Conservation Areas in Missouri are enjoyable if you're looking for lovely scenery, and can get by with few or no amenities. Rebel's Cove is no exception: https://nature.mdc.mo.gov/discover-nature/places/rebels-cove-ca. It is located in Putnam/Schuyler Counties in northeast Missouri along the Chariton River and borders southern Iowa. Camping is allowed in the parking area and the grassy areas next to the parking areas. A map of the 4,225 acre conservation area showing the parking/camping sites is found here: https://nature.mdc.mo.gov/sites/default/files/downloads/conservation-areas/7944map.pdf The only amenity, is a unisex toilet at site E. The best camping, in my opinion is at one of 5 sites: At site A, where there is a wonderful overlook for handicap access overlooking the Chariton River swampland, at site E where there is the bathroom, but also quite a bit of mowed grass areas, at site G, where there is an old iron bridge over the Chariton that has a wooden walkway over the river, at site B where there is a neat shelter where the superstructure is constructed out of old barn timbers and where there is a lovely view of the hillside, and at site I, which is right up next to the River. Quite a few people use kayaks on the river. The river is 20 miles or so downriver from Rathbun dam in Iowa, and outflows from the dam vary the amount of water in the Chariton. The Chariton is largely channelized, but not here, so you get a good idea of what the River used to look like.
