Tuolumne County Travel Information

Traveling to Yosemite

Travel by car
There are four major entrances into the park. All of these routes are relatively windy mountain roads and appropriate time should be budgeted for them.

Highway 120 from the west from Stockton or Modesto. (Map of Tuolumne County)
This is the fastest route from locations west (Bay Area) and northwest (Sacramento). Route 120 is a bit steep, so RVs and trailers should consider Route 140 instead. In winter, snow makes the lower elevations of Route 140 more attractive.

Climate
Weather can change rapidly during all seasons of the year, and will also vary greatly with elevation. When visiting it is wise to pack for any season with clothing that can be layered, ready to peel off or add on as conditions dictate. Always include some kind of rain gear; the park receives most of its precipitation in the months of January, February and March, but storms are common during the transitional spring and fall seasons, and spectacular thunderstorms may occur during summer.

For Yosemite Valley and Wawona (subtract 10-20°F (5-10°C) for Tuolumne Meadows), average weather is as follows:

Summer:
Typically dry, with occasional thunderstorms; temperatures from 50°F (10°C) to the low 90°F (30°C) range.

Fall & Spring:
Highly variable, with typical high temperatures ranging from 50-80°F (10-27°C) , with lows from 30-40°F (-1 to 4°C). Rain is less likely early in fall/late in spring and rain or snow is likely late in fall/early in spring.

Winter:
Snowy, rainy, or (sometimes) even sunny days are possible, with highs ranging from 30-60°F (-1 to 16°C) and lows in the high 20°F (-4 to 0°C) range.
