So, if you do a little googling, you’ll find that Montana has quite a few hot springs. Some you have to pay for, like my personal favorite, Norris Hot Springs, and some you have to find, like my new natural favorite, Potosi. Potosi is a natural hot spring in the woods, filled by the hot water bubbling up from the ground.
My friends and I ventured out there from a camping site we were staying at, it was about a mile walk in the woods, nothing too treacherous. We headed out around 9, since it’s way too hot during the day to hang out at a hot spring and because we wanted to be there at night- way cooler literally and figuratively. Someone had built a nice little fence/deck thing around it, which gave us a place to hang our towels and such. No one was there when we got there, so we had it for about 20 minutes to ourselves, and then a couple of people showed up and we stayed for another 40. When we left, we must have passed at least a dozen people heading there, so we were lucky to miss what was about to be a crowded soak.
If you’re looking for a mini adventure while your here, try this one out with some friends. It was pretty awesome.
