My hike to hot river in Hveragerdi


We went to this river at the beginning of October, when the weather was still warm. When we left Reykjavík, about 7 o’clock in the evening, it wasn’t too cold and it wasn’t even raining. Unfortunately, after arriving in Hveragerdi it started to rain lightly, so trips in Iceland can never be planned perfectly.

We arrived at the parking lot at about 8 o’clock in the evening. Our equipment was only drinks, baguettes from the Olís petrol station, swimwear and towels. We quickly hit the trail as we knew it would get dark soon.

Finding the trail was easy, from the parking lot there is one main road into the mountains that you stay on until you reach the river, which you can tell by the steaming hot water.

At this time of year the trail was a bit muddy in some places and our white converse sneakers were definitely not the ideal footwear. Around 9 o’clock we finally saw the wooden walkway that goes around the river.

We met only two other tourists at the river, who left the river after about 20 minutes, and we were left completely alone. We found a suitable place where the temperature was about 36 degrees and even though the river was not very deep, it was enough for us to lie down and enjoy relaxing in the pleasant water.

Hot river in Hveragerdi

It got completely dark during our stay in the river, so we started back around 11 in the evening, because the batteries in our mobiles were not fully charged and we were worried about having enough power to light our mobiles on the way back.

It turned out to be a good idea because the way back was really dark and we might have gotten lost without our cell phones. Fortunately, our batteries lasted and we made it all the way back to the parking lot without getting lost. There we were greeted by familiar colors in the sky – one of the first auroras we had seen in Iceland.

We enjoyed this wonderful spectacle and started back to Reykjavík around midnight, where we spent the night that day.

Our whole trip took about 5 hours including the round trip from Reykjavík, and our expenses were only gas (about 3000 ISK) and parking fee (about 1000 ISK).

How to get to Reykjadalur valley


The hot river in Hveragerdi is among the closest natural thermal springs to Reykjavík. From Reykjavík you can get to the hot river parking lot in about less than one hour and the route is very easy. You have several options to go to the hot river. Probably the most popular and least accessible is driving your own or rented car.

Drive with car

You can easily reach the hot river by car. Leave Reykjavík on road number 1 heading south (Selfoss and Vík).

You drive straight the whole time, along one main road, and after going down a steep hill from the mountains, you reach the small town of Hveragerdi. Here you need to take the third exit to the town at the roundabout near the N1 gas station.

Then you continue straight ahead, drive through the entire town and reach an area where you can see the first smoke and steam from geothermal sites. You will arrive at the parking lot where you will park and hike to the river.

Use bus transportation

Every day, a bus departs from Reykjavík, from the Mjódd bus station in the morning and in the evening, which also goes to the town of Hveragerdi. The bus takes you to the mall, from where it’s quite a walk to even get to the starting position where the hot river hike starts. So if you are going to travel to Hveragerdi by bus, you can plan a minimum half-day trip.


Hitchhiking is a very common and popular method of transportation in Iceland, usually you don’t have to wait too long.

In addition, there are a lot of cars on the route from Reykjavík to Hveragerdi and back almost all day, so this route is almost one of the best for hitchhiking.

Once you get to Hveragerdi, the route is the same as from the bus stop – you have to get outside the town, from where the hike into the mountains to the hot Reykjadalur valley begins.

Take a tour

If you don’t feel confident enough to go to the hot river on your own, a guide can go there.

Tours to hot Reykjadalur thermal river

On we found one hike with a pickup in Reykjavík where the guide takes you directly to Hveragerdi to the hot river.

You will only need towels, swimwear, food and snacks with you, your guide will take care of the rest. We would recommend a tour with a guide especially in bad weather, when you are not sure whether the ride or the hike to the hot river would be safe for you.

What to take with you and how to prepare


What to Take:

  1. Hiking Gear: Wear sturdy, comfortable hiking boots and dress in layers suitable for unpredictable Icelandic weather.
  2. Swimsuit and Towel: Essential for taking a dip in the hot river. A quick-dry towel can be convenient.
  3. Backpack: Carry a small backpack for personal belongings and to keep your hands free during the hike.
  4. Water and Snacks: Stay hydrated with plenty of water and pack some energy-boosting snacks.
  5. Weather Protection: Bring a waterproof jacket, hat, and gloves, as the weather can change rapidly.

How much does Reykjadalur hike cost?

The entrance to hot geothermal river is free.

Parking Fee: If arriving by car, there is a parking fee. For every hour of parking your car on the parking lot next at the start of hike, you must pay 200 ISK (roughly 8 dolars/euros).

