Trailhead
Buttermilk Country, Inyo National Forest, California
Upper Buttermilk Trailhead is the physical starting place for Upper Buttermilk. Kampilo maps only source-supported named overnight areas connected to the official Forest Service trail network.
Camp markers identify general dispersed areas rather than tent pads or guaranteed openings. Confirm the current road, trail, weather, fire, permit, and legal-site conditions before departure.
Seasonal access
No recurring date-based closure of Upper Buttermilk Trailhead is published. High-clearance access and temporary emergency orders still control access.
High-clearance access: Primitive road-end parking. Rugged high-clearance seasonal dirt road. Check current closures, weather, and vehicle requirements before leaving pavement. High Sierra approaches can be snowbound well into summer, and several roads, shuttles, and remote spurs operate only seasonally. Desert and foothill entries may remain physically reachable in winter but can become unsafe in storms, heat, or after washouts.
Check the exact county, highway, Forest Service road, gate, and shuttle status immediately before departure; a wilderness permit does not guarantee vehicle access.
