Lowell 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.
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.
Slide Rock State Park
Just north of Sedona in Oak Creek Canyon, an 80-foot natural rock chute worn slick by algae sends swimmers into the creek. The former Pendley homestead also keeps an apple orchard planted beginning in 1912.
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.
Sonoran Desert National Monument
Created in 2001, this BLM monument protects saguaro forests across the Maricopa, Sand Tank, and Table Top mountains. Traces of the Juan Bautista de Anza and Butterfield Overland trails cross it, and hikers, campers, and stargazers find three wilderness areas.
Organ Pipe Cactus National Monument
Near Ajo in the Sonoran Desert, this International Biosphere Reserve is the only place in the U.S. to see large stands of organ pipe cactus, with scenic drives, hiking trails, camping, and winter ranger programs.

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.
