I recall nude swimming at Boiling River late in the evening years ago when I visited the park as part of a 3300 mile bike trip around the northwest. I was in my teens and we spent a couple of nights camping in the area and visited the hot springs, where, after dark, a few folks dared to bare, mostly a college-aged crowd but a few young teens like myself (I didn’t dare to bare it all though 🙂
Found it!
It’s called the “Boiling River”, and information is here:

Additionally, there is some swimming allowed in parts of the Firehole River, along the scenic drive.
Update, just got back from Yellowstone, and candidly, the Boiling River is possibly the most underrated attraction in Yellowstone. The Boiling River itself is actually the Gardiner River, along a trail called “Boiling River.” The trailhead is in a parking lot just as one crosses the WY/MT border, about a mile north of Mammoth Hot Springs. From the parking lot, expect a walk of about 3/4 of mile, whereupon, in the middle of summer at least, you will find a bunch of people swimming.
The Boiling River area gets its warmth from an outlet of Mammoth Hot Springs. There is a little pool enclosed by rocks that is a bit hotter than a hot tub. (Based on my experience, I’d guess the water to be about 104 to 106 degrees F – just slightly hotter than I like in the hot tub.) The water spills beyond a semi-circle of rocks, however, mixing with the otherwise colder water of the Gardiner River. The result is a very definite pattern of warm and cold in the River that is just amazing.
Two things to keep in mind:
This is a national park, and so conservation is high on their minds. No soaps, no horseplay, basic “behave” kind of stuff. (No nudity, for example, is on the signs, but that isn’t really a conservation measure.) There is a sign at the front that warns visitors that this is one of those places that is getting “loved to death.”
The current is incredibly strong. My nearly 11 year-old daughter was nearly swept away at one point. Grant you, there are enough people to catch you, but the rocks make it hard to stand, and the current is just incredibly pervasive. All in all, it actually makes for a very enjoyable experience.
Highly, highly recommended.
