National Park Week

National Park Week is the National Park Service's annual weeklong celebration, running August 22 to 30 in 2026 under the theme "Celebrate America's Story" for the nation's 250th anniversary. Parks across the country add ranger programs, Junior Ranger activities, and events through the week. Entrance fees are waived for U.S. citizens and residents on August 25, the Park Service's 110th birthday, which falls inside the week; other fees still apply.
