Trailhead
Hetch Hetchy, Yosemite National Park, California
Hetch Hetchy 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 Hetch Hetchy Trailhead is published. Entrance-hour limits and temporary emergency orders still control access.
Entrance-hour limits: Use the designated overnight lot near the Hetch Hetchy backpackers campground. The entrance road is controlled by daily gate hours, even though permitted overnight parking is allowed. 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.
