Share with your 4th graders. For the 2015-16 school year, 4th graders in the United States can sign up for free admission (families included) to America's National Parks. Learn more at Every Kid in a Park. This could really save some families some money.
Looking for a National Park near you? Here is a list of National Parks by State. I've been to 3.
All of them were terrific and well worth the trip. I was a little claustrophobic in the caves, but would definitely do it again. Which parks have you been to. Any recommendations? Let me know in the comment section below.
