Where are the top hot springs in Iceland, and what makes them unique? Which ones are natural hot springs, and which are geothermal spas? Can you bathe in them all year long? Read on to find out everything you want to know about Icelandic hot springs.
Iceland is the land of ice, fire, and water. The island sits on one of the earth’s 'hot spots,' resulting in a lot of geothermal activity. However, there are also glaciers all over the country.
All warm water in Iceland is geothermal; it comes boiling from the ground and straight into people's homes. Rather than needing to warm it up, the water must be cooled down to enjoy it.
The geothermal water is the reason for the dozens of swimming pools across the country - with a total of 17 in the greater Reykjavík area alone! All of these pools will provide you with soothing, warm waters that are perfect for relaxing in.
Some of Iceland's hot springs are boiling fumaroles, bubbling mud pits, or spouting geysers, but others are calm pools of water that have the perfect temperature in which to bathe.
Many of these have become popular bathing spots. In some places have natural hot water coming from the ground but no suitable area for bathing.
Here, locals build a pool to contain the water. Sometimes the water is too hot for a dip, but it becomes just the right temperature by mixing it with cold water.
You can find hot springs of all sizes and shapes in Iceland, entirely natural ones or natural ones that have had a little help.
In fact, the term 'hot spring' is a little problematic. People sometimes have different opinions on what can be considered a hot spring in Iceland. You could describe some as warm pools, hot tubs, spas, geothermal lakes, swimming pools, or even geysers.
However, bathing in Iceland's warm waters is equally popular with travelers and locals alike, and the versatility is so great that they should appeal to all types of travelers.
Here you are presented with a few options. Note that the best way to reach most hot springs in Iceland, especially the natural ones off the beaten path,
is to rent a car and drive there yourself.
Iceland boasts some natural hot springs that are free to enter, but they lack facilities such as changing rooms, showers, or bathrooms.
Therefore, several other hot springs and pools charge entry, but in return, they have excellent guest facilities. These have consequently become the most popular hot springs in Iceland. They would be classified by many people as spas, although they all have a hot spring element.
Here you can read about Iceland's most popular spa-like bathing spots and find out what makes them unique.
The Blue Lagoon is the most known and popular hot spring in Iceland by far.
The light blue, milky waters are the perfect 38-39°C (110-102°F) in temperature, and this attraction has been named one of 'The Top 25 Wonders of the World' by National Geographic.
Although the water itself is entirely natural and full of rich minerals such as silica and algae, the lagoon didn't form naturally. It appeared by accident in 1976, caused by a human-made construction.
It wasn't until 1981 that the first person tried bathing in it, and ever since then, its soothing qualities and healing waters have only increased in popularity.
Today, the lagoon is world-famous and the most impressive spa resort in Iceland. It features several restaurants, cafés, an in-water bar, a hotel, a gift shop, and a relaxing area with massage facilities.
The lagoon is ever-expanding in size, but entry is limited, so it never becomes jam-packed even when it sells out.
Because of this, you will need to book your entry well in advance - and it comes with the highest price tag of all the bathing options in Iceland.
The Blue Lagoon is on the Reykjanes peninsula, only a 20-minute drive from Keflavík International Airport and a 30-minute drive from Reykjavík, making it a popular first or last stop for arriving and departing guests.
If you have a short stop in Iceland, you shouldn't miss out on this great bathing spot.
Another lagoon similar in texture and has the same blue color as the Blue Lagoon is the Mývatn Nature Baths. The baths are northern Iceland's answer to the south's famous spa, and it is just as appealing.
The Mývatn Nature Baths are a cheaper alternative and have become the preferred option for those who still crave that milky blue water but feel that the Blue Lagoon may have become a little too popular.
Most likely, the only thing preventing some people from going there is how far it is from Reykjavík.
It’s about a 6-hour drive one way, so Mývatn Nature Baths only suit those on longer journeys who plan to visit the northern part of Iceland.
On-site, you'll find a good shower and changing facilities, as well as a sauna and a café where you can grab some refreshments before or after your soak.
As a plus, the surrounding nature is stunning, making a trip to Lake Mývatn well worth the journey any time of year.
The Secret Lagoon near the village Flúðir is one of Iceland's oldest swimming pools, dating back to 1891.
It was abandoned for years but was renovated and reopened in 2014 with brand new showers and changing rooms.
The pool itself is a comfortable 38-40°C (100-104°F), just like a large hot tub. It’s located near the popular Golden Circle, making it a great place to stop before or after visiting this popular sightseeing route.
