What You Should Know Before Going to Kanuti Hot Springs
Kanuti Hot Springs is a fully wild and undeveloped geothermal site inside the Kanuti National Wildlife Refuge. Travelers who love this kind of raw, untouched wilderness often also explore Serpentine Hot Springs, another remote geothermal area surrounded by dramatic tundra scenery. There are no roads leading to the springs and no services or structures of any kind.
The hot water emerges close to the Kanuti River with temperatures around 57–60 °C (135–140 °F). The springs are very hot, so visitors usually look for areas where hot and cold water blend into a comfortable soaking temperature.
Visitors must be entirely self-sufficient, bringing all food, water, gear and navigation tools. There is no cell service, no shops and no emergency support anywhere nearby. Seasonal conditions can make the terrain muddy, wet or challenging, and the refuge is home to bears, moose and other wildlife.
How to Get to Kanuti Hot Springs
Reaching Kanuti Hot Springs is part of the adventure. The springs are located within the Kanuti National Wildlife Refuge, positioned between the refuge boundary and the Caribou Mountains. Access is not easy, and because there are no marked trails, carrying a Bettles B-2 topographical map is highly recommended — and often essential.
The best time to visit is during the warmer months, when you can make the approximately 14-mile journey down the Kanuti River. Most visitors begin their float at the Dalton Highway crossing at Mile 103, following the river southwest toward the springs. If you’re traveling through the Fairbanks region, another classic backcountry soaking trip is the hike to Tolovana Hot Springs, known for its remote cabins and long trail across the hills.
If you choose to hike out, the topographic map will guide you along the tundra ridgeline high above the treeline, continuing through the open wilderness before descending back toward the road.
In winter, it is also possible to snow-ski or snowshoe to the springs, but deep snow and harsh conditions make it a route suitable only for those experienced with Arctic travel.
Kanuti Hot Springs is accessible — but only to those who come well-prepared, well-equipped, and ready for true Alaskan wilderness.
Best Time to Visit Kanuti Hot Springs
Kanuti Hot Springs can be visited year-round, but the experience varies greatly with the seasons. The best time to visit is during summer and early fall, when floating the Kanuti River is easiest and overall access is safer. Days are long, temperatures are mild and the tundra landscape is vibrant.
In winter, the area becomes a silent expanse of snow and ice. Reaching the springs by skis or snowshoes is possible, but deep snow, severe cold and limited daylight make the journey suitable only for experienced winter travelers. The rising steam from the hot water creates a surreal and beautiful winter atmosphere.
Spring and late fall are shoulder seasons, often marked by mud, melting snow, high water levels and unpredictable weather — conditions that can complicate travel significantly.
For most visitors, summer provides the safest and most accessible experience, especially if you’re planning to travel by river. It’s also the season when many travelers visit other geothermal sites featured in our roundup of the best Alaska hot springs.