Additional Tips:

  • Trail Etiquette: Stay on marked paths to preserve the delicate ecosystem. Respect local guidelines and regulations.
  • Leave No Trace: Carry out all your trash and respect nature.
  • Time Management: The hike and soak can take several hours. Plan accordingly, considering daylight hours and weather conditions.

Trail and hike to river


During our trips to the geothermal river in Reykjadalur, we had the opportunity to try this hike in different weather, whether it was rainy or a little muddy in the fall or on a snowy path in one of the winter months.

The hike is not too difficult, but it is not one of the easiest either.

The first steep hill can take you by surprise, which will take the breath away of even the most experienced hikers. Then the following smaller or larger hills, on an unpaved path, with occasional gravel or the need to jump over small rivers.


The most frequently quoted trip time to Reykjadalur hot springs is 1 hour. This time is on average correct, in the summer months and with a faster walking pace, you can get from the parking lot to the river even faster, on the other hand, in winter, in the rain or after dark, the journey can take an hour and half to two hours, one way.

The length of the hike to Reykjadalur hot river is 3 kilometers. But in hilly terrain and bad weather, even 3 kilometers often seem like a much longer distance.

Changing rooms


As for the changing rooms at this hot spring – there are no covered rooms or facilities. This has always been a bit of a disadvantage for us because you only have a few places to change here with wooden partitions where you get a bit of privacy.

This in itself wouldn’t be a problem until it starts to rain or freeze, as then all your gear and towels can get wet and once you’ve finished your bath in the hot river, you’ll be changing into wet or wet clothes and the walk back to the car park is much less pleasant.


Hot river Reykjadalur

For me and my friends, the temperature in the river was always pleasant and that’s because we were usually there when there weren’t many people there. The temperature of the river is not constant, but changes depending on which part of the river you are in.

The problem can arise if you go to Reykjadalur in the summer, when there are many tourists and the best spots are taken, leaving you with a free part of the river that is either too hot or colder.

According to our experience, we can say that the best parts of the thermal river in Hveragerdi have a temperature between 35-40°C. If you are further from the spring, the temperature is between 15 and 25°C.

Best time to visit Reykjadalur hot springs


I would recommend a trip to the hot river in Hveragerdi to anyone, almost anytime. Of course, there is also the best time of year and day to enjoy your trip as much as possible.

Best time is in summer

Summer days are some of the best to visit this river. On the one hand, you will have a chance of very good weather, the roads will not be soggy, and you will be happy with the lower temperature of the river, if the suitable places are occupied.

In Iceland, however, the days are also longer during the summer months, so you can take a trip to the river even at midnight and stick to the path will not be a problem.

Less suitable months to visit Reykjadalur are, for example, April, May, October or November. In these months, you can expect many rainy days in Iceland, and in April or November even freezing weather, which can complicate the journey along the trail.

Parking at Reykjadalur hot river

If you go to the hot river with your own car, it is best to park at the cafe where the hike to this hot spring begins. However, this parking lot started to be paid for years ago, just like many other tourist-frequented places in Iceland.

You can pay for parking at Reykjadalur easily thanks to the machine that you will find right next to the parking lot. It is paid only after leaving the parking lot. Just enter your vehicle number plate into the machine, confirm the time, pay and then you have 15 minutes to leave the car park. Cameras automatically detect all cars entering and leaving the premises and record your arrival.

If you use local apps to pay for parking in Iceland, you can also use the Parka apps to pay with your mobile.

Other recommended hot springs

As we mentioned at the beginning of the article, the hot river in Hveragerdi is one of the closest geothermal springs to Reykjavík. There aren’t many other similar places in the same area, but you’ll find a few alternatives in the Golden Circle area.

Here you can visit, for example, the oldest pool in Iceland called Secret lagoon. It is a man-made bath in a geothermal area, but even so, the pool itself and the area look very natural.

Another alternative, not far from Secret lagoon is Hrunalaug hot spring. It is a smaller hot spring, which has a really limited number of places, but is definitely worth a visit. It is located in the middle of nature, in a small hidden valley, and it looks completely natural. Here you will find three small pools that can fit about 20 people. Of all the alternatives mentioned, this hot spring is the cheapest, the entrance fee is only 2000 ISK (roughly 15 dollars).

About 40 minutes from the town of Hveragerdi is another popular, but less natural alternative. In the town of Laugarvatn, you can visit the thermal baths or pools called Fontana baths. There are several pools and hot baths, a sauna, and those who like to cool off can go directly from the pools to the local lake.

The last and newest alternative if you are looking for hot springs near Reykjavík is the Hvammsvík baths. These are smaller, newly built swimming pools in one of the Icelandic fjords, about 40 minutes from Reykjavík.
