What a gem! Just a short drive from Atlanta, this is a gorgeous park with great hiking trails and a beautiful lake for boating and swimming. My only complaint is with the reservation system - while you can make a camping reservation, you cannot reserve a specific site. We were coming from Florida, meeting a family from Nashville so neither of us could be there at check-in time (I was told there was a long line at check-in to get the best spots early - likely the lakefront sites). By the time we got there in the evening, we were told there were just a few sites together and likely not together. We got incredibly lucky and were able to find two fabulous sites together (sites 75 and 79) on a loop with lots of room for the kids to roam and play. While a lot of the sites in the campground didn't look like they would even fit our tent (it's giant at 10x20 - we have four kids), these two sites were a wonderful site for our family set-up. We loved hiking the trails and spent hours swimming in the lake. Overall a great experience aside from the stress of trying to find sites.
