We have stayed at stone mountain a number of times per year, matter a fact we will be there again over the Memorial Day holiday. Some of the red sites can be out of level, some more than others. We were at site 290 this past February (the only ones in the loop for the weekend) and it required stack of three 2"x6" planks to get the trailer level side to side. We have stayed on site 425 and it was level side to side but it was the first time I ever had the trailer tongue just about on the ground. We have had a couple of sites in the orange loop which the sites are pretty level all around there. Have a great time it's a lot of fun there.
