Driving SR-108 to Dodge Ridge
Highway 108 from Sonora is the primary route to Dodge Ridge Ski Area, climbing from the Central Valley through Sonora and into the Sierra Nevada. The resort sits just off SR-108, making it one of the more straightforward mountain resort drives in California. Beyond Dodge Ridge, Sonora Pass itself reaches 9,624 feet — the second-highest paved pass in California — but that section closes in winter.

The Drive from Sonora

Above Pinecrest, you are in genuine Sierra Nevada terrain with snow, ice, and steep grades. Dodge Ridge is approximately 7 miles past Pinecrest.

Local Tips
- Fill Up in Sonora: Gas is available in Sonora. Prices climb above town. Top off before the mountain section.
- Pinecrest is the Last Stop: Pinecrest Lake has limited services including a small store. Stock up here if needed.
- Lower Traffic Than Tahoe: SR-108 to Dodge Ridge sees a fraction of the traffic of I-80 or US-50. Weekends are manageable compared to Tahoe highways.
- Morning Ice: Shaded sections near Pinecrest and above can be icy in the morning even without active snowfall. Drive carefully on cold clear mornings.
