Tioga Pass Entrance
Trailhead · 9,943 ft · Yosemite corridor
Tioga Pass Entrance, at 9943 feet on the Yosemite corridor's eastern threshold, sits where the Sierra Nevada meets high desert. The pass is California's highest highway crossing and the gateway to Yosemite's eastside.
Wind accelerates through the pass as pressure systems move across the high desert. Mornings are typically calmer; afternoons funnel sustained gusts. Temperature swings are sharp between sun and shadow. Snow lingers into early summer, and avalanche terrain demands awareness on steep approach slopes.
Over the last 30 days, the average NoGo Score has held at 45.0, with temperatures averaging 25 degrees Fahrenheit and wind averaging 10 mph. Late April to early May typically sees the pass transition from winter closure risk to spring accessibility. Watch the 7-day forecast for wind spikes above 15 mph and sudden temperature swings that signal rapid snowpack change.

About Tioga Pass Entrance
Tioga Pass Entrance sits at the junction of Highway 120 and the Mono Basin, 10 miles east of Tenaya Lake and directly above Mono Lake at nearly 10000 feet elevation. Access from the west requires traversing the full width of Yosemite; from the east, US Route 395 delivers you from Lee Vining (a 45-minute drive). The pass is the highest and most exposed of Yosemite's entrances. Winter closures are common; Highway 120 can shut for weeks when snowpack and wind combine. Check Caltrans and NPS updates before committing to a trip.
The 30-day average temperature of 25 degrees Fahrenheit masks the real character of this place. Winter lingers into May; summer arrives briefly in July and August before retreating by September. Wind is the dominant variable. The 30-day average wind is 10 mph, but gusts routinely reach 30 mph, especially in afternoon. Morning departures before 10 AM offer the calmest windows. Crowding is low year-round (average 13.0 on the NoGo scale), but parking fills rapidly on the rare clear weekends when the pass is open. Visibility and snowpack stability change faster here than in lower elevations due to exposure.
Tioga Pass Entrance serves backcountry entry to the High Sierra Camps loop, Cathedral Lakes, and the eastern High Sierra Wilderness. Most visitors are through-hikers planning multi-day routes, not day-use crowds. Winter and early spring climbers target the approach for alpine objectives on the peaks directly above; avalanche terrain is real and requires beacon, probe, and shovel discipline. Experienced mountaineers use the pass as a launch point. Casual hikers find it less welcoming than Yosemite Valley entrances due to exposure, limited facilities, and weather volatility. Late September through early October is the sweet spot for both stability and weather cooperation.
Nearby alternatives include Tenaya Lake (lower elevation, less wind, higher crowding) and Lee Vining Canyon (eastern access, dry approach, scenic canyon drive). The Mono Basin itself (Mono Lake, Crater Mountain, Inyo National Forest) offers less dramatic but more stable September-through-October conditions. If Highway 120 is closed, rerouting via US 395 and Highway 158 over Monitor Pass adds significant time but keeps the region accessible. Tioga Pass is a corridor destination for serious Sierra travelers; casual recreation is best pursued elsewhere.
