Bull Buck Trailhead
Trailhead · Yosemite corridor
Bull Buck Trailhead sits at 5420 feet in the Yosemite corridor of California's Sierra Nevada. A quiet alpine gateway less crowded than valley-floor alternatives.
Wind averages 6 mph but can spike to 18 mph by afternoon, funneling down from the higher passes to the east. Morning calm typically holds until mid-day. Expect cool temperatures even in late spring; the 30-day average sits at 42 degrees Fahrenheit. Shelter from the trailhead is minimal.
Over the last 30 days, Bull Buck averaged a NoGo Score of 17.0 with temperatures holding near 42 degrees and wind at 6 mph average, though gusts reached 18 mph. The week ahead will show typical late-spring variability: watch for afternoon wind pickup and monitor crowding spikes on weekends when Highway 120 access is reliable.

About Bull Buck Trailhead
Bull Buck Trailhead sits in the high-Sierra belt between Yosemite Valley and the eastern spine of the range, accessed via Highway 120 (Tioga Pass Road). The trailhead elevation of 5420 feet places it well above the valley floor but below the passes that crown the corridor. Approach from the west via Yosemite Valley or from Lee Vining to the east; Highway 120 is the primary artery and typically opens by late April after winter maintenance. The nearest substantial resupply is Yosemite Village to the southwest; Lee Vining offers services to the east. Parking at the trailhead is limited, filling by mid-morning on weekends.
Spring and early summer dominate the visitable season at this elevation. The 30-day average temperature of 42 degrees reflects late-April conditions; expect warming into the low 50s by June and cooling again after mid-September. The 30-day average wind of 6 mph understates afternoon behavior; wind accelerates over the open terrain as solar heating strengthens, regularly reaching the 18 mph maximum recorded in the rolling window. Crowding averages 13 across the rolling 30 days, sparse compared to valley trailheads but climbing sharply the first weekends after Highway 120 opens. Snowpack lingers into early June depending on winter totals; check current conditions before committing to early-season trips.
Bull Buck suits hikers, backpackers, and climbers seeking quick access to alpine terrain without valley congestion. The user base skews experienced; casual day-hikers are less common than at lower-elevation alternatives. Parking constraints mean arriving before 8 a.m. on weekends is essential, or planning for a weekday visit when the lot remains open. Wind-sensitive activities like camping near ridges or fishing from exposed water features require morning execution; skip afternoons if you are wind-averse. The corridor sees smoke drift from late summer fires; air quality can deteriorate rapidly, especially downwind to the east.
Nearby alternatives include Cathedral Lakes Trailhead and Tenaya Lake access points, both on Highway 120 west of Bull Buck and slightly lower in elevation. Tuolumne Meadows trailheads lie further east beyond Tioga Pass. For a quieter experience at comparable elevation and better wind shelter, look to the west side of the valley near Yosemite Lake or the Merced River drainage. Bull Buck's main advantage is direct access to high passes and ridges with minimal elevation gain from the trailhead itself.
