Winter Road Closures
The Tioga Road closes due to snow, usually from sometime in November through late May or early June. The road closure extends from the Tuolumne Grove, just east of Crane Flat, to Tioga Pass Entrance Station. (Highway 120, the continuation of the Tioga Road outside the park, is often closed in winter from Tioga Pass to five miles east of Lee Vining.)
When the Tioga Road is closed, it is not possible to drive to Tuolumne Meadows or enter Yosemite National Park from the east. All other park entrances, including those along Highway 120 from the west, Hetch Hetchy, Highway 140, and Highway 41, remain open all year.
The Glacier Point Road closes due to snow, usually from sometime in November through late May or early June. From approximately mid December through March, the first five miles of this road are open to Badger Pass ski area. It is not possible to drive to Glacier Point when the Glacier Point Road is closed.
The Mariposa Grove Road closes due to snow, usually from sometime in November or December through sometime in April. The road closure begins at South Entrance. Limited parking is available at South Entrance and it is possible to walk, snowshoe, or ski on the closed road. (It's two miles to the Mariposa Grove with an elevation gain of 500 feet; the road may be icy or snowy.)
All other park roads, including the Wawona Road (Highway 41), El Portal Road (Highway 140), Big Oak Flat Road (Highway 120 from the west), and the Hetch Hetchy Road are open all year. However, tire chains may be required late fall through early spring.
