The National Park Service officially turns 100 this Thursday, August 25, and in celebration of this, the Park Service is offering free admission to all 124 of its properties that normally charge a fee. That means if you live within a reasonable distance of Yellowstone, or the Grand Canyon, or Fort McHenry, or any other NPS park listed here, take some time out of your weekend and go see them. Normally, they’re well worth paying for (and it’s worth pointing out that those entrance fees pay for the parks to remain open), but free is always good, right? The free birthday weekend runs from Thursday, August 25 through Sunday, August 28.
It’s also worth remembering that fourth graders get into National Parks for free all year.
