Iron Mountain Hot Springs’ water is sourced from three naturally-occurring springs—Hobo, Gamba and Redstone. The three natural hot springs emerge onto the Iron Mountain Hot Springs property with average water temperatures ranging from 105 to 108°F. The water is collected in the pump house, which is located behind the café, and then cooled to different temperatures before it’s distributed to the 16 soaking pools. The temperatures in the soaking pools range from 98 to 108°.
