Katla Ice Cave Tour | Departure from Reykjavik

South Iceland is the most popular part of the country amongst travellers and contains some of Iceland’s most beautiful natural attractions.

Amongst these are the sites of the world famous Golden Circle, and the features of the South Coast, such as the beautiful Jökulsárlón glacier lagoon.

The south of Iceland can be roughly split into two areas, the lowlands in the west, and the east.

The South Icelandic lowlands

The South Icelandic lowlands stretch nearly 100 kilometres (over sixty miles) from Hellisheiði in the west to Eyjafjallajökull in the east. This region is flat and fertile farming land, and home to many Icelandic horses and sheep.

The whole area is geologically very young, formed during the last Ice Age by the lava flows from numerous volcanoes in the area. The lowlands are surrounded by volcanically active mountains, notably the aforementioned Eyjafjallajökull and Hekla.

The most notable features of the South Icelandic lowlands are the three on the Golden Circle, the country’s most popular sightseeing route.

These consist of the Geysir Geothermal Area, where geysers erupt and hot springs bubble, Gullfoss, a powerful two-stepped waterfall, and Þingvellir National Park, an oasis of forests and lava located between the tectonic plates.

The fissures and lava landscapes of this latter feature reveal the extent to which earthquakes and eruptions have shaped the region. The area is still very active; take, for example, the 1975 eruption in the Westman Islands that nearly destroyed the town and formed a new island.

It should be noted that Þingvellir is not just a site of natural, geological wonder. It was also the original site of the parliament Icelanders formed in 930 AD. This was a convenient place, considering the fertile lands of south Iceland meant that many settlers populated it.

Unlike most early Icelandic settlements, few of the communities formed in the south were based off fishing. The only town with a significant harbour in the south is Þorlákshöfn, where the ferry to the Westman Islands leaves.

Other towns in the lowlands are Selfoss, Hveragerði, Hella and Hvolsvöllur, all conveniently located by the Ring Road.

In terms of culture in the lowlands, it was once home to the ancient bishop seat of Skálholt. Also, Iceland's most famous saga, Njal's Saga, takes place in the region.

For sports, horse riding is popular, as is fishing for salmon and trout, hiking, snorkelling, sightseeing and river rafting.

Eastern South Iceland.

The areas south and east of Mýrdalsjökull, the glacier that covers the volcano Katla, are considered the eastern part of south Iceland. Glaciers, volcanoes and the Highlands dominate the view.

This landscape has also been shaped by volcanic eruptions, although these were much more recent, and thus the area looks dramatically different. Vast expanses of black sand stretch from the Highlands to the sea, part of several glacial outwash plains that flood during a volcanic eruption.

Some agriculture is found here, with farms nestled in the mountains, but because of the glacial floods, they are few and far between.

A few large glacial rivers flow through this area, creating incredible features such as Skógafoss and Seljalandsfoss. These are hardly the only sites in this part of the south worth seeing, however.

Sólheimajokull is a beautiful outlet glacier, a tongue of the greater Mýrdalsjökull, that you can hike on so long as you are with a guide. Skógar has a very interesting museum that discusses national traditions during Iceland’s development. One of Iceland’s most famous hiking routes, Fímmvörðuháls, cuts through the area.

Southwest of the village of Vík is one of Iceland’s most spectacular beaches, Reynisfjara. Near the promontory of Dýrholaey, and boasting incredible views of the Reynisdrangar sea stacks, it is a marvellous stretch of black sand.

Even further east is the Skaftafell preservation area, an area so beautiful it was once a national park in its own right. Today it is part of the greater Vatnajökull National Park, which covers parts of the south, east, north and much of the Highlands.

Just a little further from here is the incredible, world famous Jökulsárlón glacier lagoon, a deep lake that fills with icebergs. At the adjacent Diamond Beach, they wash upon the shore.

Skógafoss is one of Iceland’s biggest and most beautiful waterfalls with an astounding width of 25 meters (82 feet) and a drop of 60 meters (197 feet).

Due to the amount of spray the cascade produces, at least one rainbow is present any time the sun emerges from behind the clouds.

