It is time for National Park Week again. Starting on Saturday, April 20th, all national parks will be hosting special events to encourage people to visit the park system. The week-long celebration of the U.S. park system begins with free admission day on April 20th. Every day of National Park Week will be themed. This year's celebrations include:

  • April 20: National Junior Ranger Day
  • April 21: Military & Veterans Recognition Day
  • April 22: Earth Day
  • April 23: Transportation Tuesday
  • April 24: Wild Wednesday
  • April 25: Throwback Thursday
  • April 26: Friendship Friday
  • April 27: BARK Ranger Day
  • April 28: Park Rx Day

Visitors are encouraged to share their experiences on social media for the event. If you post on Twitter and follow it with the #FindYourPark hashtag, Twitter will insert a special ranger emoji on your post.

The national park system only has five days this year that offer free admission, including:

  • Jan 21, Martin Luther King Jr. Day
  • April 20, start of National Park Week
  • August 25, for the birthday of National Park Service
  • September 28, National Public Lands Day
  • November 11, Veteran's Day

These free dates present an excellent opportunity to visit a park that you have never enjoyed before or revisit an old favorite. The national park system has been updating and renovating many of their parks to include new and exciting features that are appealing to people of all ages.

For those who enjoy visiting the national parks throughout the year, year-long passes will be available at all parks. A year-long pass is a good investment as the United States has one of the most diverse and extensive national park systems in the world.
