This review covers two topics: the campground itself (4 stars) and the reservation/check-in process (1 star - more on that later). The campground itself is quite a drive from the entrance but is very beautiful. Well-maintained but sires vary greatly. Some are narrow pull-throughs; some have beautiful views and generous back-in drives. Good privacy between most sites (but not between 2 and 3). Cell service is spotty (Verizon); sometimes you get two bars and sometimes no service. Bathrooms were generally clean but no garbage can, hooks or soap (hand sanitizer dispensers) and they were serviced regularly during our stay. Solar lights on the path to the amphitheater/bathrooms were helpful. Two hiking trailheads can be accessed directly from the campground. No water spigots but each bathroom had a dishwashing sink which was much appreciated. Now for the flawed administrative system! We had reservations made six months in advance for three nights. We arrived a little after 4pm to find both the admission station and visitor center closed. No problem as we proceeded directly to the campground. There was a sign saying it was full and each site had a reserved placard but with no identifying information. Each night we were there, multiple sites remained empty. There was no camp host or ranger on-site during our entire stay. The only employees we saw were maintenance. Even the visitor center was unaware there was no camp host. Firewood locked up and not able to purchase. Fortunately, everyone was well behaved but it could have been quite a different situation if there had been a problem. Arches is a beautiful park and we are glad we had a good stay but hopefully their system will be overhauled soon!
