On your way to see Old Faithful, you may want to take the 2-mile long Firehole Canyon Drive to the “heated” Firehole swimming hole in the Firehole River.
You will drive past the 40-foot waterfall of Firehole Falls.

Just a little farther up the road, you’ll see the Firehole swimming area. The hot springs of Yellowstone National Park feed into the river and heat the chilly water to a comfortable temperature. There is another swimming area called Boiling River near the north entrance of the park.
Please read the regulations and find additional information about the Firehole and Boiling Springs swimming areas at Swim and Soak prior to your visit. Most of the park’s hot springs are extremely hot and soaking in them is prohibited. These are the only two places where swimming is allowed.
On our last few visits, we have been at Yellowstone in May and June. The Firehole has been closed to swimming because the water level was too high. It’s a nice place to take a short break when you are out exploring the park.

You can access the area by this staircase when it’s open.

Swimming the river in the summer
When the water levels drop in the summer, you can drift the river beginning near the cliffs. Large signs warn you about the risks of swimming here so use common sense.
I took the following two pictures in July 1998. Note how the trees in these pictures show the effects of the fire of 1988. Compare them to the pictures above, taken in 2011 and 2018.
In nature, lightning causes fires that help thin overgrowth and release the seeds of certain types of pine. The photos in the beginning of this post show how a healthy forest is regrowing in Yellowstone.

This is what the Firehole swimming hole typically looks like on a warm summer day. I have many fond memories of swimming here with my family over the years. It is a special spot!

Looks so fun and refreshing Siobhan. I’m thinking it might be a bit chilly at the moment 😊
Yes, it’s at about 7,500 feet in elevation. The water temperature can be in the 80’s.
