The National Park Service will be celebrating its 99th birthday today. There won’t be cake, but there will be free entry to any of the 408 national parks across the country.
While most of these parks are usually free every day of the year, over 100 parks (including well known spots like the Grand Canyon and Yellowstone) usually charge an entrance fee.
Here are all the parks that will be going fee-free just for today’s special birthday celebration. (Any national park not on this list is free all year round.) Find a park near you:
