Yesterday I had the day to myself and had a hot tip on some hot springs. The are nestled up in the Lemhi mountains in Idaho. Trailhead is n44.8982, w113.9571.
The short but beautiful walk up to the valley takes you passed some really nice rock formations and a few waterfalls.
The hot springs themselves are at the top of a cascade, with an amazing view. Somewhere around n44.9032, w113.9318. A very pleasant way to spend an afternoon!
