The National Park Service just turned 100 years old! Celebrate the start of our second century by visiting a park in 2017. During ten days of the year, all National Park Service sites that charge an entrance fee will offer free admission to everyone.
Our national parks are our country’s biggest -- and best -- playground. Stretching across more than 84 million acres, and found in every state, our parks give us a chance to hike, explore, learn and play.
When you visit a National Park on one of the free days and send a note or picture to email@example.com, they will compile them and share online.
More information can be found on the National Park Service website.
