National Park Week moves months

National Park Week is not happening in April in 2026. The National Park Service moved the annual celebration to Aug. 22-30 and shifted the fee-free day to Aug. 25. (nps.gov) The Interior Department announced the change on March 20, 2026, and tied it to two anniversaries: the National Park Service’s 110th birthday on Aug. 25 and the 250th anniversary of American independence in 2026. (nps.gov) The 2026 theme is “Celebrate America’s Story,” and the park service said parks nationwide will host guided tours, educational exhibits, family activities and other programs during the nine-day run. National Junior Ranger Day is set for Aug. 22. (nps.gov) For visitors, the practical change is the calendar. The main free-admission day that usually arrives during the spring National Park Week window will instead fall on Tuesday, Aug. 25, 2026, at parks that normally charge entrance fees. (nps.gov) The shift breaks with the park service’s usual pattern. The National Park Service’s annual-events page still describes National Park Week as an April observance in general, but its 2026 calendar now lists National Park Week in late August and the birthday celebration on Aug. 25. (nps.gov) The park service says there are more than 400 national parks across the country, and the August schedule is being framed around historic sites as well as natural landscapes during the nation’s semiquincentennial year. (nps.gov) That has already changed trip planning in places that use National Park Week as a spring travel cue. A USA Today local roundup published April 13 pointed Oklahoma readers to drivable alternatives, including Wichita Mountains Wildlife Refuge, for travelers who had expected the usual late-April timing. (usatoday.com) If you were waiting for the usual April kickoff, there is no late-April National Park Week in 2026. The official dates to mark now are Aug. 22 through Aug. 30, with free entry on Aug. 25 for United States residents at fee-charging parks. (nps.gov)
