Did you know that the United States is home to 394 national parks, with at least one park in every state except Delaware, according to the U.S. National Park Service? With so much open space to enjoy within a short drive of home, who needs air travel? If you're lucky enough to live near some of the more well-known of these parks, don't miss Old Faithful at Yellowstone National Park, or the exotic stone arches at Arches National Park in Utah. Those in other parts of the country may be surprised to see the wonders at lesser-known parks like South Dakota's Badlands or Oregon's Crater Lake.
These parks not only provide miles of hiking trails and spectacular views, they also offer a chance to get up close and personal with caribou, bears and other wildlife. Best of all, an annual America the Beautiful Pass costs less than $100, and provides access to every national park in the country for a full year.
