Maybe avoid Memorial Day weekend?
Camped here for Memorial Day weekend. It's a beautiful park and lots of families seem to enjoy it. This was a very busy weekend to camp here, and the campsites are all pretty close together without much in the way of barriers between campsites, particularly in the South and North Hill areas. We didn't realize this, and we ended up being in the middle of a bunch of people who like to play music and hang out with friends and family. If that's the vibe you're going for, this is the place for you. If you are looking for something more peaceful, I'd suggest finding somewhere else to camp.
