Filmed over the course of more than six years at some of nature's most spectacular locales — from Acadia to Yosemite, Yellowstone to the Grand Canyon, the Everglades of Florida to the Gates of the Arctic in Alaska — The National Parks: America's Best Idea is nonetheless a story of people: people from every conceivable background — rich and poor; famous and unknown; soldiers and scientists; natives and newcomers; idealists, artists and entrepreneurs; people who were willing to devote themselves to saving some precious portion of the land they loved, and in doing so reminded their fellow citizens of the full meaning of democracy. It is a story full of struggle and conflict, high ideals and crass opportunism, stirring adventure and enduring inspiration - set against the most breathtaking backdrops imaginable.

This 12-hour, six-part series is the story of an idea as uniquely American as the Declaration of Independence and just as radical: that the most special places in the nation should be preserved not for royalty or the rich but for everyone.
