Lava Hot Springs is a resort community in Southern Idaho. It is situated on the Portneuf river between the ancient lava flows of the Snake River Basin and Yellowstone.
Lava Hot Springs first came to the world's attention when Benion Hudspeth chose to cross the Caribou mountains near Fish Creek Summit (on US 30). This became the favorite route for the 49er gold rushers in their pursuit of their California treasures.
Many weary travelers stopped at the Springs before continue their journey westward.
