We camped here in a tent passing through on our way north. Only cost us $10. Pretty spot and only a couple other campers in the area that night so we had plenty of privacy. It does appear that it is closed in winter but there is a forest road just south that you could camp on for free I'm sure.

We stayed here on the Friday night of Labor day weekend 2019 in a tent on our way west. Nice area with plenty of places scattered out so you don't have to be close to others. Only one other person staying in the area that night. And completely free!!