Aside from being a fantastic spot to take a dip, the scenery surrounding the Secret Lagoon is well worth the visit. Right next to it are bubbling hot springs, steaming fumaroles, and even a small geyser that erupts every few minutes.
As can be gathered from the name, the water here is unique, as it is geothermally heated seawater rather than spring-water. The water is filled with salt and a host of healing minerals quite different from those in other pools and hot tubs around the country.
This water is pumped up from two nearby boreholes, creating a constant flow through the pools, meaning no chemicals need to be added for hygiene reasons.
The Geosea Sea Baths offer incredible views over the beautiful Skjálfandi Bay, with its glistening ocean and the beautiful mountains that frame it.
There is also a small restaurant on-site with an outdoor terrace, allowing you to enjoy the seascapes with some light refreshments and modern changing facilities.
Fontana Geothermal Baths are located right next to Laugarvatn Lake, about a ninety-minute drive from Reykjavík.
Like the Secret Lagoon, it is also situated near the Golden Circle, making it a great addition to your trip to the famous trail.
The Laugarvatn area sits over a hot zone. People in the namesake village have been using hot water from the ground for heating their houses, cooking, and bathing since 1929.
One of the saunas at the Fontana Baths is the same one used in the past, although it’s since been renovated. The sauna was built over a steaming hot spring, and if it gets too hot inside, guests simply need to open the door to cool it down.
Adventurous guests can also wander down to Laugarvatn lake itself to cool off, even in the wintertime, as the lake is geothermal.
The sand between the baths and the lake is warm due to this activity, and in places, it’s warm enough to cook traditional rye bread by burying the dough in the sand.
You can taste bread freshly baked in the ground at the café located at Fontana Spa’s entrance.

Besides all the human-made, concrete swimming pools with showers and bathroom facilities you can find around Iceland (some of which are truly spectacular such as the infinity pool at Hofsós), several are a cross between a human-made pool and a hot spring.
The water might be all-natural, but someone needed to pile up some rocks or make a concrete structure around it for people to enjoy the place as a bathing location.
These are often in rural locations, only looked after by volunteers, a little hard to get to, and may or may not offer some changing facilities.
It's unlikely you'll come across showers, bathrooms, or trash cans, so remember not to leave anything behind when visiting.

Seljavallalaug is on the South Coast of Iceland, between the waterfalls Seljalandsfoss and Skógafoss.
Although this is a human-made 25-meter long and 10-meter wide construction from 1923, its surroundings make you feel like you're in the middle of nowhere.
The hot water that trickles into it is entirely natural, and the pool is built into a mountainside that acts as its fourth wall. The water isn't very hot, and in wintertime, it's only lukewarm, but on summer days, it's perfect.
Seljavallalaug has two small rooms where people can leave their clothes. Please leave these as tidy as you can as they are only attended to by volunteers very infrequently.
The water in the pool is also only cleaned once every summer. So depending on when you go, it may look a bit dirty. But the tranquillity and beauty around the pool make up for a bit of natural mud.
In 2010, Seljavallalaug got completely covered with ash from the big eruption in Eyjafjallajökull glacier. A large group of volunteers spent days cleaning and restoring the pool to its former state.
The pool is a couple of hours’ drive from Reykjavík. To get there, you just need to head south on the main Ring Road, past Selfoss and Hvolsvöllur. Slow down just before you reach Skógafoss and turn left to go towards 'Seljavellir' on a dirt road. Then it's about a 10-15 minute walk along a gravel track to the pool itself.
In North Iceland, on the west side of Skagafjörður fjord, you can find two pools right by each other, Grettislaug and Jarlslaug.
They are circular with piled rocks surrounding them and have fantastic views over the mountains and the sea, where the island Drangey stands tall.
Grettislaug is named after Grettir the Strong, a famous Viking from the Icelandic Sagas. Here you have access to an outdoor shower, and the changing facilities are inside a little turf house.
These pools are on private property, so there is a small entrance fee.

At the end of Road 643 on the eastern coast of the Westfjords, you'll find the stunning Krossneslaug pool.
Warm water from hot springs in the nearby mountains flows into the pool, and there is also a slightly warmer hot tub to the side of it.
The pool has simple changing and showering facilities and an honesty bucket where you can pay 500 ISK for entry and keep the facilities clean.
Despite the long drive on a gravel road to reach it, this pool is loved by its visitors because of its fantastic views and the feeling it provides of being at the edge of the world.

Guðrúnarlaug is a reconstructed historical hot pool, named after Guðrún Ósvífursdóttir, one of the most well-known women from the Icelandic Sagas.
