National Park Service Birthday

NPS Photo

Come join our birthday celebration on August 25! The National Park Service was created on August 25, 1916, to "preserve unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations." Over the hundred plus years, we've grown into more than 400 national parks and many programs that reach communities around the country—and even the world!

Our birthday is part of National Park Week this year so come celebrate all week! Join the birthday fun on social media using #NPSBirthday, #NPS110, and #NationalParkWeek.
