More than 1.5 million visitors come to Arches annually, drawn by the red rock landscape and its wind- and water-carved rock formations. The park is named for the 2,000-plus sandstone arches that frame horizons, cast precious shade, and are in a perpetual state of gradual transformation, the result of constant erosion.

Fancifully named attractions like Three Penguins, Queen Nefertiti, and Tower of Babel stir curiosity, beckoning visitors to stop and marvel. Immerse yourself in this spectacular landscape, but don’t lose yourself entirely—summer temperatures frequently exceed 100°F, and water is hard to come by inside the park boundaries.

It's easy to spot some of the arches from your car, but take the time to step outside and walk beneath the spans and giant walls of orange rock. This gives you a much better idea of their proportion. You may feel as writer Edward Abbey did when he awoke on his first day as a park ranger in Arches: that you're walking in the most beautiful place on Earth.

It's especially worthwhile to visit as the sun goes down. At sunset, the rock formations glow, and you'll often find photographers behind their tripods waiting for magnificent rays to descend on Delicate Arch or other popular sites. The Fiery Furnace earns its name as its narrow fins glow red just before the sun dips below the horizon. Full-moon nights are particularly dramatic in Arches as the creamy white Navajo sandstone reflects light, and eerie silhouettes are created by towering fins and formations.
