Deer Lakes Trailhead
Trailhead · Yosemite corridor
Deer Lakes Trailhead sits at 9,062 feet in Yosemite's high Sierra, a jumping-off point for alpine lake access. Wind and cold dominate the calendar; spring and early summer offer the best window.
Wind averages 12 mph and gusts to 31 mph, peak in afternoon. Temperatures hold near freezing through spring; morning calm breaks by mid-day. Expect snowpack lingering into early summer and afternoon thermal wind funneling off high basins.
The 30-day average wind of 12 mph and temperatures near 31 degrees Fahrenheit reflect typical spring conditions at this elevation. Over the past month, scores have ranged from 6 to 44, with an average of 18, showing high variability as snowmelt and seasonal transitions accelerate. The week ahead will track typical late-spring patterns: colder mornings with calmer wind early, warming and wind strengthening by afternoon.

About Deer Lakes Trailhead
Deer Lakes Trailhead sits in the Yosemite corridor of California's Sierra Nevada, accessed via Highway 120 from the west. The trailhead lies at 9,062 feet elevation and serves as the launch point for backpackers and day hikers climbing to alpine lake basins in the Cathedral Range. From Yosemite Valley, the drive is roughly 2 hours via Highway 120 east and secondary forest roads. The parking area is small; arrive early on weekends or plan for midweek visits to avoid overflow.
Spring at Deer Lakes Trailhead means persistent snow, freezing nights, and afternoon wind. The 30-day average temperature of 31 degrees Fahrenheit reflects typical conditions where snow lingers into early summer. Morning hours offer calm conditions and frozen ground; by mid-afternoon, thermal wind picks up as the basin warms. The average 30-day wind of 12 mph underestimates the afternoon surge, which often reaches 20 to 31 mph. Crowding remains light at 13 visitors per recording period, partly because snow and cold deter casual hikers. Late September through October are drier, warmer, and calmer, with better trail conditions and lower wind variability.
This trailhead suits experienced backpackers and peak hikers comfortable with snow travel, stream crossings, and high-elevation exposure. Day hikers targeting alpine meadows should plan for early-morning starts and afternoon retreat before wind and cold intensify. Parking is tight; aim for Tuesday through Thursday midweek slots or first light on weekends. Bring microspikes or crampons through June; snow bridges over creeks are common and unstable. The 16 to 47 degree annual temperature range means layering is critical even in summer months.
Nearby alternatives include Tenaya Lake Trailhead to the south, which offers lower-elevation lake access with less persistent snow but more crowding. Cathedral Lakes Trailhead (accessed via the same Highway 120 corridor) provides a similar high-Sierra experience with slightly better parking. For lower-elevation Yosemite access, Highway 140 routes drivers to Valley trailheads with warmer conditions and heavier foot traffic. Climbers targeting Cathedral Range peaks typically stage here; early-season ascents require high-country route planning and avalanche awareness despite the trailhead's position outside mapped avalanche terrain.
