Great Campground
Pros: Free!! Close to Columbia but far enough away for a getaway. Easy to find from the road, even in the dark. Fire pits and picnic tables are there. Vault toilets and running water available. Hiking trailhead at the entrance of the campground. Camping spots are spaced out enough.
Cons: Can hear lawn-mowing and Gun shots from neighboring properties in the early morning. Still not the end of the world. Definitely fills up on the weekends.
I stayed at #3 and it was a very spacious private spot. If you have kids/dogs I recommend spot #4 it has a long strip of playroom for running around without disturbing other spaces. 2 week maximum stay.
