Trailhead
Death Valley National Park, California
Cottonwood–Marble Route Access is a source-backed overnight access point in Death Valley National Park. 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 Cottonwood–Marble Route Access is published. Mandatory-permit route access and temporary emergency orders still control access.
Mandatory-permit route access: Use the official Cottonwood–Marble start and obtain the route-specific permit. Confirm road, parking, water-cache, and shuttle logistics. Backcountry zones do not share a recurring annual closure season, but extreme heat, flash floods, mud, and washouts frequently close individual roads. High-elevation roads can also be snowbound.
Check the park's live road map and backcountry-road page on the departure day; road status can change rapidly after storms.
