Fly to Great Kobuk Sand Dunes, Kobuk Valley National Park, Alaska, USA
This remote part of the Arctic Circle has no maintained trails, so you’ll be route-finding in the Alaskan bush. Boreal forest gives way to tundra along the Kobuk River, where you’ll find 25 square miles of sand dunes. Getting there requires a bush plane.
