These animals traverse the park twice a year, and the sight of their journey across the wild landscape is nothing short of awe-inspiring.

River Adventures

The Kobuk River, snaking through the park, offers a refreshing contrast to the sandy landscapes. 

For the most pristine experience, launching from the Walker Lake area gives adventurers an unfiltered glimpse of the park’s watery arteries. 

Navigate its meandering courses either by kayak or canoe. Summer months, particularly June, bring moderate river flow rates, making it suitable even for beginners. 

But always remember: the Arctic waters can be unpredictable, so always prioritize safety.

Flightseeing Tours

Given the park’s remoteness, one of the best ways to witness its grandeur is from the air. 

Flightseeing tours can be arranged from nearby communities, providing a bird’s-eye view of the park’s diverse landscapes.

Camping under the Midnight Sun

Within Kobuk Valley, the vast, open landscapes provide a canvas for the Arctic’s prolonged daylight. 

Select a spot near the Salmon River for a serene camping backdrop. During the peak of summer, the sun barely dips below the horizon, bathing the park in a soft, persistent glow. 

This phenomenon, lasting from late June to early July, provides campers ample opportunity to explore and savor the park’s nocturnal beauty.

Historical Insights

The ancient rhythms of life still echo in places like Onion Portage. 

This archaeological site, situated on the northern banks of the Kobuk River, has witnessed human activity for over 12,000 years. 

Visit during early September, when the region sees fewer rain showers, to walk amidst relics and tools left behind by indigenous inhabitants, offering a tactile connection to ages past.

Winter Activities

As snow blankets Kobuk Valley, the park transforms into an ethereal winter wonderland. 

The areas near the Jade Mountains are particularly recommended for activities like snowmobiling and cross-country skiing. 

December offers the thickest snow covers, and for those interested in dog sledding, local guides often provide immersive experiences, with the chance to steer your own team under the shimmering Northern Lights.


Kobuk Valley National Park is a unique ecosystem for wildlife encountering. With its boreal forests, tundra and sand dunes you can explore one of the most remote national parks in the United States. 

From majestic grizzly bears to playful otters or more timid animals like foxes and hares, there are opportunities to observe some incredible creatures along your journey! 

With careful planning, patience and an open mind this amazing place will reveal its secrets to intrepid travelers who seek a once-in-a-lifetime experience!
