Kobuk Valley National Park
Caribou, sand dunes, the Kobuk River, Onion Portage - just some of the facets of Kobuk Valley National Park. Thousands of caribou migrate through, their tracks crisscrossing sculpted dunes. The Kobuk River is an ancient and current corridor for people and wildlife. For 9000 years, people came to Onion Portage to harvest caribou as they swam the river. Even today, that rich tradition continues.

Best Time to Visit Kobuk Valley
Best time to visit: July–September
The best time to visit Kobuk Valley National Park is July–September. Snow-free, mild weather allows fly-in access to the Great Kobuk Sand Dunes; late August–September brings the caribou migration.
In those months, average highs are 49–68°F at Great Kobuk Sand Dunes. Fewer than 10,000 people visit even in the busiest month, so crowds are rarely a concern.
Monthly averages at Great Kobuk Sand Dunes (240 ft). Climate normals (1981–2010): PRISM Group, Oregon State University.
Weather & Climate
Snow, rain, and freezing temperatures can occur any time of the year. Always travel with good quality rain gear and warm layers. Be especially careful to stay dry. Hypothermia can set in on a windy, wet day, even when it doesn't feel that cold.
