Trailhead
Hetch Hetchy Road, Yosemite National Park, California
Base Line Camp Road Trailhead is a source-backed overnight access point in Yosemite 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 Base Line Camp Road Trailhead is published. Hetch Hetchy Road access and temporary emergency orders still control access.
Hetch Hetchy Road access: Use the signed Base Line Camp Road entry from the Hetch Hetchy corridor. Verify Hetch Hetchy entrance hours, the access-road gate, legal overnight parking, and current fire or storm closures. Tioga Road and Glacier Point Road usually close for snow from about November into late May or June. Valley, Wawona, and Hetch Hetchy access use different road and gate rules.
Road opening and closing dates are condition-driven. Check park conditions and the selected trailhead parking page immediately before travel.
