We stayed on one of the group sites, G6 on the Tour De Pepin weekend. The campground was very full that weekend but the group sites are spacious and well spaced out, (if you can I would recommend G4 or G5 right on the lake for group sites) you definitely don't feel like you are on top of each other or another group. Near the group sites there is also a set of vault toilets.
The campground is very green and luscious, full of beautiful trees, plants and wildlife, we heard bullfrogs, owls, woodpeckers and more (there are also train tracks near by so a couple trains too). This campground is a tent only campground with a couple cabins as well, which adds to it's secluded feel.
There is great lake access for swimming and a shower houses (bring your quarters though, showers cost 50 cents for 3 minutes). The only down side is that you cannot leave any cars near your campsite, you can drive in to drop off or pick up your gear but otherwise vehicles are parked in the main parking lot outside of the gate, which is not a big deal but from the group sites it is a trek to the lot and to the beach.
I would definitely stay here again, the lake is incredible.
