“It’s a special responsibility to be the stewards of the memorials, battlefields, and historic sites that tell the story of the honor, courage, and sacrifice of our veterans,” said National Park Service Director Jonathan B. Jarvis. “All 413 of our parks nationwide offer the chance to reflect on what our veterans fought to protect, and may also provide opportunities for veterans and their families to find peace and healing.”

National parks and other public lands can be used to facilitate healing and reflection, physical and mental challenges, and rest and recuperation for veterans, active duty service members, and their families. Rivers of Recovery, one of the nonprofit organizations that uses national parks for this purpose, partnered with Saint Croix National Scenic Riverway to create the “Vets on the River” program, which offers multi-day trips on the park’s rivers to combat veterans suffering from physical or psychological injuries.

The National Park Service cares for many sites across the country related to the military experience, including more than 25 battlefields, 14 national cemeteries, and hundreds of memorials and monuments. Port Chicago Naval Magazine National Memorial, Manhattan Project National Historical Park, and other historic sites tell greater story of contributions, sacrifice, and consequences of conflict off the battlefield.

Active duty military members and their dependents can pick up a free military annual pass at any national park that usually charges a fee. A free lifetime pass is also available to disabled veterans. These passes provide free entrance to more than 2,000 national parks, wildlife refuges, national forests, and other federal recreational areas. More information about the passes can be found at www.nps.gov/findapark/passes.htm.

“We added extra fee-free days so that everyone has a chance to join the party,” park service Director Jonathan B. Jarvis said in a news release.

The 16 free-entry days for 2016 will be:

• Jan. 18, Martin Luther King Jr. Day
• April 16-24, National Park Week
• Aug. 25-28, National Park Service Birthday weekend
• Sept. 24, National Public Lands Day
• Nov. 11, Veterans Day

The waiver does not cover added fees such as camping, boat launches, transportation and special tours.

The park service officially turns 100 on Aug. 25. On that day in 1916, President Woodrow Wilson signed the act that created the agency “to conserve the scenery and the natural and historic objects and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for future generations.”
