The sights at Arches are rare and diverse. Dozens of arches offer spectacular views. Perhaps the most famous arch in the park is Delicate Arch.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.
Astronomy is also popular in the park due to its dark skies despite the increasing light pollution from towns like Moab. You can also see single arches, doubles arches and more whether you look straight ahead or up. A rounded arch like this one gives a perfect view of the night sky. Arches National Park at dark is a delight for photographers.
