Durhamtown is definitely primo to ride woods. There's a 21 mile tight woods loop that's fun. The guy invents new trail periodically.
The place is very kid friendly with a pee wee track and more dirt roads / easy trail than you can shake a stick at. The mx track is short, but ok to play on. I see lots of families so your kids can make friends, roost on 'em then go home ha.
He has lodging . . . next closest would be Greensboro GA on I-20 or Athens if you like college towns (UGA - gotta hate em).
He even rents bikes, atv's.
If you get totally bored (not likely) there's a USFS ORV area close by called Towns Creek ORV. Nice to change once in a while. Towns Creek is closed in winter.
Whatever you do, ride somewhere.
Best,
