Kobuk Valley National Park
Kobuk Valley National Park, AK
Arctic Alaska
One of the least-visited national parks in the country, where sand dunes rise improbably above the Arctic Circle and vast herds of caribou ford the Kobuk River twice a year.
Kobuk Valley protects one of the most surprising landscapes in Alaska: sand dunes, real ones, rising in golden waves above the Arctic Circle. The Great Kobuk Sand Dunes cover many square miles along the south side of the Kobuk River, left behind by ancient glaciers that ground rock into sand, then swept into dunes by the wind. To stand on warm, rippled sand with Arctic tundra and boreal forest all around is one of the strangest and most memorable sights in the north.
The park's other great drama is the caribou. Twice a year, the vast Western Arctic caribou herd, hundreds of thousands of animals, moves across this country on migration, and many of them ford the Kobuk River right through the park, a crossing used by people and predators for thousands of years. With no roads, trails, or buildings anywhere inside it, Kobuk Valley is among the least-visited national parks in the country, a place of pure wilderness reached only by bush plane.

Worth Knowing

Sand dunes in the Arctic
The Great Kobuk Sand Dunes are the park's signature wonder, an expanse of active dunes that feels wildly out of place so far north. They were born when Ice Age glaciers pulverized rock into sand, which rivers and wind then gathered into dunes along the Kobuk, and they remain active today, shifting in the Arctic wind. On a warm summer day the sand can grow surprisingly hot, framed by cool tundra and distant mountains.
There is nothing built here to guide a visit; travelers land by small plane on a nearby river bar or gravel strip and walk in. The reward is a landscape almost no one else has seen in person, dunes in the Arctic, silent and empty under the vast northern sky.
The river and the caribou
The Kobuk River is the lifeline of the park, a broad, gentle river winding through tundra and forest that offers the main way to travel here by raft or canoe. Along its banks lie places used by people for thousands of years, tied above all to the caribou that pass through.
Each year the great Western Arctic herd migrates across this land, and one of its traditional river crossings lies within the park at Onion Portage, a spot of deep importance to the region's Native people and a scene of extraordinary wildlife when the animals are moving. Witnessing even part of that migration is a rare privilege in one of the emptiest corners of the country.
