There are a plethora of teeny tiny towns here in Idaho. Like, super tiny. In fact, Idaho might be home to one of the smallest towns in the entire country. The town featured here has a population of a whopping three people. Yes … three. This makes it by far the tiniest town in the Gem State. However, this tiny town isn’t all that unknown. Located in eastern Idaho, Warm River is a wildly popular spot to visit because of the area’s immense natural beauty. The fact that so few people live here only adds to the magic of this incredible town!

Warm River is, in fact, a town ... despite having only three permanent residents according to the last U.S. Census. It's located on the very eastern edge of Idaho, just shy of the Wyoming border and about nine miles northeast of Ashton.
