Avonelle Lake
Lake · 8,330 ft · Yosemite corridor
Avonelle Lake sits at 8,330 feet in the Yosemite corridor of California's Sierra Nevada. This glacially-carved alpine lake is accessed via Highway 120 and offers solitude typical of backcountry destinations.
Afternoon wind accelerates across the open water by mid-day; morning conditions are markedly calmer. Temperature swings from freezing at dawn to near 40 degrees Fahrenheit at peak heating. Wind funnels consistently off the basin; plan water activities before 11 AM.
Over the last 30 days, Avonelle Lake averaged a NoGo Score of 35, with temperatures near 25 degrees Fahrenheit and winds averaging 11 mph. The week ahead follows typical spring patterns for this elevation: expect morning windows of stability before afternoon wind climbs. Crowding remains light at 6 on the rolling 30-day average.

About Avonelle Lake
Avonelle Lake lies in the high Sierra backcountry east of Yosemite, accessed via Highway 120 through Tioga Pass. The lake sits at 8,330 feet, placing it in avalanche-prone terrain requiring standard winter and spring assessment before approach. Most visitors arrive from the Yosemite corridor side, driving through the park or via the eastern Sierra gateway. The basin is snow-fed and isolated; there is no maintained trail infrastructure or established parking lot. Access requires a full backcountry approach and stable snowpack evaluation through the Sierra Avalanche Center.
Spring conditions at Avonelle Lake are defined by temperature volatility and predictable afternoon wind. The 30-day average wind of 11 mph masks a typical morning-to-afternoon shift; calm conditions commonly exist before 10 AM, then strengthen as solar heating drives air across the open water. Temperature swings from a rolling 365-day minimum of 14 degrees Fahrenheit to a maximum near 39 degrees Fahrenheit; expect freezing nights through late spring. Crowding stays minimal year-round at a 30-day average of 6, a function of the difficult backcountry access and avalanche exposure. Snowpack duration extends late into June at this elevation.
Avonelle Lake suits experienced backcountry travelers and climbers who navigate steep, avalanche-prone terrain. Water access is marginal until well into summer as the basin remains snow-choked through spring. Winter and early-spring approaches demand avalanche training, beacon competency, and real-time stability assessment. Afternoon wind makes any water-based activity risky after midday; paddlers and swimmers must commit to dawn-to-mid-morning windows. Parking and facilities do not exist; self-sufficiency is mandatory. The 30-day maximum wind of 30 mph reflects severe afternoon accelerations that make exposed positions untenable.
Nearby alternatives in the Yosemite corridor include lower-elevation, easier-access lakes such as Tenaya Lake and May Lake, both served by established parking and trail infrastructure. The Cathedral Range to the west offers similar alpine lake basins with comparable avalanche terrain but more established hut systems and marked routes. Avonelle Lake is best paired with a broader Sierra high-country traverse rather than visited as a standalone destination. Winter and spring travelers should coordinate planning with SAC forecasts and evaluate the specific slope aspects feeding the basin.
