Yosemite Road Conditions

Enjoy a double dose, as you cruise through Yosemite Mariposa County’s picturesque highways. You can read on to find out about Yosemite road conditions, before you make your trip.

Seasonal Yosemite Road closures

Yosemite's roads tend to be clear and accessible all year. However, there are some exceptions such as Tioga Road and Glacier Point Road.

Highway 41, Highway 120 ,Highway 108 re at higher elevations so snow is more likely (and Chain controls). Highway 140, also known to be the All-Weather Highway and has a lower elevation, so it is less likely to get snow.

The road from Hetch Hetchy to the city is open throughout the year, but it is closed during daylight hours.


Annual Tioga Road Closure

This view overlooks Tenaya Lake and is just one of many iconic views along Tioga Road. This high-altitude road crosses the park between Crane Flat and Lee Vining.

Tioga Road is only available during the summer months. This section of Highway 120  runs east through Tioga Pass, east of the Sierra. This road is blocked by deep snow and dangerous avalanche hazards in winter. It is difficult to predict when this road will open each season as it depends upon the weather. However, Tioga Road closes around November. The road re-opens in May and June.

A better view of the historic opening and closing dates can be obtained. If you're interested in tracking the progress on the last stretch, the National Park Service will post occasional plowing reports starting in mid-April.


Annual Glacier Point Road Closure

Half Dome is seen from Glacier Point Road's U-Bend.

Glacier Point Road (off Highway 41) is a spur that takes you to beautiful overlooks like Glacier Point. This road is only accessible to Badger Pass, Ski Area in winter. The road is open for cross-country ski. On the tracks' outside edges, snowshoers can be found.

NPS also has tracked the dates of Glacier Point Road's opening and closing since 1995. NPS will post plowing progress while they work to make the road accessible in the spring.

Note : The Glacier Point Road has been closed to traffic during the summer months.


Mariposa Grove

The Mariposa Grove Road are usually open around March 15. They will close around November 30.

Mariposa Grove Road is forbidden for most people. The Welcome Center is closest to the South Entrance Gate. It's possible to hike the 2 mi (3.2 km) Washburn Trail or to take a shuttle bus, if there are any. If you are a person with a disability placard or license plate, you can also drive to the Arrival Area.

Mariposa Grove Road cannot be plowed in winter. It becomes impassible to cars, but cross-country skiers snowshoers snowshoers or hikers frequently enjoy the journey along the winter road.

Notice: Following a catastrophic Mono Wind event in the early 2021s, Mariposa Grove Road & shuttle system were closed to vehicles. We are still waiting for information on when the system might reopen.

Plan For Relaxing Summer Travels

Yosemite boasts stunning views that attract visitors from all corners of the globe. It is easy to find parking and navigate transportation when it is hot. Plan ahead and avoid returning to your vehicle in the middle of the afternoon. We recommend that you plan your trip so that Yosemite's entrance is reached before 9:00 am. But, it doesn't hurt to get there earlier.

You should also look into public transportation options. These include YARTS and free shuttles to Yosemite Valley. A great way to explore Yosemite Valley are bicycles. Bicycling is fun and you can stop whenever the view calls. If you don’t have a bicycle.
