Driving from St. George to Flagstaff

Route: I-15 S → I-40 E through Kingman

Head south on I-15 through the Virgin River Gorge into Nevada, then take US-93 South at the I-15/US-93 junction near Las Vegas. Continue south through Kingman, Arizona, then head east on I-40 through the high desert. The landscape transitions from Mojave Desert scrub to ponderosa pine forests as you climb to Flagstaff's 7,000-foot elevation.

About Flagstaff

Flagstaff is one of the most appealing mountain towns in the American West — a place where historic Route 66 runs through a walkable downtown filled with independent breweries, restaurants, and shops, all surrounded by the largest contiguous ponderosa pine forest in the world. Home to Northern Arizona University and the Lowell Observatory (where Pluto was discovered in 1930), Flagstaff has the intellectual energy of a college town combined with the outdoor recreation opportunities of a mountain resort. For St. George residents seeking a cool escape from summer heat, Flagstaff's 7,000-foot elevation delivers temperatures 20-30 degrees cooler than the desert floor.

The drive from St. George takes about 5.5 hours via I-15 South and I-40 East through Kingman, but the destination more than justifies the journey. Flagstaff serves as the primary gateway to the Grand Canyon South Rim, which is just 80 miles south via US-180 and AZ-64. Unlike the North Rim accessible from Southern Utah, the South Rim stays open year-round and offers the most iconic viewpoints, lodges, and visitor services. Many travelers combine a Flagstaff stay with a Grand Canyon South Rim day trip for a memorable long weekend.

Beyond the Grand Canyon connection, Flagstaff stands on its own merits. Humphreys Peak rises to 12,633 feet — Arizona's highest point — offering challenging summit hikes in summer and skiing at Arizona Snowbowl in winter. The downtown brewery scene rivals cities many times Flagstaff's size, with multiple craft breweries pouring within walking distance. Walnut Canyon National Monument, Sunset Crater Volcano, and Wupatki National Monument are all within 30 minutes. The Museum of Northern Arizona provides deep context on the region's geology, archaeology, and Native American heritage. Whether you come for the Grand Canyon, the mountain trails, the craft beer, or simply to escape the heat, Flagstaff rewards the drive.

Weather & Climate

Winters are cold (30-45°F days, 10-20°F nights) with over 100 inches of annual snowfall. Spring and fall are mild but variable (45-70°F). The elevation means UV exposure is intense — wear sunscreen year-round.
