Washington State Park
A great spot for a quick get away from St Louis. Beautiful park with lots to do not far from the campground. If you are tent camping you don't have to worry about generators from the RVs as there are two separate camping areas that share a really nice shower house, but have their own bathrooms as well. Be careful to not get a tent site in the middle, in the low area, as rain runoff will run down to the middle area. No tent pads, but plenty of grassy areas to pitch your tent. Activities in the park include swimming in the pool or the Big River, canoeing (rent at the Thunderbird Lodge), hiking, and petroglyphs.
