If you've ever wanted to go to the Grand Canyon, this week is the time to do it.

In honor of the National Park Service's 100th anniversary, the U.S. agency is waiving admission fees for all national parks and monuments during National Park Week– April 16th through April 24th.

Though camping fees will still apply, 410 different parks are opening their doors to accept visitors from near and far for the celebration–not only wilderness areas, but historical sites like Gettysburg, Jamestown and the Wright Brothers Monument, and homes of presidents, like Franklin D. Roosevelt and Harry Truman.

"We have an amazing variety of special events taking place during the centennial," said National Park Service Director Jonathan B. Jarvis. "Some commemorate our first hundred years, but many others look to the future, to the next 100 years, and will help connect with and create the next generation of park visitors and supporters. It is through them that America's lands and stories will be preserved and passed on to future generations."

With National Junior Ranger Day kicking off the event on Saturday, activities have been planned throughout the week to entertain kids and adults alike. Visit FindYourPark.com to learn more about National Park Week activities throughout the country.

If you aren't able to travel to a park during the coming week, other free admission days this year will include August 25 through August 28, to mark the National Park Service Birthday; September 24, for National Public Lands Day; and November 11, to honor Veterans Day.
