Boiling River: Hidden Gem of Yellowstone National Park (+2024 Info)

Boiling River: Hidden Gem of Yellowstone National Park (+2024 Info)

Boiling River in Yellowstone is one of the less known places of America’s oldest National Park. Tucked in the far north corner of the park it’s a true hidden gem of Yellowstone NP.

We had never heard of the Boiling River when planning our trip to Yellowstone National Park and it was a complete coincidence that we discovered it (read about it below).

We mentioned this discovery among our suggestions of the best things to do in Yellowstone with kids and after a while, the emails and the questions started coming in… So many of our readers told me that our blog inspired them to visit Boiling River in Yellowstone and that it became one of the highlights of their trip.

This inspired me to write this guide for visiting Boiling River in Yellowstone. What is the Boiling River? Where to find it? How hot is the Boiling River? What to expect… You can find all the answers to these questions and practical information below… But first, as promised, our story of how we discovered the Boiling River in the first place.

How we found out about the Boiling River in Yellowstone

The evening before we would arrive in Yellowstone, we were having dinner at a cozy hamburger restaurant in Jackson, WY. It was the peak summer season and the place was crowded. We were seated at a long table where you brush elbows with strangers and inevitably end up listening to other people’s conversations.

It didn’t take long for people around us to start asking where we were from. After all, we were the only non-English-speaking family at the restaurant…

We ended up chatting with a family from Montana. They had just spent a few days in Yellowstone and were willingly sharing their experiences. Most places they mentioned were, of course, familiar to us; after all, we have done so much research for our trip to Yellowstone in advance. But then we asked them what were their absolute favorite places and they mentioned Lamar Valley and Boiling River.

Boiling what?

We had read tens of blog posts, travel guides, and consulted the official website of Yellowstone National Park in search of the best experiences in Yellowstone when planning our Yellowstone trip itinerary. We researched and booked our Yellowstone accommodation a year in advance… Yet we hadn’t seen Boiling River mentioned anywhere.

Not once had we read anything about one of the coolest places in Yellowstone…

So it was thanks to the friendly strangers at a restaurant that we found out about Boiling River in Yellowstone National Park. This post is just my way of giving back because some places are just too good to keep to yourself. Read on!

What is Boiling River

Boiling River in Yellowstone is a sort of natural hot tub where a large hot spring enters the cold waters of Gardner mountain river. The cold and hot water mingle and makes the water temperature comfortable enough to bathe in.

Boiling River is one of the few legal thermal soaking areas in Yellowstone (the other popular place is Firehole River, but it’s much better known and therefore much busier).

It’s a wonderful place to start or end your day in Yellowstone. What can be better than a soak in a warm river after a long day exploring the highlights of the park… If you have more time, you can even pack a picnic and make a whole day trip of it.

How to get to the Boiling River + Map

Boiling River is located next to the main road 89, between Mammoth Hot Springs and the North Entrance of Yellowstone, just at the border between Wyoming and Montana (see the map below for the precise location).

It’s about 5 minutes drive from Mammoth, 1h from Canyon Village, and about 1,5h drive from the Old Faithful area.

There is a bathroom and a small parking area at the start of the short trail leading to the hot spring. If you are coming from the south, it’s on the right side of the road just before crossing Gardner river; and if you are coming from the north, it’s on your left just after you cross the river.

Keep in mind that Boiling River parking area is very small, so it quickly fills up. Many people park next to the road, but in general, it shouldn’t be a problem to find a parking spot as people come and go all the time. We visited at the end of July and while we were not alone, it wasn’t overly busy at the hot spring either.

Hiking to the Boiling River

The Boiling River bathing area is located about half a mile (0,8km) upstream from the car park.

A flat dirt path is an easy scenic walk along the river and can’t even be called a hike; it shouldn’t take you more than 10 minutes. Most people walk here in their flip-flops.

Depending on the outside temperature, you can see the large steam clouds from far. Where the path intersects with the river, you’ll find a small area with a wooden fence and signs indicating where it’s safe to swim. This is also the only place where you should swim!!!

How hot is the Boiling River and can you swim in it?

