Kobuk Valley National Park · Gates of the Arctic NP · National Wild & Scenic River

The northernmost major salmon river in North America and Alaska’s premier sheefish fishery. The Kobuk drains the Brooks Range and flows through Gates of the Arctic and Kobuk Valley National Parks to Kotzebue Sound. Sheefish ("Connie") run up the Kobuk each July and grow to 50-plus pounds, drawing fly-in anglers from Kotzebue and Ambler. The river also holds chum salmon, Dolly Varden, and grayling, and is one of the classic multi-day wilderness floats in Alaska — remote, grizzly country with no road access and very few people.
