Kobuk Valley: Alaska's Hidden Park Redefines Adventure

Kobuk Valley National Park spans 1.7 million acres in Arctic Alaska, encircled by the Baird and Waring mountain ranges with the Kobuk River winding through its heart. Visitors explore the Great Kobuk Sand Dunes, the largest active dunes in the Arctic at 25 square miles, alongside Little Kobuk and Hunt River dunes. The park lies on the migration path of the Western Arctic caribou herd, spotlighted at Onion Portage, a National Historic Landmark used for 9,000 years.
