Road Quality and Hazards

US-89 is well-maintained, but north of Flagstaff watch for elk and deer at dawn/dusk. The stretch through the Navajo Nation (US-160 & US-191) is two-lane with occasional potholes. In winter, I-17 near Flagstaff and US-89 near the Utah border may require chains or 4WD. Summers bring monsoon storms with sudden downpours and flash flood risks in washes.

For families, the drive offers plenty of kid-friendly stops. At the Wupatki National Monument (near Flagstaff), kids can run through pueblos. The Flagstaff Symphony Orchestra sometimes has family concerts. In Page, the Lake Powell Paddleboards and Kayaks rent gear for all ages.

Pet-Friendly Framework

Most national parks (Monument Valley, Wupatki) allow pets on paved trails. In Page, pet-friendly hotels include Holiday Inn Express. Rest stops along US-89 have shaded picnic areas. Carry extra water for your pet, as Arizona summer heat can be deadly. In winter, salt on roads can irritate paws; use paw wipes available at local gas stations.

Fatigue Management and Rest Zones

Plan rest stops every 2 hours. The Sunset Point rest area (mile 69 on I-17) offers stunning views of the Verde Valley. Further north, the Stigreaves Pass vista (mile 145) has picnic tables. After Page, the Glen Canyon Dam overlook has restrooms. The things to do between Phoenix, AZ and Monticello, UT include a short hike at the Paria Rimrocks (mile 320) to stretch legs.

Hidden Off-Route Spots

Just north of Mexican Hat, the Valley of the Gods offers a 17-mile unpaved loop through towering monoliths—even better than Monument Valley and free. Near Monticello, the Church Rock Trail (3 miles round trip) leads to a natural stone arch with few visitors.
