A dozen or so free tent sites. Tables, fire rings, grills. Vault toilets. Campers under 20’ should be okay. Larger RVs should consider a spot back off seven springs road. Going too much further up the road isn’t a good idea for RVs.
Road in is pretty good. Some washboard. Most vehicles will make it. I’ve done it several times in a compact car.
Late fall to early spring is best.
Zero cell service.
