The City of Rocks National Reserve is a Bortle 2 scale site with excellent dark skies due to its distance from cities and other light pollution.
Located approximately 2 miles north of the border with Utah, the reserve is widely known for its enormous granite rock formations and excellent rock climbing. The rock spires in the City of Rocks and adjacent Castle Rocks State Park are largely composed of granitic rock.
During the 1840s and 1850s, when wagon trains on the California Trail left the Raft River valley and traveled through the area and over Granite Pass into Nevada, the travelers would notice the large granite stones resembled city buildings in a way. The area’s historical and geological values, scenery, and opportunities for recreation led to its designation as City of Rocks National Reserve in 1988. This unit of the National Park System is managed cooperatively by the National Park Service and the Idaho Department of Parks and Recreation.
