Montezuma Castle National Monument
Tucked into an alcove about 90 feet up a limestone cliff, this 20-room Sinagua dwelling is viewed from below. Established in 1906, the monument also includes Montezuma Well, a separate unit that once supplied the Sinagua with water.
Agua Fria National Monument
About 40 miles north of Phoenix off I-17, this BLM monument protects mesa-top pueblo ruins, petroglyph panels, and the Agua Fria River canyon, with hiking, birding, and primitive camping; much of Bloody Basin Road needs high clearance.
Arizona State Capitol
Built from 1898 to 1901 and topped by a copper dome and a Winged Victory weathervane, Arizona's historic capitol now houses the Arizona Capitol Museum, including USS Arizona artifacts. Monuments and memorials fill Wesley Bolin Plaza outside.

Standing for more than 600 years, the Great House is the centerpiece of this preserved Ancestral Sonoran Desert People's farming community near Coolidge. Visitors can also see the adobe walls of Compound A and a visitor center museum.
Kartchner Caverns State Park
Discovered in 1974 in the Whetstone Mountains, this living limestone cave is seen on guided tours past formations like Kubla Khan, a 58-foot column, and a 21-foot soda straw; above ground, the park has trails and camping.
When you get to Agua Prieta
Right across the line from Douglas, Arizona, Agua Prieta grew up where the railroad from Douglas to the Nacozari mines met the border. Today it is a working border city built on trade, manufacturing, mining and ranching, and it serves as the gateway to the Sierra Alta circuit of small mountain towns in northeastern Sonora.

- Plaza de Armas Azueta: Locals call the main plaza the park of Agua Prieta's history and traditions, and it remains the setting for civic and community events. source
- Downtown churches: The Iglesia de Nuestra Señora de Guadalupe and the Iglesia del Sagrado Corazón are both listed among the city's visitor attractions. source
Douglas Historic District
Douglas grew up as a Phelps Dodge copper-smelting town, and this National Register district along G Avenue preserves its 1901-1935 commercial core, including the 1906 Gadsden Hotel and the terra-cotta-fronted Grand Theatre.
Gadsden Hotel
Opened in 1907 and rebuilt after a 1928 fire, this downtown Douglas hotel has a lobby with a white Italian marble staircase, gold-leafed marble columns, and a 42-foot stained-glass desert mural by Ralph Baker.

How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway mile markers, and "from the route" distances are straight-line, so the real detour depends on access roads. Stops are chosen from parks, natural sites, museums, historic sites and attractions close to the route (roughly 2 to 7 miles depending on the type, farther for World Heritage sites): at least one strong stop for each stretch of the drive, then the best-known places nearest the road, with no more than five of one type, up to nine in all. Places that are closed, private or not open to visitors are removed. Place and city descriptions are written by the Wayro team from official park, museum, tourism and government websites and other published sources. Safety levels and entry rules were checked against the U.S. Department of State on September 29, 2026. Conditions change, so check the linked sources before you travel.
