The National Park Service turns 100 on August 25, 2016. Did you know there are almost 400 parks in the national park system? According to the National Park Service (NPS), more than 300 million visitors collectively spent more than a trillion hours at U.S. national parks in 2015. Those numbers are expected to go up this year, given the marketing efforts around the NPS’s centennial. Even without the anniversary, foot traffic at U.S. parks has been trending upward: in recent years, the NPS has seen record attendance, which has resulted in long lines and packed campsites at some of its most popular parks.

Sound worth seeing? We agree. 24Life could not be more glad and grateful to celebrate these parks and programs that are national treasures. You can search for parks near you at and make a point of mapping out your visits to each and every one of them at some point in your life. Lifetime passes are free to anyone with a permanent disability, and just $10 for anyone over 62. If you can’t make it to a national park this summer, at least get outside somehow, somewhere, and play in celebration of a second century of caring for America’s special places in nature.
