water and they do have a dump station very close by. The central pond and waterfall were awesome!
As far as amenities - the bathrooms/showers were very clean and well kept. They also had laundry services! Mowing day is on Thursdays!
The only negative with our stay (which the campground can't help) were the mosquitos, flies, and bees. So bring bug spray!!!
There are several things to do - hiking, biking, caves, Lake Michigan, etc.
The New Hope Cave is only open to tour 1 weekend of the month. It is usually the 3rd Saturday of the month but there were scheduling conflicts and it was open on the 2nd Saturday in August so we weren't able to tour. We were still able to visit the other caves and walk around and look at wildlife. If you go when it is raining you won't be able to go in many of the caves as they become flooded but it does make some really cool waterfalls! The Manitowoc Breakwater Lighthouse is on Lake Michigan about 30 minutes away from the campground but we definitely recommend going to see it! We would definitely stay here again!
