Never again
This isn't a place to hear nature sounds. In fact, you'll only ever hear your neighbors screaming and partying.
The music starts at about 10pm and goes to 3am -- from a multitude of different sites, all playing different music.
On night 1 of our stay, we toughed it out. On night 2, we gave up at 11pm and packed up our tent into the car when they added ATVs driving through the camping loops with music blasting and bright flashing LED lights.
