I camped there 2 years in a row '99 and '00. There are no numbered spaces like at a park. You basically sign in and find an empty spot. I would discourage just showing up with a tent. The price of the space used to be based on the size of a tent. Last time I went I think it cost me $90 for the space and 4 day pass. And if you are camping, you had to buy the 4 day pass. Not sure what it is now.
