City of Rocks National Reserve


In the high desert of southeast Idaho stands a collection of granite spires that served as a welcome rest stop along the California Trail.   At the height of the gold rush in 1852, some 50,000 pioneers passed this site in a single year.  Many left their names painted in axle grease, still legible on Camp Rock and Register Rock.  Today it is a popular destination for rock climbers from around the world, but also has 22 miles of hiking and equestrian trails.

Must-Do Activity

Rock climbers flock here from around the world to take on the granite spires that inspired emigrants on the California Gold Rush Trail to name it City of Rocks.  The grippy granite is fun for any skill level to clamber around on and easily accessible from all campsites.

Best Trail

Trails snake through this area leading to different climbing routes, especially around Elephant Rock, which is a great place to watch other climbers.  Keep watching the skies, too, as a variety of raptors (and pigeons) enjoy the thermals here.

Window Arch is a great place to watch the sun come up, just try not to wake up campers in the neighboring sites.

Peak Season

Summer, since it is very cold at this elevation (7,000 feet) in other seasons.  Autumn briefly turns aspen leaves yellow.



Free to enter and only $12.72 to camp per night (so bring exact change)

Road Conditions

A dirt road winds through the park and is accessible to passenger vehicles.


78 primitive campsites located off the dirt Emery Canyon Road, with several nice sites sit right next to Window Arch.  For more upscale accommodations try the Lodge and Bunkhouse at nearby Castle Rocks State Park.
