We stayed here for 2 nights just this past weekend. It was easy to get to and very well maintained. Our site(site 60) was right on the lake and absolutely beautiful. The layout of the loop we were on was very well thought out and plenty of space between sites so you don't feel like you were right on top of your neighbors. The way the sites were oriented, you had a fantastic view of the lake.
One thing to really consider is proximity to Clemson. When we booked the site, it was one of only a handful available however while walking our dogs, we noticed over half of the sites were unoccupied. With the cancellation of college football, this is not surprising. Fall will be a busy time so if quiet is what you are after, I would be mindful of the Clemson home schedule.
The bath houses were very clean, however there is no soap for washing your hands so keep that in mind if you use the facilities. The dump station was also nice and easy to use. Three large dumpsters for taking trash when you empty your tanks.
Not all sites have a separate grill and fire pit which was the only downside. Ours did not, but the fire pit did have a grate you could put over a fire and cook.
