The National Reserve

A National Reserve is a unit of your
National Park System. National Reserves,
however, are usually administered jointly
by the National Park Service and a state
or local agency. City of Rocks National
Reserve is managed by the National Park
Service and Idaho Department of Parks
and Recreation.

The Reserve, authorized by Congress
on November 18, 1988, contains over
14,300 acres. Approximately half of the
land is public property. The other half
is privately owned. Respect for private
property is important. Observe posted
signs, leave gates as you found them
and unse only established roads, trails
and existing camp sites.

City of Rocks was named by emigrants
traveling the California Trail during the
mid-1800s. The granite spires, domes,
ramparts, and monoliths reminded them
of an ancient city. The California Trail
passes through the Reserve from the
direction of Almo, via Pinnacle Pass
and Granite Pass. Over 200,000 pioneers
traveled this trail on their way west,
many in search of California gold.

There are many things to do and points
of interest to see in City of Rocks National
Reserve. Rock climbers from all over the
world come here to climb rocks, like Elephant
Rock, Bath Rock, and the Twin Sisters.
History buffs seek out the ruts and markings
of the California Trail at Pinnacle Pass and
other sites. Campers and hikers find camping
spots where they can explore the ridges
and canyons of "the City." Photographers
find dramatic opportunities, from the
magenta or yellow flower of prickly pear
cactus to spectacular cloud formations
and sunsets.

City of Rocks is a special place, a gem in
the Gem State.
