I made reservations online and it said you would be assigned a site on arrival. We were driving fro about 500 miles away so we knew we would be arriving late. I called the reservation number to check on the late arrival procedure and they informed me that if we arrived after 10pm that they close the gates and we forfeit our site.
This is not stated anywhere on the GA state parks reservation website nor in the confirmation email. I did find it on the Red Top Mountain specific site tucked into one of the general description paragraphs.
Anyway I called the information number and was able to find the Assistant Managers phone number and called them. They said that they have a gate but it's usually open. Arriving late was not an issue. He said to grab our packet of info from the registration booth and then choose any open site. He stressed to try to be courteous to other campers when arriving so late.
We arrived after midnight. Grabbed our packet then headed into the campground. Long story short... we couldn't find an open site. We drove around and around, which we really didn't want to because it was so late. In the dark it was hard to see the markings and some sites had long driveways so you couldn't see if it was taken or not. We would have to get out and walk into the site only to find it was taken. After 40 minutes of looking, and feeling like we were disturbing the whole campground we left and got a hotel for $67 about 10 minutes north of the campground.
The next morning we went back. I told the clerk/ranger what happened. She was pretty unsympathetic. She just said to go into the campground now and find a spot for our 2nd night of 2-night stay. She advised us to attach our name card to the site number post and leave some of our gear at the site so it was clear that the site was taken. We did that. We attached our reservation card to the post and left some of our camp chairs and a table at the site. We then headed into Atlanta for the day.
When we returned around 8:30pm we found that our site now had a huge camper parked in it and all of our stuff was gone. You got to be kidding me! This time we called the manager. Apparently, they do a sweep of the sites and mark whose names are on each site. He soon found our name on a totally different site. The people with the trailer had moved our reservation ticket and all our stuff to a different site and taken the site we had reserved. Very rude. By this time is was past 9pm and dark... I didn't want to argue anymore. So we just set up camp at the other site which was fine...just not as nice as the one that was swiped from us. The manager did end up crediting us the first night and 25% of the 2nd night for all the trouble.
Anyway... sorry for the rant. Needed to vent.
The park was nice. Well maintained. Wish we had more time to check out the lake. The cicadas were very loud! If you are a light sleeper bring some ear plugs. It was also very hot and humid but that's camping in July in Georgia.
