Green Creek Trailhead
Trailhead · Yosemite corridor
Green Creek Trailhead sits at 8,035 feet in the high Sierra east of Yosemite, offering direct access to alpine meadows and peaks. Wind and exposure dominate; plan carefully.
Wind funnels through the drainage consistently, averaging 15 mph over the past month with gusts to 33 mph. Mornings are calm relative to afternoons. The trailhead is windier and colder than Yosemite Valley due to elevation and east-facing exposure; expect snow or wet slush in shoulder seasons.
Over the last 30 days, Green Creek Trailhead averaged a NoGo Score of 17.0, with temperatures holding around 25 degrees Fahrenheit and wind averaging 15 mph. The week ahead will show typical spring volatility at this elevation. Watch the forecast grid for wind spikes in the afternoon column and temperature swings tied to cloud cover.

About Green Creek Trailhead
Green Creek Trailhead serves the high-Sierra drainage system east of the Yosemite corridor, accessed via US Route 395 north from Mammoth Lakes or south from Lee Vining. The trailhead sits at 8,035 feet, making it one of the higher Sierra access points for alpine hiking and climbing. The approach is straightforward but weather-dependent; the final miles of road climb steeply and can be snow-choked or washed out in early season. Nearest services and fuel are at Lee Vining, roughly one hour drive south. The trailhead itself is exposed, with minimal shelter and no buildings; arrive prepared for sudden weather shifts.
Conditions at Green Creek reflect high-Sierra spring and early-summer weather patterns. The past 30 days show an average temperature of 25 degrees Fahrenheit, with 365-day lows touching 10 degrees and highs to 40 degrees Fahrenheit. Wind is the dominant player: the 30-day average of 15 mph masks afternoon gusts to 33 mph, particularly on clear, high-pressure days when solar heating drives drainage wind. Mornings are typically calm for two to three hours after dawn. Crowding averages 13 visitors over the rolling 30 days, reflecting the trailhead's lower popularity relative to main Yosemite Valley and Tuolumne Meadows access. Snowpack lingers into late spring; check current conditions with the local ranger district before committing.
Green Creek Trailhead is best for experienced alpine hikers comfortable with wind exposure and self-sufficiency. Climbers targeting the peaks in the Green Creek drainage use this as a gateway; day hikers tackling the meadow systems also start here. The trailhead attracts fewer casual visitors than more famous corridors, so parking pressure is light even on weekends. What separates success from frustration is timing: head out on calm mornings between dawn and 10 a.m., before afternoon wind establishes. Skip the afternoon if you are light, towing a heavy pack, or managing a large group. Weather windows in spring are brief and changeable; a clear dawn can turn to snow squalls by noon. Bring layers and a windproof shell regardless of forecast.
Nearby alternatives include the Tioga Pass area trailheads and Mono Basin access points to the south. The Yosemite high country (Tuolumne Meadows, Cathedral Lakes) lies west; those trailheads see higher traffic and similar wind exposure but offer more shelter in established campsites. Green Creek's appeal is isolation and directness: fewer people, but also no infrastructure. If crowding is your main concern, Green Creek delivers. If you need reliable afternoon weather, the lower-elevation Yosemite Valley trails are a better bet. Plan for the 30-day average wind of 15 mph as your baseline and treat calm mornings as bonuses, not the rule.