Located on the Skógá river, this mighty cascade is clearly visible from Route 1 and is an excellent place to stop and stretch the legs while travelling Iceland’s South Coast. The river below Skógafoss holds a large char and salmon population and is thus a favourite spot for fishermen in the summer.

The land underneath the waterfall is very flat, allowing visitors to walk right up to the wall of water. This will get you drenched, although, on a summer’s day, it can be quite tempting.

Skógafoss can also be viewed from the top as a steep staircase leads to an observational platform above the cascade. Many nesting seabirds can be found on the route up.

Geography

Skógafoss is located near the small village of Skógar, south of the Eyjafjallajökull glacier volcano. There you’ll find the Skógasafn folk museum, an open-air museum with both old wooden houses and turf houses, as well as a regional museum with various artefacts from this area.

A part of the Skógasafn Regional Museum is the Museum of Transportation, which showcases the history and evolution of transportation, communication and technologies in Iceland. There, you can see how this nation evolved from the age of the working horse to the digital communications of the 21st century.

The Skógasafn museum also includes a café and a museum shop, and in the village of Skógar, you will find both a hotel and a restaurant.

At the eastern side of Skógafoss, you will find one of Iceland’s most famed hiking routes; the Fimmvörðuháls pass. The 22 kilometre (14 miles) trail takes you along Skógá river, between two glaciers, Mýrdalsjökull and Eyjafjallajökull, before ending in the beautiful Þórsmörk valley.

Skógafoss is often visited alongside the waterfall Seljalandsfoss, which is just a little further along the South Coast. Both fall from cliffs of the same height, and while Skógafoss is much more powerful, Seljalandsfoss has a cave behind it, which means it can be fully encircled. It is also next to a much lesser known but still awe-inspiring waterfall, Gljúfrabúi.

Folklore

A gold ring is on display at the Skógasafn museum. According to legend, the ring is from a chest that was owned by Þrasi Þórólfsson, one of the first Viking settlers in the area, who by some accounts was a giant. Folklore states that before his death in 900 AD, Þrasi buried a chest filled with gold in a cave behind Skógafoss waterfall.

Many attempts were made to retrieve the chest after Þrasi’s death, and years later, locals managed to grasp a ring on the side of the chest. As they pulled, the ring broke off, and the treasure was lost forever. The ring was then given to the local church before it made its way to the museum.

Seljalandsfoss is a waterfall that can be fully encircled, situated on the South Coast of Iceland with a drop of 60 metres (200 feet).

Due to the waterfall’s close proximity to the Ring Road and impressive natural features, it is one the country's most famous and visited falls. Majestic and picturesque, it is one of the most photographed features in all of Iceland.

Geology and Surroundings

Seljalandsfoss waterfall, part of the river Seljalandsá, has its origins underneath the glacier Eyjafjallajökull. The volcano beneath this ice cap was the one that erupted in 2010 and caused havoc at airports across Europe.

The cascade of the falls is relatively narrow but falls from a tall cliff that once marked the country's coastline, the sea is now located across a stretch of lowlands and is visible from the site.

The most distinguishing feature of Seljalandsfoss is a pathway that stretches all the way around it. The cliffs behind the falls have a wide cavern, and rocks and paths allow guests to fully encircle it in summer.

Though a mesmerising opportunity, visitors should be prepared to get dampened due to the perpetual mist of the falls, which also tends to make the rocks of the pathway slippery. 

Floodlights have been set up on both sides of the waterfall, which impressively illuminate the scene during the night when the midnight sun is not out. The lights were installed in 2001 due to the growing popularity of the falls as a tourist destination.

After visiting Seljalandsfoss, it is common for visitors to continue north to the waterfall Gljúfrabúi, which is found partially hidden behind a rock face. Because of Seljalandsfoss extreme popularity, Gljúfrabúi is widely considered the hidden gem of the scene, as it is too often overlooked.

Seljalandsfoss is also usually visited alongside the nearby Skógafoss. The waterfall falls from the same height, and while it cannot be encircled, it is much more powerful and steeped in the legend of a giant’s hidden treasure.

