Yes, it can get packed but be prepared to go early enough to find a good spot. I prefer camp sites 7 through 10, even the very first site when you first come in since they are right near the river. If you really want to experience the haunt of the campground I prefer the campsites in the back 11 through 16.
I have not experienced the haunts until I camped at spot 15, this past Labor Day weekend on Friday night August 30, 2024. I went to bed and about 12 am I heard a voice say Hello to me. Then the last night my friend and I were by the fire we did not have any more neighbors as they left that Sunday, we had our trash bag hanging from my friends canopy there was no wind and that trash bag was swaying back and forth rapidly. Was definitely an experience.
The hikes are the best especially if you have time to go to the lake which you want to get an early start, just follow the trail in the back past the reservation spot to get to the trail and follow up get to the fork in the trail and hang a left to the lake. I love the camp site always clean restrooms and fun experience for the paranormal.
