Trailhead
Big Meadows, Kings Canyon National Park, California
JO Pass Trailhead is a source-backed overnight access point in Sequoia & Kings Canyon National Parks. Kampilo publishes only the official trail geometry and permit or camp authorization options represented in the mapped catalog.
The mapped line is a planning reference rather than a guarantee of current access. Confirm road, parking, trail, weather, fire, permit, and closure conditions with the land manager before departure.
Seasonal access
No recurring date-based closure of JO Pass Trailhead is published. Seasonal Big Meadows Road and temporary emergency orders still control access.
Seasonal Big Meadows Road: Use the signed JO Pass entry in the Big Meadows/Jennie Lakes corridor. Big Meadows Road is not plowed; verify the gate, forest-road surface, parking, snow, and fire restrictions. Cedar Grove, Mineral King, Big Meadows, and high-elevation park roads have different snow closures and operating seasons; winter access can end far below the summer trailhead.
Check current park roads, construction, gates, and permit-station instructions for the exact entry. Seasonal opening dates move with snow and repair work.
