I made reservations through the South Carolina State Parks fantastic website. My 17 year old cousin and I were on a roadtrip throught the Carolinas and had plans to raft the Chatooga. I made the reservations for 2 nights and we headed over from Asheville which was a very pretty drive. The park is in a very picturesque area and was a lot of fun to drive on the curvy roads around there.
When we arrived which was right after the closing time of the park store/office we passed a ranger locking up. I mentioned that we had just arrived and she stayed for a couple minutes to point out our spot on the map. THANK GOD she realized that I had mistakenly made reservations in the "primitive" area and she quickly realized that we were city slickers. She was kind enough to reopen the office and move our spots to a nice site near the restrooms. The cash register was closed down but she was kind enough to let us get some things IOU (we paid in the morning) for our cookout.
The campground was packed with tent campers and Rvers but our site was spacious (and most importantly close to the ladies room). The tree canopy is fantastic and you are always in shade. It was also very quiet at night.
The bathrooms were adequate. Certainly not as sparkling as KOAs but we brought shower shoes and it was a heck of a lot better than some of the parks I've stayed at in other states.
We didn't check out the lake and were only there for rafting but I would love to go back for several days. We drove into Seneca the second night to eat. There were a lot of activities going on at the park and we took a drive to where the cabins are and they looked very rustic and pretty.
