Kobuk Valley National Park

About Kobuk Valley National Park

Kobuk Valley National Park covers 1.7 million acres entirely above the Arctic Circle in Alaska’s western Brooks Range. The park has no roads and no maintained trails. The Great Kobuk Sand Dunes – 25 square miles of active sand dunes deposited by glaciers, rivers, and Arctic winds over the past 150,000 years – are the largest active arctic dune field in North America and the park’s signature landmark. The park sits in the migratory path of the Western Arctic Caribou herd, which currently numbers roughly 400,000 animals. Brown and black bears, wolves, Dall sheep, moose, and muskoxen share the valley with salmon and sheefish in the Kobuk River drainage, and golden eagles, bald eagles, and a broad range of resident and migratory bird species use the corridor seasonally. The Iñupiat and Athabascan peoples of northwest Alaska have lived in the Kobuk Valley region for over 9,000 years. Onion Portage, within the park boundary on the Kobuk River, is one of the most significant archaeological sites in the Arctic and has yielded evidence of nearly continuous human use spanning thousands of years. The contemporary villages along the Kobuk River – Ambler, Shungnak, Kobuk, Kiana – continue traditions of fishing, hunting, and seasonal travel that predate the park’s establishment by millennia.

Our Guided Kobuk Valley Trips

We offer two scheduled trips that include Kobuk Valley each summer. Both also visit neighboring Gates of the Arctic National Park. Our Noatak River and Great Kobuk Sand Dunes Combination is a 12-day Level 2 multisport expedition that pairs a Noatak River float with a hiking visit to the Great Kobuk Sand Dunes. The trip begins in Fairbanks with a night at Pike’s Waterfront Lodge (orientation dinner and breakfast), then continues by Wright Air Service and Brooks Range Aviation into the upper Noatak River for the rafting segment, transits to Kobuk Valley for the dunes hike, and concludes with a flight back to Anchorage from Kotzebue on the final day. Air partners include Wright Air Service, Brooks Range Aviation, Golden Eagle Outfitters, and Alaska Airlines. Our Western Arctic National Parks Basecamp is a 7-day Level 2 hiking trip structured as a more accessible introduction to the region. The itinerary begins and ends in Anchorage with a night at our partner hotel (orientation dinner and breakfast). From Anchorage, the group flies commercially to Kotzebue and continues by bush charter to a basecamp, from which the group hikes into both Kobuk Valley and Gates of the Arctic. Air partners include Alaska Airlines and Golden Eagle Outfitters.

How to Get to Kobuk Valley & When to Visit

Kobuk Valley has no roads and no maintained trails. Access routes are by scheduled commercial flight to Kotzebue or Fairbanks, followed by bush charter to the park. The exact sequence depends on which of our trips you join – the Noatak/Kobuk Combination routes through Fairbanks, while the Western Arctic Basecamp routes through Anchorage and Kotzebue. The Kobuk Valley season runs from June through mid-August. The Arctic summer brings long daylight – 24-hour sun north of the Arctic Circle through most of June and July – but weather can swing widely. June and early July offer the most consistent travel weather; August brings cooler temperatures and the start of fall color across the tundra. For most travelers, the practical question is not when to visit Kobuk Valley but how, since 10,000 to 15,000 people reach the park in a typical year. Our two scheduled trips handle the logistics.
