About Trailhead Group Campground
Trailhead Group Campground occupies a high-elevation site in the Yosemite corridor at 10,171 feet, accessed via Highway 120 from the west or US-395 from the east. The campground sits inland from the open Sierra crest, sheltered by lodgepole and whitebark pine. Primary access is Highway 120, the main trans-Sierra route; drive time from Lee Vining is roughly 90 minutes, from the Bay Area 4 to 5 hours. The site is managed as a group reservation area, making it quieter than heavily advertised roadside campgrounds but requiring advance booking.
High-elevation weather dominates the site's character. The rolling 30-day average temperature of 24 degrees Fahrenheit reflects typical spring conditions at this elevation; nighttime freezes occur regularly into late spring, and early snow returns by late summer. Wind averages 14 mph over 30 days but accelerates to 30 mph by afternoon as pressure systems push air over the Sierra crest. Crowding averages just 12 visitors, a function of group-only access and limited site capacity. The site opens after Highway 120 clears, typically late spring, and remains accessible through early fall before early storms force closure.
Trailhead Group Campground suits groups planning backcountry access or multi-day car camping away from Valley traffic. Visitors come for proximity to high-Sierra trailheads, not roadside amenities. Water is seasonal; confirm availability before booking. Afternoon wind makes early morning the window for kayaking or paddling nearby waters; skip afternoon if water access is central to your plan. Parking is limited by design. Smoke from Sierra fires in late summer can degrade visibility; check current air quality before committing to visual activities.
The site sits 10 to 15 minutes from other Highway 120 corridor options, including Tenaya Lake and lower-elevation alternatives near Crane Flat. For groups seeking solitude over crowds, Trailhead's group reservation model and modest popularity (0.3 base index) offer genuine relief compared to first-come sites downstream. Winter closure runs roughly November through May, aligning with Highway 120 seasonal closure; timing a visit around the annual opening window captures stable conditions as snowpack recedes.
