I believe the paper we just got from them said $24 a night. I will have to get it out of the car to confirm that. But the prices I have start May 1st. You can also visit the website to reserve a site, they are booking fast several months ahead right now. They also have walk in sites so you don't have to reserve one.
Its been a few years since i went but if i remember correctly itwas $13 a night. You can call the office and find out though.
