Fantastic Sites, stayed at Thunder Viewspectacular sunset. Primitive camp, pack it in, pack it outno water (9-2016)toilet is not worth entering.
Spring water is available on Marion entry trails, but will take some work to pool and filter. Idyllwild side is dry.
Primitive campground, very clean sites. Gorgeous place to stay overnight. Water creek is still running 0.5mile down from Little round valley (Marion trail) .
