Tioga Pass

Tioga Pass is a mountain pass straddling the border between Tuolumne County and Mono County, serving as the eastern gateway to Yosemite National Park via California State Route 120. It sits at roughly 3031 meters elevation and connects the Sierra Nevada range to the Great Basin region beyond.

The route began as the Great Sierra Wagon Road starting in 1883 to serve mining operations in the region. It was later converted into a paved highway in 1937, establishing a lasting connection across the mountains.

Native American tribes established trading routes through this area as early as 2000 BC, exchanging items such as obsidian, acorns, and salt.

The pass remains accessible only during summer months, typically from late May through October, as winter storms can close the road for extended periods. Travelers should check conditions before driving, particularly near the season's edges when weather changes rapidly.

The annual Tioga Pass Run attracts athletes each September who challenge themselves on the steep climb under the high altitude conditions. This running event has become a well-known test for those seeking to push their limits in one of California's most remote mountain passages.
