I love this place. It sits at about 6,500 feet and has only 13 FCFS paved sites on a single, paved loop. Get there early because while there is a lot of daily turnover, it usually fills by noon. It is open year-around but not cleared of snow in winter. There is a 26 vehicle length limit. All sites are back-in if I recall correctly. Each site has a table, fire ring and tent pad. Gathering firewood is prohibited. Water is available from a spigot at the Visitors Center. There is a five gallon per campsite per day limit. Toilets are vaults and there are no showers or dump station. There is a trash facility. Site size varies widely. I got #12 which I think is the biggest and best in the place. Privacy also varies although its pretty good for most sites since they are spaced well apart. The vegetation is juniper and pinyon pine. It has standard quiet hours (10:00 PM to 6:00 AM) and generators are permitted during the day. The cost is $10 per night. The monument has received a dark sky designation and often has an astronomy program at night. It can get very hot at NBNM during the summer so spring and fall are good times to visit. I had clear skies and high temperatures of 80 during my three-day stay. Here's a shot of my campsite in Natural Bridges.
