Big Oak Flat Road turnout: Use the signed Old Big Oak Flat Road entry and its designated turnout. Do not block service access; verify rockfall, wildfire, and road-work notices before leaving a vehicle overnight. 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.
