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 Creek Trailhead is published. Hetch Hetchy Road access and temporary emergency orders still control access.
Hetch Hetchy Road access: Use the signed Cottonwood Creek entry from Hetch Hetchy Road. The road has controlled entrance hours; verify the trailhead turnout, legal overnight parking, wildfire conditions, and gate schedule. 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.
