Need Class A site closest to Roswell, Georgia

looks like not much there. Your best bet might be Twin Lakes RV Park in Cumming GA.

We usually stay at Twin Lakes when visiting our son and his family in that area. It's an OK park with gravel sites. Cash only, no credit cards. However, we're going to try Sawnee campground on Lake Lanier the next time we go there. It's a COE park, and they have good sites for class A motorhomes.

I agree twin lakes in Cumming decent park be aware no amenities (bathhouse, laundry, etc..) but they are full hook up and they are right off highway 400/19 about 20-25 minutes from Roswell the COE parks are not full hookup and twin lakes also take checks.

OK. Looks like Twin Lakes is where we'll stay. Thanks!
