The Kobuk Valley National Park, in Alaska

The Kobuk Valley National Park, in Alaska, is one of the most remotely located national parks in the world. Situated on the edge of the arctic circle, this park has no roads that lead to it. The only way to reach it is by foot or sled, or by chartered air taxis. No wonder, it is one of the least visited in the National Park System. Enclosed within the 1.7-million-acres park, lies the Great Kobuk Sand Dunes, one of Alaska's true oddities, and a vestige of the immense continental glaciers that once covered much of North America.
