Mountain cradled hot springs sound extra luxurious, and they are, just not money-wise in the outdoor wonderland of Idaho. The steamy Kirkham, Burgdorf, and Silver Creek Plunge springs await. Some are part of resorts and some are backcountry springs that require access by hiking or snowmobiling in the Winter, which just adds to the adventure! If you enjoy camping, this wilderness-cation will be even more affordable (some campsites are free). The Sawtooth Wilderness, Sun Valley, and Twin Falls are all recommended spots. And if you have some extra time, venturing into nearby national parks is an option as well - Yellowstone happens to be right next door.