These thermal baths have existed for more than a thousand years but were blocked by a landslide for 140 of them. The reconstruction opened in 2009, to the delight of visitors.
Gudrunarlaug is in West Iceland, on the way to the Westfjords.
To reach it you have to rent your own car as no scheduled buses or tours go here.
Head north from Reykjavík on Ring Road 1, turn into Road 60 towards the Westfjords and turn left onto Road 589 until you reach Hotel Edda, located right by the hot spring.
Entry is free, and there is a small changing room on site.
Found near the Grótta lighthouse in the greater Reykjavík area is the little footbath Kvika.
Artist Ólöf Nordal designed this human-made hot spring, and it sports one of the best views in town, looking over the city mountain Esja and the mighty Snæfellsjökull glacier.
Ólöf carved a small bathing pool, about 80-90 cm wide and 25-30 cm deep, into a large rock.
The water, which is a constant trickle of warm water, comes from a nearby borehole and is cooled down to around 39°C (102°F).
Both Kvika and Grótta lighthouse are popular locations for locals to watch the sunset or the Northern Lights. The view makes it one of the great places to visit in Reykjavik.
However, please note that while there are no changing facilities in the area, as Kvika is only designed as a footbath, entry is free.

You've read about the geothermal pools, but there are also hundreds of scenic hot tubs to be found within Iceland as well.
Each public swimming pool in Iceland boasts at least one hot tub. There can be up to 6 or 7 hot tubs in some cases, and they are also not uncommon in private residences and at hotels.
If you'd like a private hot tub, then you could look into renting a remote summer cabin. A large percentage of Icelandic summer cabins come with a hot tub.
The following list contains the best human-made tubs to visit. They are in spectacular settings, often with views towards the impressive mountains or the enchanting sea.

In the center of the small town of Drangsnes in the Westfjords, you'll find three hot tubs right by the seaside. These tubs have free entry, and you can go in there at any time of the day or night.
The temperature varies from one hot tub to the next, but they are between 38-42°C (100-107°F).
Across the road is a small changing facility, and you'll be sure to meet some friendly locals once you get into the tubs.
When you get too hot, then you can cool off in the sea nearby. Just be careful on the rocks.
There aren't many hot springs to be found in East Iceland, but the Hoffell hot tubs make up for it.
The tubs are all neatly submerged into a bed of rocks, and the views of the surrounding snow-capped mountains are spectacular.
There are four different hot tubs located right next to each other. There is a small entry fee, but those staying at the nearby Glacier World accommodations can take a dip for free.
The hot tubs are situated 20 km west of the town of Höfn in East Iceland. Turn from the Ring Road onto Road 984 towards Glacier World Guesthouse to reach them.
Krauma Spa is one of the newest members on this list, as it only opened in late 2017.
This modern location is next to Europe's most powerful hot spring, Deildartunguhver, where it gets all its hot water.
However, as Deildartunguhver is nearly boiling, the water at Krauma must be cooled down using locally sourced and pristinely fresh glacier water.
You can relax in six beautiful black marble tubs, with a view towards the seething Deildartunguhver, or enjoy the soothing saunas on the premises.
Five of these tubs are warm with varying temperatures, while one is cold, 5-8°C (41-46°F), excellent for boosting your blood circulation.
There are shower and changing facilities, as well as a modern restaurant on-site. Furthermore, as the place is relatively new, it's still a bit of a secret amongst travelers, so there may not be many other visitors around.
A visit to Krauma Spa is certainly one of the best ways of unwinding in West Iceland.
For a hot tub with a twist, why not try the Bjórböðin Beer Spa at the Kaldi brewery in Árskógssandur in North Iceland?
Here you can enjoy the views of Eyjafjörður fjord and Hrísey island, with a cold one in your hand, soaking in hoppy, warm beer! The warm beer is said to do wonders for your skin, and after a good soak, you tuck in at a relaxation area.
There is no age limit to the spa as the bathwater is undrinkable. Who would want to drink warm beer anyway?
You can book your entry and find out more here: Bjorbodin Beer Spa in North Iceland.
Besides the numerous swimming pools and hot tubs you can find within the larger Reykjavík area, there's also the city's geothermal heated beach Nauthólsvík. It’s another great budget activity to check off in Reykjavik.
Here you'll find both a hot tub at the edge of the seawater, as well as a broader but shallower warm pool by the changing facilities.
Next to the changing facilities are also bathrooms, showers, a sauna, and a small café.
The water in the hot tub by the sea varies in temperature, from 30-39°C (86-102°F), but the shallower pool is a constant 38°C (100°F).
