This is my favorite Forest Service Campground. No fee, no potable water, well-maintained toilet. Easy access to The Trail of the Gargoyles, Herring Creek, and Herring Creek Reservoir Campground. It's at 7,400' elevation so the season is pretty short because of the snow.
From the Forest Service website:
"Herring Creek Campground situated in a mixed conifer forest near Herring Creek. It is located on Forest Road 4N12; turn right onto Herring Creek Road (4N12) off of Highway 108, about 3 miles from the Summit Ranger Station. The campground is approximately 9 miles from the Summit Ranger Station. There are 7 sites; each site has a table and a fire ring. The main road and parking pads are dirt-surfaced. Potable water is not available. Toilets are vault."
