Donner Peak, Mountain summit in Placer County, California.

Donner Peak is a mountain summit in the Sierra Nevada, rising about one mile southeast of Donner Pass. The terrain offers hikers views of surrounding slopes and the high mountain landscape of the region.

In 1865, workers of the Central Pacific Railroad drilled tunnels through the northern cliff faces to establish a railroad route across the Sierra Nevada. This was a crucial step in connecting the West Coast with the rest of the country.

The Pacific Crest Trail passes along the western slope of Donner Peak, offering hikers panoramic views of the surrounding Sierra Nevada mountains.

The round trip to the summit covers 3.5 miles (5.6 km) with 940 feet (290 m) of elevation gain, approaching from Donner Pass along the Pacific Crest Trail on the west slope. Snow lingers late at this elevation, so check conditions before setting out.

The 411.5 inches (10.45 m) of snow recorded annually belongs to Donner Pass, one mile northwest of the summit, not to the peak itself. The peak's own toponym was officially adopted in October 1940 by the U.S. Board on Geographic Names, after appearing on an 1873 California Geological Survey map.
