Visitors to the City of Rocks National Reserve in south central Idaho will find a striking landscape with unparalleled opportunities for rock climbing, hiking, camping, wildlife watching and other forms of outdoor recreation. The remarkable granite spires found here date back more than 2.5 billion years and attract rock climbers from around the world.  

Back in 2009, the Fund helped add the nearly 1250-acre Castle Rock Ranch to this reserve thanks to a complex land exchange involving the National Park Service, the Idaho Department of Parks and Recreation.  This property is a key tract of private land located within the western entrance of  City of Rocks National Reserve, along the California National Historic Trail (NHT).  Now it is open to climbers, hikers and horseback riders who visit the reserve and the adjacent Sawtooth National Forest.

Protecting this land will help the National Park Service tell the story of western trailblazers’ historic journey along the California NHT by protecting the 160-acre tract’s historic wagon ruts and outstanding scenery. The public now can enjoy access to the property and a greater appreciation of the courage and hardships of mid-19th century pioneers that settled in the western United States.
