Idaho Falls Magazine's 2014 Rexburg issue opens its list of ten things you never knew about Rexburg and Madison County with the hot springs. Green Canyon and Heise, it says, are both open to the public year round with natural mineral water for swimming and soaking, and both are within a half hour of town.
It sits on the list alongside the Menan Buttes, the Porter Park carousel and the county fair, which is about the right company.
