National Park Week takes place April 21 through April 29, 2012. Admission is free at all 397 national parks during the celebration.
Looking for something fun, free, and fantastic to do with family and friends? Head out to America’s national parks where millions of stars light up the dark night sky, deer and antelope (and a few other critters!) play on the wide open range, and history is an unbelievable experience, not an exam.
