Sonora Pass

Sonora Pass is a mountain pass in the Sierra Nevada where State Route 108 crosses at an elevation of 2933 meters (9623 feet). The road connects Alpine County with Mono County and passes through mountain terrain with several viewpoints and natural transitions.

The pass became an essential route during the California Gold Rush, when miners and settlers needed to move between eastern and western parts of the Sierra Nevada. This traffic shaped the early development of the surrounding region.

The Pacific Crest Trail crosses through Sonora Pass, drawing long-distance hikers who travel the mountain terrain during summer months. This route connects different regions and gives hikers a natural pathway through the mountains.

The pass closes from November to April due to snow and winter conditions, with snow removal beginning the first Monday in April. Visitors should prepare for strong winds, harsh conditions, and limited services, especially outside the warmer months.

Near the pass, the United States Marine Corps operates a Mountain Warfare Training Center where soldiers learn high-altitude tactics. This military facility blends training operations with the natural mountain landscape, and most travelers never notice it.
