Want to save a couple bucks on your next visit to Shenandoah? The National Park Service just announced all park entrance fees will be waived on August 14-15. The free weekend pass is being given as an incentive to encourage more Americans to visit national parks.

“This fee-free weekend provides an opportunity for individuals and families alike to take an affordable vacation or to explore a nearby park they have never visited before,” said Secretary of the Interior Ken Salazar. “I encourage everyone to take advantage of the free admission to visit not only our greatest natural wonders but also our nation’s historic and cultural icons.”

There are 392 national parks located across the country in 49 states. A complete list by park or state is available at www.nps.gov.
