The park hours change throughout the year. The park hours are generally changed when daylight savings time changes. Summer hours are 8am-8pm. Winter hours are 8am-6pm. Many websites have incorrect park hours. I work in Muir Woods, I know that the only website with accurate up to date information about park hours is the official National Park Service website.
