First come first serve, many sites (about 10-15?) $10.
Really love the site. It's gorgeous, well maintained with many amenities, and like the almost city like planning of the campsite. Docked a point because there's SO MANY WASPS even in October, and the trip to the parking lot to your site is around 30 seconds per way.
Btw, there aren't many camp sites near here, so plan ahead.