Boiling River is not called ‘boiling’ for nothing! Discharge of hot water from an underground source flows out of the ground and is then mixed with the cold waters of Gardner river, turning a small piece of a wild mountain river into a sheltered relaxing hot tub in the most spectacular setting. The water temperatures can vary from around 100 to 140 degrees (38-54°C), so you have to look for a perfect temperature for you.

This area of the Gardner river is just deep enough to sit in and is somewhat sheltered, making it comfortable and safe to bathe. Still, you should be cautious as to where exactly you sit as water temperatures change all the time. Obey the signs and don’t go too close to the source! You really don’t want to risk getting burned.

It takes some time to find a place where the temperature feels just right for you. Our kids loved looking for a spot where they could feel the hot water on one side and ice-cold water on the other side of their body at the same time. You can sit or lay in the river here, but you can’t actually swim – it’s not deep enough.

When you find that perfect mix of hot and cold water, it’s a wonderful place to relax. We have been to many hot springs all over the world, but Boiling River beats them all. It’s a place like no other, a unique wonder of nature.

I made a short video, it will give you an idea of what bathing in Boiling River looks like… Take a look!

 

Is it safe to swim in Boiling River in Yellowstone?

Water temperature. As long as you are careful not to go too close to the stream, you can find perfect water temperatures that are comfortable and enjoyable for bathing.

Disease-causing microorganisms. Thermal waters contain organisms that can cause serious skin rashes, infections, etc. There are signs at the Boiling River that inform you about all possible dangers and warn to avoid submerging your head underwater or inhaling thermal steam.

You have to remember that it’s a natural phenomenon, conditions change all the time, and your body can react differently than somebody else’s. So be careful, and in case you experience any symptoms, get out of the water immediately and seek medical assistance.

We never experienced any issues and hundreds of people bathe at the Boiling River every day, so I don’t think you have to worry much. Just be aware of the potential dangers and understand that you’re bathing at your own risk.

Stream. The designated bathing area is quite sheltered and when the area is open, it means that the stream here normally isn’t dangerous. Once again, it’s nature and the situation can change quickly.

Boiling River with kids

Boiling River can easily be visited with kids. The walk to get there is short and easy, the water warm and not deep, and every child will love it!

As you can see in the video above, we took our boys bathing in the Boiling River and they had the time of their lives. Playing in water, building river dams… We spent over an hour in the water and they didn’t want to leave…

Of course, you have to be careful, just like anywhere else. If you are planning to bathe here with toddlers, it might be wise to look for a very secluded place with calm water and use swim armbands.

 

Is Boiling River open right now?

Important update 2024: Boiling River in Yellowstone is currently CLOSED due to substantial damage to the area after the floods of 2022. At the moment of the last update of this article, the official website of Yellowstone still doesn’t give any indication if the swimming area will reopen or when. For the up-to-date situation check the official site. The last time I checked, swimming was allowed at Firehole Swim Area, so it could be a nice alternative to Boiling River.

Boiling River is usually open from late summer till the end of winter. It is closed to the public in spring and early summer when the river water is too high and too wild due to the melting snow.

The Boiling River Trail can also be too muddy making the area inaccessible before mid-summer. Therefore, Boiling River is usually closed from mid-March till mid-July.

In general, you should expect Boiling River to be open from mid-July, but it varies from year to year. That being said, Boiling River is also usually open in autumn and in winter… Can you imagine a better hot tub in the winter months?!

TIP: If you are planning on visiting Boiling River, it’s best to check current conditions on the official website of National Park Services.

Practical information for visiting Boiling River in Yellowstone

  • Boiling River swimming area is open during the day till it gets dark (it used to be open 10 am to 6 pm, but it’s not clear if there are any official opening hours at the moment and the official website doesn’t list them either.
  • Car parking is very small and gets filled quickly, so you may have to wait a while till a spot frees up. Many people park next to the road as well.
  • Bathing suits are required. The only place where you can change clothes is in a single vault toilet at the car parking.
  • It’s forbidden to drink or eat in the river. You may bring a picnic, but no alcohol.
  • There are no lifeguards and swimming in the Boiling River is at your own risk.
  • Water shoes are recommended. We had flip-flops and our kids were wearing crocs and I ended up chasing one of their shoes down the stream in the river. I can tell you, it’s not fun and can actually be quite dangerous. It’s much safer to wear water shoes.
  • The area has no shade, so if you come in summer, make sure you have and use sun protection. UV t-shirts and sun hats are a good idea if you plan on staying in the water for longer than 5 minutes.

