Kilo Hot Spring
Kilo Hot Spring perches at 1,609 feet elevation in the Denali Borough on Bureau of Land Management public land, a daunting 28.3 miles from the nearest road in extreme backcountry territory. This remote thermal feature represents Alaska's most isolated hot springs accessible only to experienced wilderness expeditions.
The spring emerges on mountainous terrain at elevation with boreal forest and tundra mixed landscape. The higher elevation setting offers expansive views across interior Alaska backcountry, with sparse vegetation and exposed terrain increasing with elevation. Water emerges hot against a landscape of intense cold—average annual temperature reaches just 25°F (-3.9°C)—creating dramatic thermal contrast in remote wilderness.
Kilo Hot Spring lies in the Central Yukon Field Office territory within Alaska's extensive geothermal zone. The spring's name reflects its location relative to old trail markers or historical survey points. This remote feature has seen minimal development or visitation, remaining relatively unknown in the broader context of Alaska's thermal resources.
Access requires multi-day backcountry expedition with expert navigation skills. The 28.3-mile distance from roads demands complete self-sufficiency. No established trail exists; route-finding through tundra and forest is necessary. Winter may offer easier travel on snow; summer requires bushwhacking. Only experienced backcountry travelers should attempt this extremely remote location. Bring detailed topographic maps.
