That means it will cost zilch to teeter over the edge of the Grand Canyon, gaze at the towering Tetons, or simply take a dip at one of the 50 national parks that have beaches. Although food, guided tours, and camping still cost extra cash, this could save families a pretty penny. Big-name parks, such as Yellowstone and the Grand Canyon, charge $25 per car or $12 per visitor who enters by foot, bicycle, ski, or any other non-motorized vehicle.
The only downside we see here: The great outdoors will probably be jam-packed. More than 2.75 million people visit the country’s national parks each year, and June, July, and August regularly see the most traffic. Couple that with free entrance and prime weekend travel dates before school starts up again, and, well, you might be standing on tip-toes to catch a glimpse of Old Faithful.
