As we ended our day in Yellowstone, our entire family whined when my wife recommended we change into swimming suits and head to Firehole. However, it turned into the trip highlight for everyone.
We arrived at the swim area at around 7 pm, and there were only two other groups there. If you go down the stairs, you are led to a nice, calmer part of the river. The rocks are slick, but it is a nice place to hang out with families.
If you swing left halfway down the path, you can break off the main trail, traverse some rocks and get to a swift, warm part of the river. My teens (all good swimmers), swam across the river, traversed some rocks on the opposing side, and jumped in at the mouth of the little slot canyon and floated down (quickly) about 50 feet - just to climb out and do it again. The parents did too - just not as frequently.
We were very concerned one would hit his/her head when we jumped into the rapids, but we had no accidents. The speed of the river through that section demanded some decent swim skills.
We were joined by another group that had a more difficult time making the trip across (not really sure if it was swim skill or nerves - it wasn't quite "extreme sport" so I couldn't tell).
You can float all the way through the minor S-shaped canyon to the shallow, slow area mentioned at the beginning. (The first time we actually swam against the current to get to the beginning of the ride from the slow area - that took some effort.)
There are two bathrooms along the road to change into suits.
It was a great way to catch the sunset at the end of the day in the park. The crowds had died down, the water was warm, and the experience was energizing.
