The Department of the Interior today announced that National Park Week – an annual weeklong celebration of America’s national parks – will run from April 17 to April 25. National Park Week encourages the public to explore the vast network of our national parks, sacred sites, and historical landmarks, as well as our shared heritage contained within them.

To kick off National Park Week, every national park will have a free admission day on Saturday, April 17. The public is asked to recreate responsibly when visiting parks, including following rules requiring masks when physical distancing cannot be maintained, or to explore parks virtually through a variety of engaging online activities. Visit nps.gov/npweek or nationalparkweek.org for more virtual programming.

The National Park Service invites everyone to participate in a Twitter chat preview of National Park Week on April 16 at 1 p.m. Join the conversation and share favorite memories, tips and stories about national parks using the hashtag #NationalParkWeek.

“The National Park Foundation and our park partners celebrate the full diversity of our parks. They come in all shapes and sizes. They are urban and rural, natural and manmade. They each have their own, unique story, perspective and experience to share with all of us that, when taken together, really tell the American story,” said National Park Foundation President and CEO Will Shafroth. “And each of us has an important role to play in helping to preserve and protect these special places.”

The 2021 National Park Week theme days include:
