North Glacier Pass
Peak · 11,190 ft · Yosemite corridor
North Glacier Pass sits at 11,190 feet in the Yosemite corridor's high Sierra. A glacially-sculpted saddle between major peaks, it commands exposure to afternoon wind funneling off alpine lakes.
Wind climbs steadily from mid-morning onward, peaking in the afternoon. The 30-day average of 12 mph masks gusts to 33 mph when systems move through. Early starts yield calm; plan to descend by early afternoon. Snow lingers into late spring; avalanche terrain is active on the approach slopes.
Over the last 30 days, North Glacier Pass averaged a NoGo Score of 34, with temperatures holding at 22 degrees Fahrenheit and winds averaging 12 mph. The week ahead will track typical late-spring patterns: morning windows remain the rule, but crowding stays light as snow still blocks easy access from lower elevations. Watch for rapid afternoon wind rise and unstable snowpack on steeper pitches.

About North Glacier Pass
North Glacier Pass is a high-alpine saddle at 11,190 feet on the east rim of Yosemite's high country, sitting in the Sierra Nevada's glaciated terrain north of the park's interior. Access is primarily from Tioga Road (Highway 120) via the Tenaya Lake drainage or from the east side via Mono Basin approaches; the nearest gateway is Lee Vining, roughly 50 miles southeast. Winter and early spring require snowpack travel; the pass is snow-covered from October through May, making it a backcountry ski or snowshoe objective rather than a summer trail destination. Late-season and shoulder-season visitors approach via wilderness trails as snowpack retreats.
Conditions at North Glacier Pass are shaped by elevation and exposure to weather systems crossing the Sierra crest. The 30-day rolling average of 22 degrees Fahrenheit reflects the high-altitude, late-spring window; temperatures swing from a 365-day minimum of 8 degrees in winter to a summer maximum around 33 degrees. Wind is the dominant constraint: the 30-day average of 12 mph understates variability, with recorded gusts to 33 mph. Afternoon heating drives upslope flow, funneling wind through the pass by 2 p.m. onward on most days. Crowding remains very light (30-day average of 3 out of 10) because access requires substantial snowpack skills or multi-day wilderness travel. The pass is rarely crowded even in peak season.
North Glacier Pass suits experienced mountaineers, ski mountaineers, and backcountry travelers comfortable with alpine navigation and avalanche terrain. The approach involves sustained climbing over glaciated and steep terrain; snow stability assessment and crevasse awareness are mandatory. Plan for dawn departures to maximize the calm-wind window. Afternoon descent in rising wind is dangerous and tiring. Most visitors pair the pass with multi-day traverses of the high country rather than day trips. Parking at Tioga Road trailheads fills on summer weekends, but the pass itself sees only a handful of parties per week even in August.
Nearby alternatives include Cathedral Pass (10,300 feet), Mono Pass (10,604 feet), and Budd Lake, all accessible from the same Tioga Road corridor but lower in elevation and with gentler snow regimes. North Glacier Pass is significantly higher and more exposed; the trade-off is broader views and sustained alpine terrain. Visitors with less avalanche experience or shorter time windows often head to Tenaya Lake itself or Cathedral Lakes, both at lower elevations with earlier accessibility.