Visitor Centre Controversy

In 2017, it was announced that a visitor’s centre was to be constructed near the falls. The design of the building indicated that it would be seven metres (23 feet) high and 2,000 square metres (21,500 square feet) in size. Landowners in the area opposed to the idea, proclaiming that the centre would greatly alter the natural appearance of the waterfall’s renowned scenery.

The project has neither been fully approved nor wholly cancelled, with ideas surfacing of either significantly reducing the size of the construction, or moving the visitor centre’s location further away, for instance to the nearby farmstead Brekkuhorn.

Seljalandsfoss in Popular Culture

Along with a multitude of South Iceland’s most famous natural attractions, Seljalandsfoss can be seen in Justin Bieber’s music video for his song ‘I’ll Show You’. Please enjoy the video without emulating any antics that will endanger yourself or the environment.

The waterfall was also a featured waypoint during the first leg of the sixth season of The Amazing Race, an American reality TV series.

The glacier volcano of Eyjafjallajökull is notorious the world over for causing havoc to air travel in 2010, and stumping television anchors everywhere as they tried to pronounce it. 1651 metres (5427 feet) tall, it is one of the most dominant features of the South Coast.

Geography

The glacier of Eyjafjallajökull is approximately 100 square kilometres (39 square miles), making it the country’s sixth largest. It sits close to the fourth greatest, Mýrdalsjökull, which also conceals another notorious volcano, this one called Katla.

While Eyjafjallajökull’s eruption was huge and disruptive, it pales in comparison to the potential of Katla. Far more explosive, and under much thicker ice, an eruption here in unfavourable wind conditions could have worldwide consequences.

The magma chambers between both of these mighty volcanoes are connected, and, unfortunately for us, an eruption at Eyjafjallajökull is usually followed by one at Katla within a decade.

Eyjafjallajökull has many glacial outlets, the most famous being Gígjökull. Many rivers flow from its meltwater, and one of these falls into the beautiful South Coast waterfall, Seljalandsfoss, which it is possible to fully encircle.

Eruptions

Eyjafjallajökull’s most recent eruption was no doubt the most famous in Iceland’s history (although the honour really should go to Laki, the 1783-4 eruption of which caused an ash cloud so great that Europe fell into a famine that many historians believe led to the French Revolution). On March 27th, 2010, magma began to bubble from beneath the surface, and by April 14th, ash was starting to billow from the peak.

800 people were evacuated, in fears not of magma, but of equally dangerous glacial floods, which have decimated Icelandic towns in the past. Animals were ordered to be kept inside, and those with respiratory problems told they should also stay indoors.

Air travel across Europe was halted, as, by the evening of April 15th, the ash was already over the UK, Scandinavia, and parts of Germany. Holidaymakers were trapped, waiting for news, and would end up stuck for eight days; in Scotland and Ireland, there were even flights delayed in May due to lingering effects.

Thankfully, no one was injured, although the ash is thought to have caused respiratory issues for some in the south of the country. Many farms were also destroyed by the ash and floods, with some farmers still struggling to recover today.

Since settlement in 874, Eyjafjallajökull has also erupted in 900, 1612, and from 1821 to 1823. The latter released a huge amount of fluoride which is believed to have affected the bone health of humans and animals alike at the time.

Eyjafjallajokull today

Eyjafjallajökull is now entirely safe to visit and is seen on most tours of the South Coast in clear weather. In the town of Hvolsvöllur, there is a visitor’s centre on the volcano, which focuses on the experience of one family whose farm, Þorvaldseyri, was one of the many destroyed by the floods, lava and ash.

It is very unlikely that Eyjafjallajökull will erupt again any time soon, with hundreds of years between each eruption, but as mentioned, its neighbour Katla might start rumbling...

Katla is one of Iceland’s most explosive volcanoes, located underneath Iceland’s fourth largest ice cap, Mýrdalsjökull. Since settlement, it has erupted, on average, once every fifty years, with the last eruption in 1918. It is long overdue.

Katla is connected to Eyjafjallajökull, which erupted in 2010 and caused widespread disruption to air traffic, as well as changes in climate. Usually, Katla is triggered by an eruption here, usually going off within the decade afterwards. Kristín Jónsdóttir said in 2016 that it was ‘a matter of when, not if’ Iceland would face the wrath of Katla once more.

