The power of America’s national parks is undeniable. Millions have packed up the family to hike through impossibly lush forests, to gaze upon towering cliffs and deep-plunging canyons, to witness the breathtaking arcs of natural history, and, most of all, to share moments of wonder amid the protected treasures of this land. National Parks Adventure is acclaimed filmmaker Greg MacGillivray’s most visually ambitious giant-screen film to date—a film that offers not only a sweeping overview of the national parks’ history, but is equal parts adrenaline-pumping odyssey and soulful reflection on what the wilderness means to us all.
