Kobuk Valley National Park
Updated
Overview
Kobuk Valley delivers one of Alaska's most surreal landscapes: 25 square miles of active sand dunes rising 100 feet above the Arctic Circle, sculpted by wind into shapes that belong in the Sahara. The Western Arctic caribou herd—400,000 strong—funnels through twice yearly, and you can witness it from Onion Portage, where humans have hunted this crossing for 9,000 years. The catch: there are no roads, no trails, no services. You'll fly in via bush plane from Kotzebue and navigate entirely on your own.
Time your visit for late August to catch the caribou migration's southbound leg while temperatures are still tolerable (50s-60s). Camp at Onion Portage and watch the herd swim the Kobuk River at dawn—the same crossing point used by ancient hunters, with their tools still eroding from the bluffs above.
