re: Tent camping in Chattahoochee National Forest, Georgia

Crowds are kind of a relative term. For the at. It is busy but no more than your camp site. But if you don't camp at this crossing and somewhere else on the road, you will only see a car pass every once in a while during the day. Probably some motorcycles and mountain bikers, but they stay on the road. You would be slightly off.

When I say water, you would still need a filter. Would a porta potty work?

You might check out tallulah falls area. Might be more stuff to do with kids. Lots of short hikes. Panther creek falls is right down the street. 3,5 in. But pretty cool.
