City of Rocks National Reserve
This unique geologic area became a landmark in 1843 for California-bound emigrants. They left wagon ruts across the landscape and their signatures in axle grease on Register Rock, Camp Rock and many others.
A few granite pinnacles and monoliths are in excess of sixty stories tall and 2.5 billion years old. The smooth granite faces offer exceptional rock climbing. Today, over 500 climbing routes have been identified.
The Reserve is managed by the Idaho Department of Parks and Recreation under a cooperative agreement with the National Park Service.