Katla means ‘Kettle’ in Icelandic, and many women are named after the volcano with it being one of the more popular girl’s names.

Geography and geology of Katla

Katla is located on Iceland’s South Coast, north of the village of Vík. Its peak is 1,512 metres (4,961 feet) above sea level, and its crater is 10 kilometres (6.2 miles) wide. The ice of Mýrdalsjökull is, 700 metres (2,300 feet) thick at certain points over it.

Because of this huge amount of ice, some smaller eruptions do not even break the surface. However, even these can be very dangerous, as they can still cause unexpected floods as the melted water seeps from under the glacier. One only needs to see the black sand desert of Sólheimasandur to see how much life can thrive in the glacial outwash plain under Katla.

Because of the floods caused by Katla, Iceland’s South Coast has very few settlements. Floods such as these have wiped out entire villages before.

The floods following the 1918 eruption were particularly powerful, clearing away huge swathes of land. The lava that followed, however, was so voluminous that it extended the southern coastline over five kilometres (eight miles) out to sea.

Though Eyjafjallajökull and Katla have a relationship of exploding in quick succession, they are part of different volcanic systems. Katla’s system has an area of 595 square kilometres (230 square miles), and is connected to the Eldgjá canyon.

Tours on Katla

Katla is beneath the peak of Mýrdalsjökull, which is surrounded by outlet glaciers, making tours on it few and far between - after all, it is very difficult to reach. Some helicopter tours, however, will make a landing here. Some super jeep tours also take the bumpy but beautiful path to the top.

It should be noted that there are ice caves above Katla, which are accessible for longer throughout the year than the ice caves at Vatnajökull. These ones, however, do not have blue ice.

Where to see Katla

Katla can be seen from the Ring Road, which encircles Iceland, by travelling along the South Coast, so long as the weather is clear. It will be visible for much of the drive, which also takes you passed features such as the waterfall Seljalandsfoss and the black sand beach of Reynisfjara.

It can also be viewed when visiting one of the glacier tongues of Mýrdalsjökull, such as Sólheimajökull, the most popular outlet for glacier hiking.

Mýrdalsjökull is a glacier in the south of the Icelandic highlands. It is the country's fourth largest ice cap, covering nearly 600 square kilometres (232 square miles), and its highest peak is almost 1500 meters tall. It is most well-known for sitting atop the notorious and explosive volcano, Katla.

Mýrdalsjökull is visible from Route 1 on the South Coast, sitting to the north of the village of Vík. It is visited on some snowmobiling, ice caving and helicopter tours, and one of its glacial outlets, Sólheimajökull, is the most popular place in the country for ice-climbing and glacier hiking.

Eruptions beneath Myrdalsjokull

Since 2010, the world has known of the volcano beneath Eyjafjallajökull; after all, it halted European air travel for over a week and stumped news readers everywhere. Few, however, are aware of the much larger volcano right beside it.

Mýrdalsjökull conceals Katla, one of the country’s most active volcanoes, having erupted, on average, once every fifty years since 930 AD. Because of the glacier above it, these eruptions tend to cause enormous ash clouds. It is these ash clouds that lead to flights being grounded, crops and livestock poisoned, and have the potential to change the world’s climate.

The last major eruption beneath Katla was in 1918, in which such huge lahar floods occurred that the southern coastline was extended five kilometres outwards. This area is also very susceptible to glacial floods, or 'jökulhlaup', during eruptions, even when the lava does not break through the surface of the ice. These are as dangerous as the lava itself, having wiped out whole Icelandic villages before.

Historically, the area was little settled for this reason.

Katla is connected to the same volcanic system as Eyjafjallajökull and usually erupts violently a few years after Eyjafjallajökull does. As the ex-president, Ólafur Ragnar Grímsson said in 2010:

So it is currently several years overdue. Katla is monitored heavily, and roads around it closed when seismic activity increases. All road closures around Iceland can be found on Road and Coastal Administration's website.

Tours on Myrdalsjokull

While there are no eruptions immediately imminent, tours continue to run onMýrdalsjökull, allowing visitors to enjoy the glacier. It is, for example, possible to snowmobile across its surface throughout the year and take ice caving tours beneath it from October to April, with departures from both Reykjavík and Vík.

