So many areas here for your camping needs that come to mind now - you can even boondock along the road to Bonanza and Custer off Hwy 75, north of Sunbeam Dam, east of Stanley, and ATV along there, past Custer and into the hills beyond. This is ATV and RV country. Just move here and you'll probably find your new neighbors all camp and ATV.
The Warm Lake area is big for ATVing as is Horsethief Reservoir. We took our Jeep up to Stolle Meadows to scout out camping areas and there were big fifth wheels up there dispersed camping. What we found interesting is there was also a nice big CG with a nice vault toilet, and there was no camping fee. There was a big fire up in that area years back so it's a big open areas with burned remains but to me it's still beautiful.
