Walk ups only no reservation I came into this campground around 4pm on a Friday in July a little worried about finding a spot. When I arrived I was relieved to see more than half of the sites were open. Easy pay system $15 to camp clean bathroom and a shower!! Which you may need if you plan on hiking it gets pretty hot but we enjoyed our shaded picnic table. Nights were cool a must see the caves were magnificent great stop on the 93. Do it!
