Overview / About

Kobuk Valley National Park, located in northwestern Alaska above the Arctic Circle, is one of America’s most remote and least visited national parks. Spanning 1.75 million acres, it protects a vast wilderness of sand dunes, boreal forests, and river valleys surrounded by the rugged Baird and Waring Mountains.

Established in 1980, the park is best known for the Great Kobuk Sand Dunes, massive Arctic dunes sculpted by wind and ice, and the seasonal migration of hundreds of thousands of caribou that cross the Kobuk River each year. With no roads, trails, or visitor centers inside the park, Kobuk Valley offers a rare chance to experience pure wilderness and solitude.
