Sonora Pass

Sonora Pass, an unforgettable journey in California

Sonora Pass is a high mountain pass at an elevation of 2.933m (9,624ft) above the sea level, located in Sierra Nevada, in Mono County, California, United States. It's one of the highest mountain roads of California.

The road to the pass is asphalted. It’s called State Route 108. The road turns so sharply in places that you’ll see cars almost stop going around corners. It’s a true mountain road, very beautiful through alpine meadows.

Is Sonora Pass dangerous?

The road includes some steep sections and is pretty narrow. The highway over the pass is extremely steep (exceeding 8% for most of the traverse, and up to 26% grades in some locations), narrow and winding between Kennedy Meadows on the west side and Leavitt Meadows on the east. The route is not recommended for vehicles or vehicle combinations that are unusually wide, heavy or long.

Is Sonora Pass open?

When the snow falls - which it does in the winter – things get tough and slippery. Open to vehicles in summer only. The pass usually remains open until the first heavy snowfall of the winter arrives. Often that occurs sometime in early November, but snow can temporarily close the pass at any time. Traditionally the pass re-opens in mid-May, but once again, even after it opens, late season storms can cause it to close again.

How long is Sonora Pass?

The road is 47km (29.5 miles) long running west-east from Dardanelle (in Tuolumne County) and Sonora Junction (in Mono County). Travel this road to see some of the most spectacular views in the region. It’s an unforgettable journey.
