Arches Travel Tips

Arches National Park is located in southeast Utah, about 25 miles south of I-70 and 5 miles north of Moab on U.S. 191. The park is about 235 miles southeast of Salt Lake City and about 360 miles southwest of Denver, Colorado.

Geography and geology

In Arches National Park, the fabulous geological oddities known as arches are thought to result from the movement of unstable strata deep beneath the earth’s crust, then subsequent erosion by wind and water along with the weakening effect of freezing and thawing cycles on delicate sandstone formations. Beneath the earth’s surface here lies a thick salt bed, the residue of a vast sea that covered the land hundreds of millions of years ago.

Geologic deposits as much as a mile deep built up over this thick bed of salt, and the sea gradually disappeared. The unstable salt layers buckled and shifted beneath the weight of the hardened upper layers, creating faults and domes on the surface. As the surface was eroded by wind and water, delicate fins, spires, and balanced rocks — and, of course, arches—of harder stone were exposed and sculpted. These formations were further acted upon by wind, water, and extremes of temperature, leaving us this incredible geological treasure. (That’s the reasonable theory, but if your kids think these arch formations were left by gigantic prehistoric space invaders playing in a big terrestrial sandbox, they just might be right.)

Climate and weather

The Arches National Park weather varies greatly with the seasons. Spring brings warm days, cool nights, and strong winds. Occasional rain storms commonly occur in spring. Daytime highs average 60 to 80 degrees F and lows average 30 to 50 degrees F during the spring and fall.

Summer begins in May as daily high temperatures climb toward 100 degrees. Expect hot days in summer, with highs sometimes reaching 110 degrees. The park’s high elevation (between 4,000 and 5,700 feet), however, keeps temperatures cooler than in Moab or along the Colorado River. Summer mornings can be cool and delightful at Arches.

Expect afternoon thunderstorms in August and September, sometimes with torrential rain that floods dry washes and cascades off cliffs. Autumn offers brilliant days with clear skies and warm temperatures. October is the wettest month with an inch of rain. Winter can be bitterly cold and snowy; almost 11 inches of snow falls in the average winter. But the weather can also be dry and warm, with daily highs in the 50s or even 60s. Still, Arches National Park weather can be a bit unpredictable so it’s a good idea to check the forecast right before you depart and bring clothing suitable for a variety of weather conditions if you plan to do a lot of hiking.