Even the sea right by the beach is heated here during the summer months and is about 15-19°C (59-66°F) within the rock fence.
Entry is free throughout the summer months (from the 15th of May until the 15th of August). In winter, the opening times are shorter, and a small fee applies to the changing facilities.
What about the natural hot springs out in nature, where there's no entry fee?
A few dozen of them exist (some of which locals still want to keep secret, so they aren’t ruined!) But the question remains: Which ones should you visit?
To get an idea of their differences, read about these top 5 natural hot springs in Iceland, but keep in mind that there are several others to choose from, some more inaccessible than others.
You can reach these hot springs by joining a hot spring tour or renting a car and driving there yourself.
Photo from Hot Spring Hike of Reykjadalur Valley
Reykjadalur (literal translation: 'Steam Valley') is one of the easiest hot spring areas to reach from Reykjavík.
The hike is not very demanding, although it is mostly uphill. The path is not recommended for people that are afraid of heights since you'll be hiking along the top of a deep gorge at one point.
Photo from Hot Spring Hike of Reykjadalur Valley
If you are in good shape and don't make many stops along the way, you should reach the river after 45-60 minutes. However, the hike could take up to 90 minutes one way.
The duration depends on how fast you walk and how often you stop to take pictures of the waterfall in the gorge and all the pretty bubbling muddy hot springs on the way.
There are no facilities for changing your clothes when you get up there as this is real nature.
You can reach the Reykjadalur river on this hiking hot spring tour.
You can find Hellulaug in the Westfjords, just about 500 meters east of Hotel Flókalundur.
If you are crossing Breiðafjörður fjord with the ferry Baldur, perhaps making a stop at Flatey island, then this hot pool is only a 5-minute drive from Brjánslækur where the ferry docks.
The pool is not seen from the road but is right next to it.
The water is a comfortable 38°C (100°F), and the pool is about 60cm deep. If you get too hot, you can always cool down in the sea, which isn't far off!
No changing facilities, bathrooms, or showers are in the area.
Everywhere you look, you'll see sandy mountains in red, blue, green, yellow, purple, and black - and the best thing to do after an exhausting day of hiking is to relax in the hot geothermal pools that are waiting for you next to the campsite.
The pools stay consistently warm throughout the summer and have a steady stream of hikers relaxing in them. It is the perfect highland oasis.
Take note that some parasites have been found in these pools in the past, but they are considered harmless.
However, if you are allergic to mosquito bites, you may want to abstain from entering the pools.
Landmannalaugar is only accessible during the summertime and only with a 4WD car.
To get there, you'll need to cross some rivers, so if you're not used to driving in the highlands, you may want to take a bus or go on a super jeep tour to get there.
If you drive yourself, then go carefully and make sure you cross rivers where they are at their widest (as they are deeper and run faster where they are narrow). Ask other drivers you meet where it is best to cross, as the rivers are always changing.
If you’re short of time, Landmannalaugar can even be explored in a day. It remains one of the most epic places to explore in Iceland’s stunning highlands
Here you'll find not just a natural hot spring to bathe in, but a natural hot waterfall as well! Laugavallalaug is situated high into the eastern highlands, so this natural pool is more challenging to reach than others.
You'll need a sturdy car to get near it as you need to drive up a 7km F road that's only passable for 4WD vehicles. Then there is a short 200-meters walk to reach the pool.
Alternatively, you can drive a 2WD car to Kárahnjúkar dam, then hike alongside Hafrahvammagljúfur canyon to the warm waterfall.
The hike takes around 7 hours (with time for bathing included).
There are also two very nice natural pools, with a circular stone wall at the highland cabin Laugarfell that isn't too far away (and easier to reach). It’s the perfect place to spend the night when exploring the area.
Super Jeep tours and hiking tours operate from here or from the nearby town of Egilsstaðir.
Also, in the eastern part of Iceland and relatively close to Laugavallalaug, make sure to visit the Víti crater in Askja, which is not to be confused with Víti in Krafla. The literal meaning of Víti is 'Hell.'
The water temperature varies from 20° to 60°C (68° to 140°F), and the bottom is muddy.
The eastern part of the volcanic crater can be dangerous in places where the mud is scalding hot. There is also a high amount of sulfur in the water, creating steam that can cause people to faint.
But the place has been described as one of the most magnificent spots in Iceland. Whoever stands on the edge of this crater will never forget the experience!
If you are not familiar with hot springs, it may be hard to tell the difference between those that are safe to enter and the ones that are not if there are no warning signs.
