Navajo National Monument is a National Monument located within the northwest portion of the Navajo Nation territory in northern Arizona, which was established to preserve three well-preserved cliff dwellings of the Ancestral Puebloan People. The monument is high on the Shonto plateau, overlooking the Tsegi Canyon system, west of Kayenta, Arizona. It features a visitor center with a museum, two short self-guided mesa top trails, two small campgrounds, and a picnic area. Rangers guide visitors on free tours of the Keet Seel and Betatakin cliff dwellings. The Inscription House site, further west, has been closed to public access for many years.
