Just came across this, it’s certainly a nice benefit offered to those who have served our country.
A free lifetime pass to our public lands is available for veterans of the U.S. Armed Services and Gold Star Families, and a free annual Military Pass is available for current U.S. military members and their dependents.
The passes provide free access to more than 2,000 federal recreation areas, including national parks and wildlife refuges. Interior is proud to offer these passes to demonstrate our immense gratitude for those who currently serve and who have served our country.
