Willow Pass
Peak · 10,084 ft · Yosemite corridor
Willow Pass is a 10,084-foot peak in the Yosemite corridor of California's Sierra Nevada, sitting at the crest of the high-altitude spine where easterly and westerly weather systems collide.
Wind dominates here. The pass funnel accelerates afternoon gusts; the 30-day average wind is 13 mph but peaks exceed 36 mph. Morning calm gives way to sustained flow by midday. Expect exposure on all approaches; snowpack in winter and spring adds avalanche hazard.
Over the past 30 days, Willow Pass averaged a NoGo Score of 34 with temperatures around 24 degrees Fahrenheit and wind averaging 13 mph. The week ahead shows the same baseline pattern: high-elevation spring conditions with avalanche terrain still active, wind picking up through the afternoon, and crowding remaining light. Plan for early starts and descents before wind strengthens.

About Willow Pass
Willow Pass sits on the Sierra crest between Tenaya Lake and Lee Vining Canyon, marking the transition from the Yosemite high country to the White Mountains. Access via Highway 120 (Tioga Road) from the west or from Lee Vining via Highway 395 on the east; the peak is a climb from the pass saddle itself, not a roadside marker. The pass road typically opens late spring and closes by early November depending on snowpack. From Yosemite Valley or Mono Basin, count 1 to 3 hours of driving. Base popularity is low, which means parking and crowds are rarely limiting factors.
Spring and early summer define conditions here. The 30-day rolling average temperature is 24 degrees Fahrenheit; the year-round minimum drops to 7 degrees during winter. Wind averages 13 mph over 30 days but peaks above 36 mph. The pass sits in a classic gap where pressure gradients accelerate flow, especially in afternoon. Snowpack persists into early summer; avalanche terrain is present and instability is highest during warm spells or after precipitation. By late summer, snow melts except in cliff gullies and permanent patches. Fall brings crisp, calmer weather before winter storms return. Crowding averages 3 over 30 days, reflecting low baseline use.
This location suits high-country hikers, peak baggers, and Sierra traversers comfortable with exposure and self-rescue. Experienced climbers use the peak and pass for mountaineering training. Winter and spring travel demands avalanche awareness; many approaches funnel through steep drainage slopes. Wind-sensitive activities like photography or stationary observation are best tackled before 10 a.m. Parking at the pass saddle is limited but uncontested. The pass road itself is the primary hazard in off-season; check Highway 120 status before departure. Snow-slogging in spring requires microspikes or crampons and route-finding skill on whitened terrain.
Nearby peaks along the crest (Cathedral Range to the west, Lee Vining peaks to the east) share the same wind and avalanche patterns. Tenaya Lake, just west of the pass, is calmer but at lower elevation. Tioga Lake to the east offers fishing and a car-accessible base for alpine rambles. Highway 395 communities (Lee Vining, June Lake) provide lodging and supply runs; Yosemite Valley gateways (Crane Flat, Tuolumne Meadows) lie an hour or more to the west.
