The trip to Capilla Peak camp is not for the faint of heart. You'll be traveling on a one-lane gravel and dirt track to 9200 feet above MSL, but once you get there, it's worth the journey. On a weeknight in August I had the entire campground to myself.
A couple of the eight sites have wooden awnings which are great on windy days. There is also a pavilion for group gatherings. All of the sites have fire rings and picnic tables. There isn't a place to park a trailer in the camp itself, but there are spots at the top of the driveway. I wouldn't bring a trailer up here anyway.
Easy access to the Crest Trail and the hike to Osha Peak is an easy two miles. Past Osha Peak you enter a pretty nasty burn scar and the trail becomes harder to follow. Hardly any people but tons of deer to keep you company!
