WINTER TRAVEL

Highway 120 is open year-round between Tuolumne County destinations and Yosemite National Park and into Yosemite Valley. 

Both Tuolumne County mountain passes, Sonora Pass (Highway 108) and Tioga Pass (Highway 120 east in Yosemite) are closed in the winter.  Although closing and opening dates vary by season; the two routes are generally closed mid-November through mid-May or early June. Alternate routes over the Sierra Nevada include Highway 88 or Highway 50 to the north or Highway 58 to the south.

It is always advisable to carry chains in the mountains during the winter. Tire chains are available at Yosemite Adventure Supply in Groveland (along Highway 120) and in auto parts stores in Sonora for Highway 108 travel.
