Swan Creek Wilderness Area is part of Mark Twain National Forest south of Chadwick. It's hard to find on a maps app but I promise you it is there. It doesn't have quite the overwhelming views as the first 3 entries do; but this is one place you can really get out, stretch your legs, and make some mileage. Another great thing is that there is potable water so you don't have to carry so much; a nice feature for this part of Missouri which can run dry at times.
