National Parks

The National Park Service was created in 1916 when President Woodrow Wilson signed the "Organic Act" with the purpose to "conserve the scenery and the natural and historic objects and the wildlife therin and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."

Yellowstone National Park was established in 1872 as the nation's first National Park. Golden Gate National Recreation Area had the most visitors in 2014, welcoming more than 15 million people. Yosemite National Park was the most popular National Park for RV camping in 2014, with 166,744 visitors that year.

The National Parks pass covers the entrance fees to over 2,000 federal recreation sites and costs $80/year or $80/lifetime for U.S. citizens or permanent residents over 62.
