City of Rocks National Reserve

City of Rocks National Reserve lies in south-central Idaho within the northern edge of the Basin and Range geologic province. This unique area offers scenic walks near the historic California Trail and opportunities for photography, world-class technical rock climbing, hiking, bird watching mountain biking, horseback riding, picknicking, and camping.


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 visitor center, located in Almo, Idaho, and the wayside exhibits, located along main roads throughout the park, provide opportunities to become acquainted with the Reserve's historical significance and special resources.

There are 64 standard campsites with tables and fire rings. Most campsites also come equipped with a tent pad. Water stations and vault toilets are centrally located throughout the reserve.  Cabins, bed & breakfasts, restaurants, natural hot springs, auto services, and a general store, are located in Almo.
