California’s Eastern Sierra

Sonora Pass

Sonora Pass is a scenic, mountain recreation thoroughfare that connects to Highway 395 in the Eastern Sierra.

Travel to Sonora Pass

Highway 108 (Sonora Pass Road) runs east-to-west through scenic National Forest lands across the Sierra Range near Bridgeport, California. The pass connects Mono and Tuolumne Counties about an hour north of Mammoth Lakes, California on Highway 395. The pass is narrow and steep in spots, so it is not recommended for long or large vehicles. Open to vehicles in summer only.

Winter Snowmobiling

Sonora Pass at Bridgeport Winter Recreation Area

Sonora Pass is unplowed in winter, so when snow falls from November through May, access to Sonora Pass is great for snowmobilers, snowshoers and cross country skiers. Experienced snowmobilers will enjoy the excellent snow conditions and challenging terrain in the Bridgeport Winter Recreation Area. The area provides the opportunity to experience extreme winter sports unmatched anywhere in the Sierra Nevada. Permits are required to use the area but are free of charge - contact the Bridgeport Ranger Station, (760) 932-5899, for info on permits and maps. You can request a permit up to 24 hours in advance Monday - Friday between 8am and 2pm. For more information visit the Humboldt-Toiyabe Forest Service
