It's 15 per night, that includes entrance fee. I really enjoyed this campground. I wish the lake was up. Don't step to close to the waters edge. The mud is like quick sand. It will eat your shoes.
Whatever the fee is, should be posted on website. I believe is was $15ish a night. Very limited camping. I recommend going up early or getting a reservation online.
