After a day of skiing in Steamboat resort or out in the surrounding backcountry, take the car or a shuttle bus to the natural hot springs just outside Steamboat downtown. It’s a gorgeous and incredibly relaxing outdoor natural spa where you can bath in differently heated pools. Jump in between the hot pools and the cold river for some extra blood circulations. They also provide massage and you can stay over night at the springs. However, I recommend staying in downtown or by the ski resort and go up to this beautiful spot for a couple of hours in the afternoon or evening. I went there during winter and I’m sure it’s as amazing during the rest of the year.
