Painted Desert Inn

Petrified Forest National Park
Colorful badlands of the Painted Desert, grasslands, and vast deposits of petrified wood span more than 200 million years of geologic history here; visitors can hike the Blue Mesa Trail, see petroglyphs at Puerco Pueblo, and cross historic Route 66.
Homolovi State Park
Homolovi, Hopi for "Place of the Little Hills," preserves ancestral Hopi villages from the 1200s to the late 1300s near Winslow. The park has a visitor center and museum, trails through the sites, a campground and an observatory.
Walnut Canyon National Monument
Cliff dwellings built between 1125 and 1250 CE line this canyon near Flagstaff. The Island Trail descends 240 stairs past 25 of them, while the shorter Rim Trail offers wide views of the canyon and its dwellings.
Lowell Observatory
Percival Lowell founded this Mars Hill observatory in Flagstaff in 1894, and Clyde Tombaugh discovered Pluto here in 1930; today visitors can see the Pluto Discovery Dome and look through public telescopes at the Open Deck Observatory.
Oak Creek Canyon
Between Sedona and Flagstaff, State Route 89A follows this red-rock gorge for about 15 miles, climbing roughly 2,200 feet with hairpin turns and passing Midgley Bridge, Oak Creek Vista, and Slide Rock State Park.
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.
Yuma Desert
South of Yuma along the Mexican border, this low Sonoran Desert plain is a sweep of sand dunes and sandy soils, including the Yuma Dunes, where rare plants such as sandfood grow and flat-tailed horned lizards and fringe-toed lizards live.

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.
