We had 3 couples who spent the long weekend for 4th of July (2016) on two sites in the walk-in tent camping area. There are (non-flush) potties at the tent camping area, but if you're grossed out by those, it's a couple of minutes drive to the closest bath house. The bath house was very satisfactory and pretty clean, plus plenty of hot water. There's a (steep!) trail from the tent camping area down to the lake with some good places for swimming. It would probably be tough to walk a kayak down to the water from tent sites, though. We found the gravel tent pads well maintained and clean.
The location near Ellijay is great. We visited a couple of area wineries, and there's a fun mountain bike trail at Woodring Branch rec area (directly across the lake from Doll Mtn. Campground, but no direct route to get there, so it's about a 45 minute drive.)
I love traveling and thought this campground was very nice. All camping is fun if you make it so. Get out there and live.
Camped at Doll Mountain on Carters Lake again this past weekend. Perfect weather and a great trip. The lake is not developed and very quiet so perfect for kayaking.
Nice, quite and close to Atlanta. Many sites on the lake but the shoreline is steep.
