Tamarack Flat Trailhead
Trailhead · Yosemite corridor
Tamarack Flat Trailhead sits at 7073 feet in Yosemite's high Sierra corridor, a modest staging point for backcountry access. Wind and exposure define the place.
Wind runs steady and can spike to 23 mph in the afternoon; morning calm is the exception. Temperatures average 40 degrees Fahrenheit across the 30-day window. The exposed parking area offers no shelter; afternoon visitors face direct gusts funneling off ridge terrain.
The 30-day average wind of 7 mph masks afternoon surges and cold baseline temperatures near 40 degrees. Crowding remains light at an average of 13 people; the trailhead is rarely busy. The week ahead will follow typical spring volatility, with wind and temperature swings tied to storm passage.

About Tamarack Flat Trailhead
Tamarack Flat Trailhead sits on the high plateau of Yosemite's Sierra Nevada corridor, accessed via Highway 120 from the west. The trailhead launches hikers into the high country south and east of Tuolumne Meadows, connecting to larger backcountry networks. The nearest gateway is Lee Vining to the east or Groveland to the west; Highway 120 is the only practical approach. Parking is limited and unimproved; arrive early to secure a spot, especially on weekends after Highway 120 opens for the season.
Spring and early summer bring the highest wind, with 30-day gusts reaching 23 mph and an average of 7 mph across rolling weeks. Temperatures average 40 degrees Fahrenheit in the rolling 30-day window and can drop to 26 degrees overnight or earlier in the season. Summer stabilizes conditions but brings afternoon thunderstorms; late summer and early fall offer the calmest window. Winter closure of Highway 120 ends access entirely. Crowding averages 13 people and stays low year-round; this is not a destination trailhead.
Tamarack Flat Trailhead suits backpackers pursuing multi-day routes into the high Sierra, not day hikers seeking views or quick ascents. Expect exposed, windswept terrain with minimal shelter or services. Experienced users plan for afternoon wind by hiking early, carrying extra layers, and avoiding the exposed parking area during peak gusts. Water sources are absent at the trailhead itself; carry sufficient capacity or plan to cache water upstream.
Nearby alternatives include Cathedral Lakes Trailhead and Glen Aulin High Sierra Camp, both accessed via Highway 120. Tamarack Flat Trailhead differs in its isolation and backcountry character; it draws fewer visitors and offers no ranger station, water, or facilities. For day hikes with guaranteed parking and services, Tenaya Lake or the Tuolumne Meadows complex are superior choices. Tamarack Flat Trailhead is a launching point for committed backpackers, not a public recreation area.
