4 stars instead of 5 because so many people use open style, loud generators. No rule against it and campers respect quiet hours, but the noise is annoying. Otherwise 5 stars. Very clean, well taken care of by rangers and hosts. I stayed in the Mesquite Loop. Water available, no electric, large, mostly flat sites, each site has a covered picnic table and fire ring. The host even picks up your trash every day! Plenty of spots for primitive camping at the lake shore. Double dump station near park exit (room for 2 RVs at the same time). Ft Sumner is a nice town with decent prices on gas and diesel. Definitely a great campground and would recommend.
