Trailhead
June Lake, Inyo National Forest, California
Yost and Fern Lakes Trailhead is the physical starting place for Fern and Yost. 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 Yost and Fern Lakes Trailhead is published. Verify current access and temporary emergency orders still control access.
Verify current access: Use the signed Yost or Fern Lake access for the route shown on the permit. June Lake Loop; the combined permit product has two signed access arms. 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.
