About National Park Service Founders Day
National Park Service Founders Day is observed on 25 August each year in the United States, marking the anniversary of the founding of the National Park Service (NPS) in 1916. On that date, President Woodrow Wilson signed the National Park Service Organic Act into law, establishing a federal agency dedicated to protecting and managing the nation’s national parks and monuments for the benefit of present and future generations. The day is celebrated across all of America’s national parks with special programmes, ranger-led activities, and often free admission.
What is National Park Service Founders Day?
National Park Service Founders Day, also known as NPS Founders Day or the NPS Birthday, is an annual celebration of the creation of the federal agency responsible for preserving and managing the United States’ most iconic natural and cultural landscapes. The National Park Service oversees more than 400 sites across the country, ranging from Yellowstone and the Grand Canyon to the Statue of Liberty and the Gettysburg battlefield.
On Founders Day, the NPS typically offers free admission to all national parks that charge an entry fee, making it one of the most popular days in the national parks calendar. Special ranger-led programmes, guided hikes, educational activities, and community events are held at parks across the country, from Alaska to Florida and Hawaii to Maine.
The day serves both as a celebration of the NPS’s achievements and as a call to action for conservation. Visitors are encouraged to engage with the natural world, learn about environmental stewardship, and reflect on the importance of protecting wild places for future generations.
When is National Park Service Founders Day?
National Park Service Founders Day is observed on 25 August each year, the anniversary of President Wilson’s signing of the NPS Organic Act on 25 August 1916. The NPS typically announces its free entry programme in advance, and specific events at individual parks can be found on the NPS website closer to the date.
Why National Park Service Founders Day Matters
The creation of the National Park Service in 1916 represented a landmark moment in the history of conservation. Before the NPS was established, the nation’s parks and monuments were managed inconsistently by a patchwork of federal agencies, including the Forest Service and the War Department. The Organic Act unified this management under a single agency with a clear mission: to preserve natural and cultural resources while making them accessible to the public.
That dual mandate, preservation and access, remains at the heart of the NPS’s work more than a century later. The agency manages sites that are not only ecologically significant but also culturally and historically essential to the American story. National parks protect biodiversity, safeguard watersheds, preserve archaeological sites, and maintain habitats for species that exist nowhere else on Earth.
Founders Day provides an opportunity to reflect on how much has been achieved since 1916, when only 35 national parks and monuments existed, and to consider the challenges ahead. Climate change, habitat fragmentation, and increasing visitor pressure all pose real threats to the parks the NPS stewards. The observance encourages both celebration and renewed commitment to conservation.
The NPS also contributes significantly to the US economy: national parks generate billions of dollars in visitor spending each year, supporting hundreds of thousands of jobs in gateway communities across the country.
How to Get Involved
There are many ways to participate in National Park Service Founders Day:
- Visit a national park. Many national parks waive their entry fees on Founders Day. Check the NPS website for confirmation of the free entry programme for the current year. Whether it is a drive through Shenandoah or a walk along the rim of the Grand Canyon, visiting a park on this day is the most direct way to celebrate.
- Attend a ranger-led programme. National parks run a wide variety of guided activities on Founders Day, including nature walks, campfire talks, junior ranger activities for children, and astronomy sessions at dark-sky parks.
- Volunteer. Many parks organise volunteer clean-up days and trail maintenance events around the Founders Day period. Contact your nearest national park to find out how to participate.
- Donate to the National Park Foundation. The National Park Foundation is the official charity partner of the NPS and accepts donations that directly support conservation programmes in America’s national parks.
- Share on social media. Post photographs and memories from your national park visits using hashtags #NPSFoundersDay and #FindYourPark to help raise awareness of these irreplaceable places.
History of National Park Service Founders Day
The origins of National Park Service Founders Day trace directly to a piece of legislation signed by President Woodrow Wilson on 25 August 1916. The National Park Service Organic Act established a new bureau within the Department of the Interior, tasked with overseeing the growing collection of federally protected lands that had accumulated since Congress designated Yellowstone as the nation’s first national park in 1872.
The driving force behind the creation of the NPS was Stephen Mather, a wealthy businessman from Chicago who came to Washington in January 1915 as a special assistant to the Secretary of the Interior. Mather was alarmed by the inconsistent management of the parks and threw himself into lobbying for a dedicated federal agency. Working alongside his assistant, Horace Albright, Mather built a broad coalition of support that included railway companies, environmental groups such as the Sierra Club, journalists, and members of Congress.
When the Organic Act was signed, Mather became the first Director of the National Park Service, a role he held until 1929. Under his leadership, the NPS grew rapidly, acquiring new parks and developing the infrastructure: roads, lodges, and visitor facilities, that made the parks accessible to the general public. Mather is widely credited with establishing the character of the national park experience that millions of visitors enjoy today.
The NPS has grown substantially since 1916. From an initial portfolio of 35 parks and monuments, the system has expanded to more than 400 sites covering over 85 million acres across all 50 states, the District of Columbia, and several US territories. These sites collectively welcome more than 300 million visitors per year.
The annual Founders Day celebration was formalised as the NPS’s official birthday observance, with free entry days and special events becoming a consistent feature of the August calendar. The NPS uses the anniversary to launch new conservation initiatives, announce park improvements, and engage communities in discussions about the future of the national park system.
