Established in 1988 as a national reserve, City of Rocks encompasses 14,407 acres of land (about one quarter is privately owned) and is renowned for its scenic, geologic, and historic significance.

The City of Rocks area was an important landmark on the California Trail. City of Rocks is one of the finest granite-face climbing sites anywhere. Climbers find the younger granite of the Almo Pluton to be some of the best rock they’ve ever ascended. About 700 routes have been developed to date. City of Rocks also has ample access to hiking, mountain biking, and horseback riding.

Winter at City of Rocks

The winter months provide excellent opportunities for snowshoeing and skiing. With 22 miles of trails in the City of Rocks and another 12 miles in Castle Rocks, snowshoers and cross-country skiers can find deep quiet — and even see some of the area’s wildlife. You won’t find groomed trails, but you will find solitude and fantastic geological features.
