Stayed here at site D for two nights - the site was great, with gorgeous views of the Mississippi, tons of different birds coming by, and just enough room for our giant tent and a couple of hammocks. Even got a nice view of the milky way! The site is maybe 200 feet or so from the parking, and there are big plastic wheelbarrows you can use to haul your gear. The park had the perfect number of trails for us to tackle with our 5 and 10 year old, but not much else to do (which was fine with us). We did end up doing a short canoe trip on the Grant River which was also great. There's an agricultural museum across the way, but was closed due to covid. There were a lot of trains, but that never really bothered me - but it was noticeable if you're sensitive to that kind of thing.
