Serpentine Hot Springs is a significant geothermal resource set in a strikingly scenic valley where granite tors (chimney-like rock formations) rise to 100 feet. The hot springs were formed when surface water or spring water seeped into the ground and was heated by hot rocks. Even in the present, as water heats up, it rises to the surface and forms a pool or hot spring. The water in the Serpentine pool is between 140 and 170 degrees Fahrenheit.
Due to this constant supply of hot water, the land around the hot springs often is left bare in the winter, and has been a visiting point for Alaskan Natives for thousands of years. Serpentine Hot Springs is the most visited location within Bering Land Bridge National Preserve, and has a bunkhouse and bathhouse for tourists and locals to use year-round.
