(CNN) -- It takes $25 per car before visitors driving into Grand Canyon National Park can enjoy its spectacular beauty, but the price of admission is going away -- for just a little while.
The National Park Service is waiving entrance fees at all of its 392 parks for a week starting Saturday as part of its annual National Park Week celebration.
So you won't have to open your wallet to visit such popular places as Yellowstone, Bryce Canyon or Yosemite.
"We are rolling out the red carpet and inviting everyone to visit a national park," Secretary of the Interior Ken Salazar said in a statement.
"Most people live within a short drive of a national park, so I encourage everyone to spend some time enjoying America's Great Outdoors," added National Park Service Director Jon Jarvis.
Earth Day (April 22) and National Junior Ranger Day (April 24) take place during the fee-free week, and there will be activities and events to mark each of the dates.
Visitors should be aware that they will still have to pay the usual fees at campgrounds and concession stands, and any fees collected by third parties.
