We stayed 3 nights at site number 9 in the midst of the pandemic. Overall fairly quiet and private. One side of site 9 is a parking area. Our site had a wooded trail down to the flowage and onto the Mondeaux Esker Trail segment of the Ice Age Trail (“East” segment - most people use the dam as their definition). I had a hard time confirming before hand but yes the trail runs right through this campground. The Mondeaux Esker segment was challenging (muddy) but fun.
Our site was large though not real flat. We fit a car, suv and 17 ft boat.
One drawback was the water at the campground is shut off due to bad water tests (not due to covid). Plan ahead - there is a glacial spring within driving distance and other federal campgrounds that you might be able to get water from. Pit toilets were very clean and didn’t stink. No showers. stayed late August 2020
