Kobuk Valley Overview

Kobuk Valley National Park, located in northwestern Alaska above the Arctic Circle, is one of the United States‘ most remote and least visited national parks. Encompassing over 1.7 million acres (about 6,880 square kilometers), the park is a stunning representation of Arctic wilderness, untouched by roads or permanent human structures. Established in 1980 as part of the Alaska National Interest Lands Conservation Act, Kobuk Valley National Park protects an incredible landscape of sand dunes, rivers, and mountains, offering a unique glimpse into the Arctic’s natural beauty and ecological diversity.

The park’s most notable feature is the Great Kobuk Sand Dunes, often described as a desert in the Arctic. These vast dunes, some reaching heights of up to 100 feet (30 meters), were formed over thousands of years by windblown glacial silt and are a striking contrast to the typical Arctic landscape. The Kobuk River, a vital lifeline of the park, meanders through this diverse terrain, supporting a rich array of wildlife, including caribou, grizzly bears, wolves, and a variety of migratory birds.

One of the most extraordinary natural events occurring in Kobuk Valley is the annual migration of the Western Arctic Caribou Herd. Each year, over 200,000 caribou cross the Kobuk River, migrating through the sand dunes in one of the world’s greatest wildlife spectacles. This migration has been a critical part of the subsistence lifestyle for the Indigenous peoples of the region for thousands of years.

Kobuk Valley National Park’s isolation and harsh climate make access challenging, typically requiring a flight on a small bush plane. However, for those who venture into this untouched wilderness, the park offers unparalleled opportunities for adventure, solitude, and the chance to witness the Arctic’s raw beauty. The park’s vast landscapes, significant archaeological sites, and the incredible phenomenon of the caribou migration make Kobuk Valley a unique and precious part of America’s natural heritage.