So bummed the info about Boiling River closure wasnt posted earlier - I read all about it on your great blogs and planned out our trip to include it (planned earlier in 2022 and 2023) but now see that it is closed permanently. The floods changed the entire course of the river. I put a note about this on your other itinerary page too - hope it helps someone! (and maybe delete this whole page??)

Hi Elizabeth, we can not delete this page exactly for this reason - some people might still be looking for this information. Plus, the official website of Yellowstone still doesn't say that Boiling River is permanently closed. It now only says " Currently, swimming is not possible at Boiling River because of the impacts to the river from the 2022 floods".

Your itinerary has been so helpful. Just want to let you know we went to go to the Boiling River and it is closed. In fact, the ranger explained that it NO LONGER EXISTS. The whole area was washed out and destroyed in last years floods and heavy rains. HWY 89 is also closed to traffic. It’s July 2023.

Thank you for your kind feedback, Ashley. Glad to help. As for Boiling River, yes, sadly, the area has been closed for quite a while now. The official website doesn't clearly say what they are planning to do with that area in the future beyond this short statement: "Currently, swimming is not possible at Boiling River because of the impacts to the river from the 2022 floods". Let's hope they will be able to reopen it one day, but indeed, it doesn't look like it will be any time soon. I'll leave this link to the official site once more for those looking for the latest updates on the situation.

Loved your site was very informational. We are staying in Park Island for our 4 day trip to Yellowstone. Said 45 min drive to West Entrance. This does not count travel dates. Would we be able to see everything you mentioned for 4 day trip without a problem. We do want to do some short hikes if any suggestions. Will leave early in morning and spend the day till evening. Packing our lunch. Any other suggestions?

Hi Bevely, if you plan well and start your days early, I think you can see most of the park. Just focus on different areas each day to limit the driving. Once again, start VERY early. From everything I see, it will be very busy in Yellowstone this summer. So try to beat the crowds to get into the park in the morning and head to the most popular place of that day's itinerary first thing in the morning. For more practical tips, please see our tips for visiting Yellowstone in summer. As for the hikes, we have quite a lot of easy hike suggestions in our Yellowstone with kids article. Check it out for some inspiration! One of our personal favorites was Uncle Tom's Trail - steep stairs down into Yellowstone canyon.

Early in your article, you mention you heard about the Boiling River in a "cozy hamburger joint in Jackson, WY". We are headed there after Yellowstone & love a good hamburger! Can you share your favorite hamburger joints in Yellowstone as well as Jackson? Thank you!!!!

Hi Kat, I had to dig deep into my memory and also the map to find it. I think it was Liberty Burger in Jackson. In Yellowstone, there are many restaurants, but they are all run by the National Park. The food is ok, but it's not any special and all the restaurants are so big and busy... We had hamburgers at the Canyon Village and it was ok. We weren't that impressed with the Old Faithful Inn dining room either (we had lunch and breakfast there). Hope this helps you a bit.

I have planned our Yellowstone / Grand Tetons / Badlands / Mt Rushmore road trip for June 2020. And I mean, I researched it to from A to Z - National park websites, travel forums, people's blogs, discussion posts... countless days and nights spent planning and mapping everything. And nowhere, NOWHERE did I see a mention of Boiling River! Crazy! Also, I am originally from Latvia (hello, neighbor!), living in the U.S. now and traveling with my 2 little boys (and husband drags along too:-) ), and keeping a blog about it, so I am very happy I have found yours!

Hi Liene, it's indeed a somewhat lesser-known place, but still busy... I see that you'll be traveling in June and it's usually closed in that period (see the post for more info). If that's the case and you want to try swimming in a hot river, you can try the Firehole river swimming area instead (if it's open). However, that area is even more busy, there's pretty much no space to park and the whole roadside is basically filled with parked cars... So if you're going there, you'll probably have to get there very early in the morning or maybe late in the afternoon... Enjoy your trip!
