For National Park Week 2021, from April 17 through April 25, national parks across the country will celebrate the natural and cultural heritage of their lands with exciting events, ranger-led activities, and even free entrance.

This year’s National Park Week is set to be one of their largest and most interactive—every day from Saturday the 17th through Sunday the 25th of April is themed to educate visitors about the history, culture, and landscape of our parks system.

National Park Week is a partnership between the National Park Service, the National Park Foundation (the official nonprofit partner to the parks), and the Department of the Interior. After starting in 1991 to honor the NPS’s 75th birthday, the week has grown to feature innovative programs and attractions to make national parks accessible to all.

“National parks are sources of inspiration, recreation, and education for everyone,” said National Park Service Deputy Director P. Daniel Smith, in an NPS press release. “During National Park Week, a wide variety of creative programs and events across the country will showcase these amazing places and encourage everyone to visit a park.”

Below is a day-by-day guide to the themes of National Park Week 2021. Events and activities are unique to each park, so the NPS encourages visitors to #FindYourPark by visiting your local park’s website and looking for their specific events for National Park Week.

Park RX Day (Fee Free Day): Saturday, April 17

The health benefits of nature and the outdoors are becoming more widely understood and acknowledged, and the country’s national parks are the perfect place to fill your outdoor prescription.

Volunteer Sunday: Sunday, April 18

Wayback Wednesday: Wednesday, April 21

Earth Day: Thursday, April 22

Visiting and supporting a national park on Earth Day isn’t just good for the Earth—it’s good for you, too!

BARK Ranger Day: Sunday, April 25

  • Know where you can go

Be sure to employ the B.A.R.K. principles so you and your canine can enjoy a safe and fun visit to a park during BARK Ranger day.
