Montezuma Castle National Monument is actually two different sites. Montezuma Castle contains some of the best-preserved cliff dwellings in the United States. The second location, Montezuma Well, is located 7 miles northeast of Montezuma Castle and features a large natural limestone sink, which fills with water from an underground spring. Montezuma Well was used for a network of prehistoric irrigation canals. The castle is also headquarters for nearby Tuzigoot National Monument.
At Montezuma Castle the upper ruin has twenty rooms high in an alcove in the cliff's wall and can only be reached by two narrow trails. The lower ruin is at the base of the cliff and has forty-five rooms. These rooms could only be reached by using a ladder.
