Crystal Peak, Mountain summit in Sierra County, United States.

Crystal Peak is a mountain at the south end of the Bald Mountain Range in Sierra County, California, rising 2,461 metres above sea level and about 91 metres above the surrounding terrain. It stands 4.8 km northeast of Sardine Valley and 25.6 km northwest of Reno, Nevada, and the Crystal Mine lies on the peak.

The first documented expedition reached this summit in 1845 when a wagon train from the Stevens area arrived in the Sierra Nevada. This early exploration established the mountain in historical records.

Crystal Peak takes its name from the quartz crystals found at the site, and the Crystal Mine on the mountain is open to the public as of 2020. Collectors may take up to one 5-gallon bucket of crystals per vehicle per week. The first recorded visit to the peak was in 1845 by a Stevens wagon train.

The summit is accessible via hiking trails that depart from different trailheads in the region, with routes varying in difficulty depending on your chosen path. Visitors should bring warm layers and plenty of water, as the exposed peak experiences rapid weather changes.

Crystal Peak's summit sits at 2,461 metres, rising about 91 metres above the surrounding terrain, and the mountain gave its name to the Crystal Mine worked on its slopes. Since the town of Crystal was abandoned, the access roads decayed until they were rebuilt in 1992. Today collectors may take one five-gallon bucket of crystals per vehicle per week.
