The route
The Sierra Nevada is the backbone of California, and this 262-mile route crosses it twice. Begin in Gold Country before climbing State Highway 108 through pine forest to Sonora Pass. The final approach is narrow, steep and highly seasonal.
The eastern descent reaches the Walker River valley and US 395, then turns south through Bridgeport and Conway Summit to June Lake Loop. From Lee Vining, Tioga Road climbs into Yosemite's high country before continuing through Tuolumne Meadows to Yosemite Valley.
Sonora Pass and Tioga Road close seasonally and can be affected by snow, fire, rockfall and emergency repairs. Confirm both roads with Caltrans and the National Park Service immediately before departure.
