North Fork Koyukuk

NORTH FORK KOYUKUK RIVER BACKPACKING – 7 days
A pristine mountain lake is the starting point for this Alaska hiking trip next to the North Fork of the Koyukuk River in the central Brooks Range.

BackpackingWe will pack through a beautiful pass on the southern flank of the Continental Divide on our way to the headwaters of the Koyukuk River in Gates of the Arctic National Park. Originating above timberline, the North Fork of the Koyukuk River winds through dramatic mountain scenery. The headwaters, while too shallow for floating, are home to arctic grayling. Hanging glaciers and brooding peaks tower above us as we explore downriver.

We’ll hike the base of Mt. Doonerak, the tallest mountain in the central Brooks Range. Our hike ends at the true “Gates of the Arctic,” Frigid Crags and Boreal Mountain. You have the option of ending your trip at this point, or continuing on to Bettles by way of the river.
