Starting Saturday, April 17 and running through April 25, all 392 of America's National Parks are free
as part of a week-long series of events and festivities known as National Parks Weeks. The point is to showcase our country's natural beauty and the freebie coincides with Earth Day on April 22.
Our National Parks are also free on Sept. 25 for Public Lands Day, and on Nov. 11 for Veterans Day. Read the full list of fee-free parks
