Maple Grove Hot Springs, in Thatcher, Idaho, offers iron-rich thermal water around 38°C. Tucked away in the Idaho countryside, the spring is enjoyed in an open-air pool or as wild bathing.
Insider tip — Maple Grove Hot Springs occupies a quiet valley in southeastern Idaho near the Bear River Range, with iron-rich thermal water flowing into a series of developed soaking pools. The landscape is open sagebrush terrain typical of the Great Basin, contrasting with the warmth of the geothermal water. Spring and fall bring wildflower blooms and migrating birds to the surrounding wetlands fed by overflow.
