Fodor's Expert Review Montezuma Castle National Monument
The five-story, 20-room cliff dwelling at Montezuma Castle National Monument was named by explorers who believed it had been erected by the Aztecs. Southern Sinagua Native Americans actually built the roughly 600-year-old structure, which is one of the best-preserved prehistoric dwellings in North America—and one of the most accessible. An easy, paved trail (0.3 mile round-trip) leads to the dwelling and to the adjacent Castle A, a badly deteriorated six-story living space with about 45 rooms. No one is permitted to enter the site, but a viewing area is close by. From Interstate 17, take Exit 289 and follow signs to Montezuma Castle Road.
