The area around Elephant Mountain is beautiful and the mountain itself is a huge bluff sticking up out of the otherwise flat landscape.  The campsites are basic with a vault toilet in a little shack.  It was adequate for what I needed... just an overnight. But it's very hard to tell if a permit is needed.  Dyrt says Yes, and the info at the entrance says yes, but there's no indication how to get one.  I did not have a permit and nothing happened, but I was a bit paranoid. I'd say the landscape is the best part of this campsite.
