From St. Louis, take Hwy 21 south to Potosi (60 miles); then, take Hwy 8 west 16 miles to FR 2266 following it to the Berryman Campground or continue on FR 2266 to FR 2265 and turn left; then, turn right on Hwy. W to Brazil Creek Campground.
Great Primitive Campground, and well kept. Not much firewood to scrounge, but you could buy it on the corner of 8 & Berryman, or if you live in-state bring your own like we did. There were a couple of real sweet dogs running around, not sure if they were local or dumped, but it was a great place.
Free; Can be a nice peaceful campground, but sometimes people on offroad machines race up and down the main road which is 25 feet away from the campsites. Hiking trail in the woods, just trees, no creeks, not much else to do. No cell service.
