America the Beautiful Pass

The America the Beautiful Pass (also known as the Interagency Pass) series comprises annual or lifetime passes that grant the holder entrance to more than 2,000 federally protected areas including national parks, national monuments, and other protected areas managed by six federal agencies: the National Park Service, the Forest Service, the Fish and Wildlife Service, the Bureau of Land Management, the Bureau of Reclamation, and the Army Corps of Engineers. At per-vehicle fee areas, the pass entitles the holder and all passengers in a non-commercial vehicle to admission. At per-person fee areas, the pass entitles the holder and up to three additional adults to admission (children under 16 are always admitted free). The pass was created by the Federal Lands Recreation Enhancement Act and authorized by Congress in December 2004, which is Division J, Title VIII of the Consolidated Appropriations Act, 2005, Public Law 108–447, 118 Stat. 2809, an omnibus appropriations act. Passes are available at all National Park Service sites that charge entrance fees as well as online through the United States Geological Survey online store. The passes have been described as one of the best deals in recreation.
