National Park Week Set for Aug. 22-30, With Free Entry on Aug. 25
The National Park Service has scheduled National Park Week for Aug. 22-30, 2026, and will waive entrance fees for U.S. citizens and residents on Aug. 25.
The free-entry date will coincide with the National Park Service’s 110th birthday. The announcement, issued July 23, gives travelers a date to consider when planning summer visits, while also leaving park-specific reservation and access rules in place.
What the 2026 policy includes
National Park Week will run for nine days, from Saturday, Aug. 22, through Sunday, Aug. 30. The separate free-entrance day will be Tuesday, Aug. 25.
Under the 2026 policy, the waived entrance fees apply to U.S. citizens and residents. The National Park Service has not said that every service, activity or amenity at a park will be free. The policy concerns entrance fees.
The National Park Service operates more than 400 national park sites nationwide. A March bulletin from the U.S. Department of the Interior cites 433 national parks in describing the scale of the system and outlines summer access plans at Arches, Glacier, Rocky Mountain and Yosemite national parks.
That national scope means the Aug. 25 policy could affect travel planning and visitor activity across parks with very different operating conditions. The Interior’s summer plans pair expanded access with park-specific safety and management measures rather than presenting a single access rule for every location.
Free entry does not mean unrestricted access
Visitors should not assume that the fee waiver removes all requirements for Aug. 25. The National Park Service says reservations, timed-entry systems and other park-specific rules may still apply.
Individual parks may also impose local capacity or safety controls. Those measures can shape whether and when visitors are able to enter a particular site, even when the entrance fee itself is waived.
The announcement therefore creates a potential savings opportunity for eligible visitors, but it does not guarantee a reservation-free visit or unrestricted access throughout the national park system. Travelers will still need to check the requirements for the park they plan to visit.
The agency has promoted park-specific access plans for high-visitation parks during summer 2026. The Interior bulletin specifically identifies Arches, Glacier, Rocky Mountain and Yosemite as parks with access and safety planning. The source material does not provide a single nationwide visitation forecast for National Park Week or the Aug. 25 free-entry date.
Why the dates matter for travelers
National Park Week falls during the summer travel season, when decisions about entrance fees, reservations and capacity can affect itineraries and expected visitor activity. The Aug. 25 date may be especially relevant to U.S. citizens and residents comparing the cost and timing of a park trip.
For park operators, the week and birthday-related free-entry day provide a scheduled period that must be managed across more than 400 sites. The Interior Department’s stated approach indicates that access expansion will be accompanied by local safety and management measures at parks facing high visitation.
Those details are important for travelers who interpret “free entry” as a promise of open access. Entrance fees and admission availability are separate questions. A visitor may qualify for the fee waiver and still need a reservation, a timed-entry permit or compliance with a local capacity rule.
What happens next
The National Park Service’s next known step is implementation of the scheduled Aug. 22-30 National Park Week and the Aug. 25 fee waiver. Individual parks are expected to continue communicating their own access plans and requirements as the 2026 summer season approaches.
For now, the confirmed dates are Aug. 22-30 for National Park Week and Aug. 25 for free entrance for U.S. citizens and residents. Visitors should verify local rules before traveling, because the national announcement does not replace park-specific reservation, timed-entry, capacity or safety requirements.
