A large campground with 33 sites, including group sites, this is a great wilderness campground, on a little used paved forestry road. It is open from Memorial Day through Labor day. We passed by in April and had the road to ourselves, but I imagine it's somewhat busier in the middle of the year. Full information for the campground, from the USDA website, is below.
