If you have a fourth grader, you're in luck. The National Park System is offering a new Every Kid in a Park pass this year.
The program, which started September 1 and goes through this school year, allows fourth grade students to obtain a special pass good for them and their families to visit any federally managed land/water site. This includes more than 2,000 national parks, forests, wildlife refuges and marine sanctuaries. For this program, the pass allows in the fourth grader and three adults, or a car full of people for drive-in parks. This all leads up to the National Park Service's 100th birthday in 2016.
Here's where to get the Every Kid in a Park pass and more information.
