Our National Parks takes you on a journey through the four seasons and the many faces of our scenic national parks. Experience an array of lands and waters from Alaska's glacier-clad Denali to the turquoise coves and coral reefs of the Virgin Islands; from the fire of Hawaii Volcanoes to the coolness of Kentucky's Mammoth Cave; from the moonscapes of South Dakota's Badlands to the granite shores of Maine's Acadia. With award-winning filmmaker Wolfgang Bayer you get an in-depth tour of nine of the most popular national parks plus a seasonal overview of many more.
