(See plowing updates during spring road opening.)
Clearing of the Tioga Road begins on or about April 15 each year and usually takes between one and two months. Predicting when these roads will open is not possible, even in late spring, because weather in April and May can affect plowing progress significantly.
Note: Snowpack shows the percent of average for the Tuolumne River drainage (which includes the higher elevation areas of Tioga Road).
Caltrans has a list of recent closing and opening dates for other passes in the Sierra Nevada.
The only campgrounds listed are those with opening and closing dates that are based on conditions, which vary from year to year. Wawona, Hodgdon Meadow, and campgrounds in Yosemite Valley are not listed because they open and close on a fairly consistent schedule or are open all year.
(See table with this year's estimated opening and closing dates.)
* Notes by year:
The only trails that are routinely closed in Yosemite are the Mist Trail to Vernal Fall, the John Muir Trail between Clark Point and near the top of Nevada Fall (including the "ice cut"), and the Four Mile Trail.
