This 2,421 acre property is owned by the Ga DNR. It's mostly used for hunting. So be careful about hunting season. It's an old plantation that has been turned into a WMA. Lots of roads and offshoots to try. Map can be picked up at Info kiosk in parking area. This place does not say bikes are allowed, but it doesn't say they aren't either. But it is a public place. And so far we've not seen anybody to run us off.
Approximately 4 miles west of Thomasville on US HWY 84 going toward Grady County. The entrance on the left is marked by a sign at .9 miles beyond the Ochlocknee River bridge. You'll see an open gate.
