Its highest elevation is 5,653 feet (1,723 m) at Elephant Butte, and its lowest elevation is 4,085 feet (1,245 m) at the visitor center. Forty-three arches have collapsed due to erosion since 1970. The park receives 10 inches (250 mm) of rain a year on average.

The national park lies atop an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area.

Climbing on named arches within the park has long been banned by park regulations. Following Dean Potter's successful free climb on the Delicate Arch in May 2006, however, the wording of the regulations was deemed unenforceable by the park attorney. The park revised its regulations as follows in response: All rock climbing or similar activities on any arch or natural bridge named on the United States Geological Survey 7.5 minute topographical maps covering Arches National Park are prohibited.

Climbing on other features in the park is allowed, but regulated. The revised regulations also prohibit slacklining parkwide. Approved recreational activities include auto touring, backpacking, biking, camping, and hiking, some of which require permits. Guided commercial tours and ranger programs are also available.