There are plenty of hot springs, pools, hot tubs, and geysers in Iceland, both natural and human-made, that you should not bathe in.
Most of the time, this is because it's simply too dangerous, either because the water is too hot, too unstable, or too cold.
It should go without saying that any hot spring with large boiling bubbles is too hot to enter.
These hot springs are fenced off in the most famous geothermal areas and will have a warning sign telling you to be careful. However, that may not be the case with all hot springs in Iceland.
Any lake with icebergs floating in it is too cold to enter. Don't bathe there, and don't stand on the icebergs as they can tip over at any given time and trap you in the water.
Although it has almost entirely stopped spouting water into the air, the geyser Geysir still contains boiling water that is far too extreme to enter.
Geysir’s geothermal area has various smaller geysers, including the famous Strokkur, which erupts every few minutes.
Several steaming pools and springs look especially alluring on a cold winter's day.
As Geysir is one of the most frequently visited areas in Iceland, these hot springs are all fenced off, and you will find warning signs detailing that they are indeed up to 100°C (212°F) hot.
However, in the year 2000, Geysir had an unexpected big eruption. A large gathering of people that had been standing too near had to run for their lives, with a couple of them burning their feet or legs from the scalding water.
The earth surrounding the geysers can also be extremely hot, which is why people are asked to keep to the paths so their feet do not sink into the burning mud.
So it's always wise to be careful at any geothermal area you may visit in Iceland.

The water temperature in Grjótagjá varies and became too hot for dips in the late 1970s (about 50°C or 122°F). It's been cooling down since but may still be too hot to bathe in, depending on the day and the recent earthquake activity.
Because of the water's varying heat, loose rocks in the cave, and the extremely slow water flow, it is now forbidden to bathe in the water.
Seeing it because of its spectacular beauty is well worth it, though, and you can always go around the corner and bathe in Mývatn Nature Baths!
Grjótagjá (Rocky Cleft) is not close to Reykjavík. If you happen to be traveling in the North of Iceland, staying in Akureyri, and want to explore the stunning nature around Lake Mývatn, then you're not far away from Grjótagjá.
To get there: Drive east from the village Reykjahlíð (that's on the Ring Road), for a couple of kilometers, then turn right just before you reach the road to Mývatn Nature Baths.
The Reykholt village in West Iceland is one of the most important historical locations in the country.
It’s here where the medieval historian, poet, and lawmaker, Snorri Sturluson, lived. He also apparently bathed here because it’s here where you can find his pool, Snorralaug.
The pool is one of Iceland's oldest structures, and since this is a historical location, bathing is forbidden. The water temperature is said to vary, becoming extremely hot at times, so bathing there could also be dangerous.
The pool is small, only around 4 meters in diameter and 0.7-1 meters deep. Therefore, it would not handle the swarms of bathers and would quickly become dirty and unappealing for visitors.
However, visitors don't come here to bathe. They visit the nearby Snorrastofa museum and learn about history, Norse mythology, and the man who lent his name to the pool, Snorri Sturluson.
With its beautiful blue color, Bláhver looks like the ideal spring in which to bathe, appearing calm, and showing no signs of geothermal activity.
You might instantly think of how great a picture of you relaxing in the azure waters would look. But this hot spring is hiding deadly hazards.
Not only is Bláhver scalding hot, meaning any bathing attempt will result in severe burns, but its edges are fragile and could break if walked on, making any escape attempts difficult.
Luckily, this hot spring, along with several others nearby in the geothermal area of Hveravellir near Lake Mývatn, is fenced off so guests can enjoy its beauty (and smell) from afar.
However, there is an enjoyable bathing pool close by, filled with naturally hot water from the area that has been cooled down.
This natural feature looks ideal for bathing, and some daredevils have entered its waters, as can be seen in the video above.
This clip was shot years ago (on a very calm and sunny day) before a ban on bathing was enacted due to this natural pool’s incredibly dangerous surroundings.
Brimketill is not a hot spring, and its waters are far from being on the warm side. All you will get here is the Atlantic Sea, which is cold enough to give people hypothermia if they stay in for too long.
On top of that, seawater continually sprays the slippery rocks. Brimketill is not a place you want to slip and fall.
On a beautiful, sunny day, the water may look appealing, but most of the time, this area has strong winds blowing through, with towering waves crashing on the rocks. Besides, sunny days in Iceland are few and far between.
The name Brimketill means 'Whitewater Cauldron,' due to the constant white rolling of the waves breaking on the surrounding rocks. The sight is impressive to see from a safe distance.
You can reach Brimketill by driving along the Reykjanes peninsula or joining a tour of the area.
