WASHINGTON, D.C. — The Department of the Interior has announced that National Park Week 2026 will take place Aug. 22–30, marking both the 110th anniversary of the National Park Service and the nation’s 250th anniversary of independence.

The weeklong celebration will feature hundreds of programs, family activities and patriotic events across the country under the theme “Celebrate America’s Story.” National parks nationwide are expected to host guided tours, educational exhibits and hands-on activities designed to connect visitors with the country’s history and landscapes.

A fee-free day is scheduled for Aug. 25, coinciding with the National Park Service’s birthday, allowing visitors to enter parks that typically charge admission at no cost.

The celebration will begin Aug. 22 with National Junior Ranger Day, offering youth the chance to participate in interactive activities and earn Junior Ranger badges.

Officials say the 2026 event carries added significance as part of the nationwide commemoration of America’s 250th anniversary, with parks hosting special programs and exhibits tied to the country’s founding throughout the year.

The National Park Service oversees more than 400 sites across the country, preserving historic landmarks and natural areas that reflect the nation’s heritage.
