Interagency passes are honored nationwide at all Forest Service, National Park Service, Bureau of Land Management, Bureau of Reclamation and U.S. Fish & Wildlife Service sites that charge standard entrance fees. Interagency Annual, Interagency Senior, Interagency Access, and Interagency Military passes allow the public to enter some fee areas without additional charge. This is convenient when traveling to several areas that charge an entrance fee. These passes may be obtained by mail order through the USGS website:
Military passes must be obtained in person and are available at most federal recreation sites that charge standard entrance or amenity fees. Generally, sites that issue the Annual Pass will also issue the free US military version as well. A list of recreation sites (by state) that sell passes is available, but please first call the federal site you will be visiting to ensure that they have the pass available.
The Volunteer Pass is an Annual Pass awarded to those individuals who volunteer 250 hours at one or more recreation sites managed by five Federal agencies as a way to say "thank you!"
