Active-duty military personnel and their dependents will soon be able to enter Yellowstone, Glacier and thousands of other National Park Service sites and public lands across the country. The Interior Department made the announcement today as part of an effort to thank service members and their families for the sacrifices they make.

An annual pass will be made available to members of every branch of the military free of charge beginning this Saturday, May 19th, which is Armed Forces Day. The America the Beautiful National Parks and Federal Recreation Lands Annual Pass normally costs $80 and provides access to more than 2,000 national parks, wildlife refuges and other public lands.

Military personnel can get the passes at any national park or wildlife refuge that charges an entrance fee by providing their military ID. Each family member will also be able to obtain their own pass, even if the service member is deployed or if they are traveling separately.

Senator Jon Tester, who helped work on this pass, is also working on a National Parks Freedom Pass Act, which would allow veterans and those honorably discharged lifetime park access for a one-time $10 fee.
