Horner Hot Springs is located in Alaska's Interior, a vast subarctic region where a handful of natural hot springs break through the frozen ground. This iron-rich spring holds a temperature of around 38 °C despite the harsh surrounding climate.
Insider tip — Interior Alaska around the Nowitna River watershed is one of North America's most remote wilderness regions — a vast boreal landscape of spruce forest, permafrost, and caribou migration routes accessible only by small plane or river boat. Horner Hot Springs emerges in this extraordinary subarctic wilderness, where geothermal activity beneath the Alaska Range creates iron-rich springs that have warmed indigenous Athabascan travellers and trappers in one of Earth's most isolated thermal environments.
