The Best Places To Retire Boise was #5 last year. Luckily all our other Idaho cities thrived and one of them even made the top 100. While Boise may not have been mentioned a few other Idaho cities did get the shoutout they deserved. Hopefully this time next year even more Idaho cities will be recognized. Meridian was #72 on the list, Idaho Falls was at #74. and Twin Falls is #111 for the best cities in America to retire in.
