The monument itself encloses 860 acres near the geographic center of Arizona and the intersection of the Colorado Plateau and Basin and Range physiographic provinces.

The dwellings and the surrounding area were declared a U.S. National Monument on December 8, 1906 as a result of the American Antiquities Act, signed  earlier that year.
It is one of the four original sites designated National Monuments by President Theodore Roosevelt.
Montezuma Castle was added to the National Register of Historic Places on October 15, 1966.

It is an easy monument to visit, just a short distance off Interstate 17, at exit 289.
There is a ¹⁄₃ mile (0.54 km) paved trail starting at the visitor center that follows the base of the cliff containing the ruins.
Access to the interior of the ruins has not been allowed since 1951 due to concerns about visitor safety and damage to the dwelling.
About 400,000 tourists visit the site each year.
The park is open from 8am to 5pm every day of the year, except for Christmas Day.

The visitor center includes a museum about the Sinagua culture and the tools they used to build the dwellings.
The museum houses many artifacts, such as stone tools, metates used for grinding corn, bone needles, and ornaments of shell and gemstone, which prove that the Sinagua were fine artisans as well as prolific traders.
There is also a Park Store operated by Western National Parks Association.
