US National Parks
Sixty-three areas of the United States carry the full 'National Park' designation — a list that runs from the coral reefs of American Samoa to the arctic valleys of Gates of the Arctic, and from the 0.09-square-mile Gateway Arch to Wrangell–St. Elias, larger than Switzerland.
Marking a park here means you've set foot in it. The map shows real congressional boundaries; the Learn tabs cover the geology, ecology, and history that make each park worth the drive.
