I have never used the MX or ATV trails in the Atlanta area, but the ORV Routes in the area will take you through some scenic woods, a couple of nice lakes to drown a few worms, and the opportunity to see some elk. Unfortunately a handful of clearcuts now dot the landscape too. There are a couple of sandy spots that can be interesting in 2wd with 40psi in your tires, but this is not a go-to destination for 4wd recreation. There are some nice areas to set up camp on or close by some of the trails if you are looking to avoid campgrounds too.
