Trailhead
Angeles National Forest, California
Red Box Trailhead is a source-backed overnight access point in San Gabriel 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 Red Box Trailhead is published. Red Box junction parking and temporary emergency orders still control access.
Red Box junction parking: Use the signed Red Box parking at Angeles Crest Highway/Redbox Road and verify Adventure Pass, gate, and fire restrictions. San Gabriel routes do not share a single annual closure season. Wildfire recovery, storm damage, snow, heat, and forest orders can close individual roads, trails, or areas.
Check Angeles National Forest alerts and the exact route before departure; an expired closure order is not evidence that a trail has reopened.
