Is there any places to camp near boat rock near Atlanta

I’m Heading to Atlanta for a week and looking for any free camping spots for a motorhome?  Wanting to boulder in the boat rock area due to it just me and a number of problems to mess around on. Or camping near any of the couple climbing areas would work to I can always set up some top rope solos. 

Finding a Walmart is the only free option I can think of near Boat Rock. There is free camping at Mount Yonah, about an hour and a half away. Yonah has decent bouldering. You can also set up top rope solos in the range of 5.6 to 5.11 at the Lowers. You'll find parking for your motor home. The last tenth of a mile of the road is a bit rough, but I've taken a camper van up it no problem.

Well mount yonah it is. Hey thanks Andrew
