Clark Fork Trailhead
Trailhead · Yosemite corridor
Clark Fork Trailhead sits at 6,493 feet in the Yosemite corridor, accessing the high Sierra drainage above the Clark Fork. A moderate-elevation gateway to alpine meadow and creek terrain.
Wind averages 9 mph but funnels strongly in afternoon hours as thermal circulation builds. Morning calm persists until mid-day. Temperatures sit near freezing through spring, warming into the 40s by early summer. Crowding remains light compared to Yosemite Valley trailheads.
Over the past 30 days, the 30-day average wind of 9 mph reflects typical spring conditions, with temperatures holding near 32 degrees Fahrenheit and crowding sparse at 14 on the relative scale. The trend chart below shows the week ahead against the prior 30-day baseline; expect continued morning stability and afternoon wind gusts as seasonal patterns intensify.

About Clark Fork Trailhead
Clark Fork Trailhead lies 6,493 feet up in the high Sierra, accessed via Highway 120 (Tioga Road) approaching Yosemite's eastern entrance. The trailhead serves the Clark Fork drainage, a granite-carved system with seasonal creeks, meadow clearings, and views into the Cathedral Range. Drive time from Lee Vining is roughly 90 minutes; from Tuolumne Meadows, 45 minutes west. Parking is limited but rarely fills except on holiday weekends in summer. The trailhead marks the start of several routes ranging from day hikes to backcountry traverses.
Spring and early summer dominate the visitation window. The 30-day average temperature of 32 degrees reflects April snowpack; by June, highs climb into the 50s and 60s. Average wind runs 9 mph with afternoon gusts to 23 mph typical on clear days. Winter closure of Highway 120 isolates the trailhead from December through April; confirm road status before driving. Crowding averages 14 relative units, far lighter than Yosemite Valley lots. Snow lingers at this elevation into June; confirm melt patterns before committing to high-Sierra passes or creek crossings.
Clark Fork Trailhead suits hikers comfortable at elevation who plan early starts to avoid afternoon wind. The sparse crowds and moderate access difficulty attract experienced day-hikers and backpackers seeking solitude over marketed views. Bring layers; morning temps near freezing flip to afternoon sun exposure quickly. Wind is predictable (calm before 10 a.m., building steadily after noon) so schedule accordingly. Water is abundant but requires treatment. The site works best for those pairing it with nearby Tenaya Lake or Cathedral Lakes traverses rather than as a standalone destination.
Nearby Cathedral Lakes Trailhead (west via Highway 120, lower crowding, similar wind patterns) and Tenaya Lake access points offer variation in distance and elevation gain. Clark Fork suits visitors who want higher-altitude terrain and fewer other hikers than the more famous Yosemite Valley and Tuolumne Meadows routes. The Clark Fork drainage connects to larger Sierra Crest networks for experienced mountaineers, but day-hike access is straightforward and well-marked.
