Tioga Pass
Peak · 9,942 ft · Yosemite corridor
Tioga Pass is a 9,942-foot peak commanding the Sierra Nevada crest where Highway 120 crosses into Yosemite. Wind funnels hard across the pass; conditions flip hourly between calm and punishing.
Tioga Pass sits fully exposed on the crest. Wind accelerates through the gap between peaks and peaks in afternoon. Temperature at 9,942 feet runs 10 to 15 degrees colder than Yosemite Valley. Morning calm windows close by midday; head early or expect sustained gusts.
Over the last 30 days, Tioga Pass averaged a NoGo Score of 34 with an average wind of 10 mph and temperatures near 26 degrees Fahrenheit. The week ahead will likely hold similar patterns: watch for afternoon wind spikes and check avalanche conditions with SAC before any winter approach. Morning light crossing the pass typically offers the steadiest windows.

About Tioga Pass
Tioga Pass sits at the Sierra crest where California Highway 120 crosses from Mono County into Tuolumne County on the Yosemite corridor. The pass itself is a named saddle and peak at 9,942 feet. Lee Vining, California lies about 45 minutes east; Groveland sits roughly 90 minutes west via Highway 120. The pass is the primary eastern gateway into Yosemite; Highway 120 is the most direct high-country link between the Eastern Sierra and Yosemite Valley. Access is straightforward: drive up from Lee Vining or down from Crane Flat. Winter closures are common; the pass typically opens late spring and closes by early November depending on snowpack.
Tioga Pass sits fully exposed at the Sierra crest with no shelter from wind funneling north-south along the ridge. The 30-day average wind speed is 10 mph, but gusts regularly reach 30 mph in afternoon hours. Temperature averages 26 degrees Fahrenheit over the rolling 30 days and ranges from 10 to 38 degrees Fahrenheit annually. Crowding is minimal (average 3 out of 10) because the pass is a highway crossing, not a destination. Late spring through early fall, the pass is passable most days; winter snow and wind close it for weeks. Spring snowmelt and afternoon thermal wind create the most unstable conditions. Avalanche terrain exists on both sides of the pass; check the Sierra Avalanche Center advisories before any off-highway travel.
Tioga Pass is primarily a transit corridor rather than a hiking or climbing destination, but winter mountaineers, ski tourers, and backcountry travelers use it to access high-country routes. Experienced winter travelers plan around avalanche risk, unpredictable snow conditions, and wind that can strand vehicles. Summer visitors crossing the pass on foot or bike encounter minimal crowds and cold wind even at midday. Parking at the pass itself is limited; most traffic flows through rather than stops. If you are planning an approach from the east side, expect minimal services beyond Lee Vining. The pass closes entirely in heavy snow; check CalTrans Highway 120 status before driving.
Nearby Mono Basin and the Eastern Sierra offer gentler frontcountry alternatives: Mammoth Mountain to the south receives more reliable summer conditions and higher crowds. Yosemite's high country west of the pass (Tenaya Lake, Tioga Road pullouts) sits at similar elevation but typically offers slightly more shelter. The Mono Craters and glass peaks east of the pass attract winter mountaineers comfortable with avalanche terrain. Tioga Pass itself remains the coldest, windiest, most exposed crossing on the Yosemite corridor; solitude comes at the cost of weather reliability and high wind.
