To celebrate the 110th anniversary of the National Park Service and National Park Week, the United States will waive entrance fees for all 433 national park sites on August 25, 2026. This waiver is specifically for U.S. residents and does not include concessionaire fees or specific permits.

During the week-long celebration, which runs from August 22 to August 30, various parks are scheduled to host themed events, such as “WatchWildlifeWednesday.”

The fee waiver comes as the National Park Service manages several ongoing challenges, including overcrowding, aging infrastructure with a maintenance backlog exceeding $23 billion, and environmental concerns related to climate change and land-use policies.
