Washington County, Missouri

Nestled in the eastern part of the Show-Me State, we have Washington County. This scenic part of Missouri boasts rolling hills, crystal-clear streams, and dense forests that’ll make any nature lover weak in the knees.
It’s not just about pretty views, though. Washington County is home to some of the oldest rocks in North America. These ancient formations tell a story of the Earth’s geological history.
Potosi is the county seat that you can use as the perfect base for adventures. Speaking of adventures, the Mark Twain National Forest has endless opportunities for hiking, camping, and fishing. It covers most of the southwest region.
