The payoff of a long, hot soak in the Kilo Hot Springs is a great reward after your strenuous wilderness hike. Located “somewhere” in the vast Alaskan interior, Kilo Hot Springs is frequently listed in Alaska’s Top 10 Hot Springs.
Hot Springs Pools
Kilo Hot Springs is remotely located in a broad and breathtaking valley on the northern side of the Ray Mountains along the Kanuti Kilolitna River. There is a large section of the river with many natural pools of varying temperatures, though the average temperatures are approximately 122°F.
The length of the hot springs is about 211 feet and rests at an elevation of 1604 feet above sea level. Your body will be grateful for the hot spring that flows north from a crystal clear stream at the end of your 40-mile trek through the mountains.
There are no facilities near Kilo Hot Springs and camping is allowed anywhere within 100 feet of the hot springs shoreline. Make sure you pack in everything you might need for a few days’ outing as the nearest road is 40 miles away.
Kilo Hot Springs can be accessed in two different ways; a 40-mile hike or a private flight that lands visitors within 5 miles of the stream location. Most visitors choose to hike because of cost restrictions.
This hike is one of the most strenuous and remote of all Alaskan hot springs adventures and all who conquer it are definitely due bragging rights for their journey. A typical journey looks something like paddling 20 miles down the Yukon River to discover a ridge where your packraft can be tucked away for a steep climb into the high country of the Ray Mountains.
Then a 40-mile trek by foot through treeless tundra will bring you to the Kilo Hot Springs where you will be more than ready for a long, hot soak. Those choosing to fly can rent a plane that will land them on a firm ridge about a 5-mile hike from the springs.
