Rockslides Trailhead
Trailhead · Yosemite corridor
Rockslides Trailhead sits at 4045 feet in the Yosemite corridor's high-Sierra transition zone. A moderate-elevation staging point with steadier conditions than the valley floor below.
Wind averages 7 mph but funnels unpredictably through the ridgeline saddle by afternoon. Morning calm is reliable; afternoons turn turbulent. Temperature swings from 7 degrees in winter to 62 degrees in summer.
Over the last 30 days, the average NoGo Score here was 16.0 with wind averaging 7 mph and temperature at 41 degrees. The week ahead will show whether warming trends push afternoon gusts above the seasonal max of 17 mph. Crowding averages 13 visitors per sample window, so weekday mornings remain uncrowded relative to Highway 120 corridor peaks.

About Rockslides Trailhead
Rockslides Trailhead lies at 4045 feet in the Yosemite corridor, accessed from the Highway 120 corridor near the Sierra crest transition. It serves as a staging point for backcountry and day-use routes into high-alpine drainage systems. The trailhead sits roughly 90 minutes east of the Central Valley via Highway 120. Parking is limited and fills early on clear weekends. Vehicle access depends on Highway 120 closure dates; the corridor typically opens by late spring.
This elevation experiences three distinct seasonal regimes. Winter (December to February) brings sustained cold; overnight lows dip to 7 degrees and afternoon highs rarely exceed 40 degrees. Spring (March to May) is volatile; the current 30-day average sits at 41 degrees with wind ranging from calm mornings to 17 mph afternoon gusts. Summer (June to September) brings the warmest conditions; high temps climb to 62 degrees but wind remains consistent at 7 mph average. Fall (October to November) reverses the pattern; cooling returns rapidly by late September.
Rockslides Trailhead suits hikers, backpackers, and scramblers seeking high-Sierra routes without the Yosemite Valley car-camping crowds. The base popularity is low (0.4 on NoGo's scale), meaning you'll encounter far fewer people than at Tenaya or Cathedral Lakes. Plan morning departures to avoid afternoon wind; the 30-day max wind of 17 mph can turn exposed ridges sketchy. Bring layering for temperature swings. Parking pressure is highest Friday afternoon through Sunday morning; weekday mornings are reliably open.
Nearby alternatives include Tenaya Trailhead (lower, more crowded) and backcountry routes off Highway 89 to the north. Rockslides pairs well with multi-day trips since its isolation means few day-hikers conflict with overnight permit holders. The 4045-foot elevation places it above Valley floor weather but below true high-alpine extremes, making it a refuge when either lower or higher zones are out of condition.
