Norris Trailhead
Trailhead · Yosemite corridor
Norris Trailhead sits at 7,539 feet in the Yosemite corridor of California's Sierra Nevada. A high-elevation jump-off point typically calmer than windier passes to the north.
Wind averages 8 mph but ramps sharply in afternoon hours as thermals build off lower valleys. Morning calm dissolves by mid-afternoon. Cold persists even on mild days; expect 36 degrees Fahrenheit as the rolling average. Crowding remains light relative to Yosemite Valley proper.
Over the last 30 days, Norris Trailhead averaged a NoGo Score of 19 with temperatures holding near 36 degrees Fahrenheit and wind at 8 mph. The week ahead will show whether spring warming holds or rolls back; plan mornings for stability and reserve afternoons for lower-elevation traverses if conditions tighten.

About Norris Trailhead
Norris Trailhead anchors the northern Yosemite corridor at 7,539 feet, accessed via Highway 120 from Lee Vining or Tuolumne Meadows. The trailhead sits in the high-Sierra transition zone where snowmelt feeds multiple drainages. Parking is typically available even on weekends; the base popularity here is low relative to valley floors. Drive times from Lee Vining run 45 to 60 minutes depending on road condition and snow closure windows. Highway 120 opens fully in late spring and remains passable through early autumn.
Spring and early summer bring marginal conditions. Snowpack lingers past mid-elevation zones well into June; trails remain iced or boggy. Afternoon winds pick up as the season advances, with 30-day averages holding steady at 8 mph and gusts reaching 19 mph. Temperature ranges from a 365-day low of 21 degrees Fahrenheit in winter to a high of 53 degrees in summer. Crowding stays modest through the shoulder seasons but increases sharply during the first two weeks after Highway 120 reopens. Mornings deliver the calmest and most stable conditions; skip the trailhead after 2 p.m. if wind sensitivity is a concern.
This location suits climbers, backpackers, and high-elevation day hikers comfortable with cold exposure and thin air. Experienced users plan around snow closure windows and high-altitude weather swings. Parking capacity is ample, but services (fuel, water, supplies) require a drive back to Lee Vining or Tuolumne. Wind and temperature volatility demand layering and shelter-capable packs. Afternoon thermals and valley heating make early starts non-negotiable for stable conditions.
Nearby alternatives include Cathedral Lakes, Lyell Canyon, and the Tioga Pass drainage. Cathedral Lakes sits lower and warmer but receives more foot traffic. Lyell Canyon offers more sheltered northward access but demands longer commitment. Norris Trailhead competes less directly with Yosemite Valley trailheads; it serves the high-pass circuit and climbers targeting Sierra peaks rather than iconic granite formations.
