The National Park Service is waiving all park entrance fees on Saturday for National Public Lands Day.
This is one of five entrance-fee free days this year.
The National Park System has more than 85 million acres of land and includes national parks, national historical parks, national monuments, national recreation areas, national battlefields, and national seashores. There is at least one national park site in every U.S. state.
The entrance fee-free day does not cover amenity or user fees for camping, boat launches, transportation, or special tours.
There is one more National Park free entrance day this year on Veterans Day, Monday, November 11.
An annual pass is available for $80. It can be used to gain unlimited entrance to more than 2000 recreation areas across the United States.
The National Park Service was created on August 25, 1916, when President Woodrow Wilson signed the National Park Service Act.
