Trailhead
Trinity Alps Wilderness, Shasta-Trinity National Forest, California
Long Canyon Trailhead is a source-backed overnight access point in Trinity Alps Wilderness. 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 Long Canyon Trailhead is published. Long Canyon access · seasonal mountain road and temporary emergency orders still control access.
Long Canyon access · seasonal mountain road: Use the signed Long Canyon Trailhead for the Deer Creek and Siligo high-country routes. Verify the final road, snow, washouts, parking, and current closures. Trinity Alps Wilderness has no published recurring closure season, but high-country snow can persist into summer and remote forest roads can be blocked by snow, washouts, wildfire, or storm damage.
Check Shasta-Trinity alerts and the exact signed trailhead road immediately before travel; a self-issued wilderness permit does not guarantee road or trail access.
