Why this place matters

City of Rocks

Described by California Trail emigrants as “a city of tall spires,” “steeple rocks,” and “the silent city,” this awe-inspiring landscape continues to captivate. Today, it beckons rock climbers, hikers, campers, hunters, and adventurers with its dramatic scenery, fascinating geology, and echoes of the Old West.
