Robinson Peak
Peak · 10,741 ft · Yosemite corridor
Robinson Peak rises at 10,741 feet in the Yosemite corridor of the Sierra Nevada. High-elevation approach across alpine terrain with avalanche hazard in winter and early spring.
Wind dominates at elevation; the 30-day average runs 14 mph with gusts to 33 mph. Afternoon strengthening is typical. Temperature swings from 7 to 36 degrees Fahrenheit across the year. Expect exposure and thin air above treeline.
Over the last month, Robinson Peak averaged 14 mph wind and a NoGo Score of 32, marking it as frequently marginal. Winter and early-spring visitors must assess avalanche terrain daily; the high-country snowpack instability extends through April. The week ahead will test your tolerance for wind and altitude.

About Robinson Peak
Robinson Peak stands in the high Sierra east of Yosemite Valley, accessible via the Tioga Road corridor (Highway 120). The peak sits in remote, high-alpine country; approach routes are multi-hour scrambles from trailheads near Tenaya Lake or the eastern Sierra. Most climbers start from the west side via Yosemite National Park; eastern approaches from Highway 395 near Lee Vining add mileage and complexity. Winter road closures on Highway 120 typically extend through April, forcing longer detours north to Highway 395 or south to Highway 41.
Robinson Peak's weather reflects high-elevation exposure. The 30-day rolling average temperature stands at 22 degrees Fahrenheit, but annual extremes range from 7 to 36 degrees. Wind is the dominant feature: average 14 mph with recorded peaks of 33 mph. Spring and fall see the sharpest temperature swings and strongest winds. Summer offers the most stable conditions but draws crowds to the corridor. Winter approaches require avalanche awareness; the peak sits in terrain with significant snow-accumulation zones and gully systems prone to slab failure.
This peak suits experienced mountaineers and rock scramblers comfortable with routefinding above treeline, thin air, and self-rescue. Crowding is light year-round (3.0 average), reflecting the technical approach and high elevation. Plan for afternoon wind; morning starts before 6 a.m. yield calmer windows. Carry extra insulation and water; the alpine environment offers no shelter. Winter and spring ascents demand real-time avalanche consulting from the Sierra Avalanche Center and stable snowpack assessment. Navigation by map and compass is essential; cell service is unreliable.
Robinson Peak sits within striking range of other high-Sierra peaks including Tenaya Peak and Cathedral Range summits to the north. The Tioga Road corridor opens incrementally as snow recedes, unlocking access to Cathedral Lakes and Glen Aulin. Visitors comfortable with the approach will find fewer crowds here than on the main Yosemite Valley trails, but the isolation and technical exposure demand genuine alpinism skills.