Considering the ice caves under Vatnajökull glacier are usually only accessible from November to March, this provides a wider window of opportunity for travellers to Iceland outside of the depths of winter. It should be noted that the caves in Mýrdalsjökull do not have the same blue ice, however.

Tours around Myrdalsjokull

Mýrdalsjökull can be seen on all South Coast tours that reach Vík and beyond in clear weather. It can also be seen from above on helicopter tours that depart from Reykjavík.

The best perspectives of the glacier, however, can be found on the popular Fimmvörðuháls hiking trail, which goes between Eyjafjallajökull and Mýrdalsjökull. Part of this hike can be done in a day, or you can take the complete route from Þórsmörk to Skógar on a three-day trek

The South Coast of Iceland is the country's most visited sightseeing route, along with the Golden Circle.

This incredible shoreline stretches from the greater Reykjavík area in the west to the magnificent Jökulsárlón glacier lagoon in the east and is lined with countless natural wonders such as cascading waterfalls, volcanoes, black sand beaches and glaciers.

Geography, Nature & Wildlife

The South Coast is the most easily accessible part of the country’s southern region, found along the Route 1 highway (the Ring Road), which encircles Iceland. The area consists of a diverse lowland that transitions between, marshlands, bays, cultivated pastures, estuaries and black sand deserts.

Underneath the soil rests a vast lava field, known as Þjórsárhraun. Its edges reach several hundred metres offshore where the ocean waves crash upon them, thereby protecting the lowland from the invasion of the sea. This results in the South Coast being unusually lacking in the deep fjords that so distinctly characterise the rest of Iceland's shoreline.

The region boasts vibrant bird life during all seasons. Freshwater birds nest in the marshlands and around the estuaries, while seabirds flock around the cliffs of Reynisdrangar and Dyrhólaey, including the North Atlantic puffin between May and August. Some species stay throughout the harsh Icelandic winter, including the northern diver, the loom and various species of gulls and ducks.  

Seals are often found along the shore, particularly around the Jökulsárlón Glacier Lagoon and Diamond Beach. As with everywhere in Iceland, you should always keep an eye out to sea, as whales and dolphins reside all along its coastline.

Highlights of the South Coast

The South Coast offers an unprecedented array of natural wonders that draw thousands of visitors each day.

When driving the route from Reykjavík city, the first major features are the two great waterfalls of Seljalandsfoss and Skógafoss, which sit beneath the notorious subglacial volcano, Eyjafjallajökull. On clear days from these beautiful cascades, the Westman Islands can be seen across the ocean.

A little further down the route is the glacier Mýrdalsjökull, which covers one of Iceland’s most explosive volcanoes, Katla. Many glacier hikes are taken here upon the outlet of Sólheimajökull.

The aforementioned Dyrhólaey cliffs are next, home to many seabirds. Even if you come outside of puffin season, they are well worth a visit; jutting out to sea is an enormous rock arch of the same name, which you can marvel at from many angles.

Adjacent to the village of Vík is the famous black-sand beach, Reynisfjara, home to the rock pillars of Reynisdrangar, said to be two trolls frozen by the light of the sun. Though beautiful, this area is gaining notoriety for its dangerous sneaker waves, so visitors should be sure to stay well away from the edge of the water, even on a calm, still day.

There are no landmasses between Reynisfjara beach and the continent of Antarctica, so you can imagine how the waves can build momentum.

After passing through Vík, you will cross the glacial sand plain of Skeiðarársandur, before entering Vatnajökull National Park, home to the largest ice cap in Europe, Vatnajökull itself, dozens of glacial outlets and the magnificent Jökulsárlón glacier lagoon.

While almost all of these sites can be seen from Route 1, they make up a fraction of what the South Coast has to offer. The vast sand plains of Sólheimasandur are home to a crashed DC-3 Plane Wreck, and within the Vatnajökull National Park is the dramatic Skaftafell Nature Reserve.

Less than a kilometre from Seljalandsfoss is the hidden gem of Gljúfrabúi waterfall, and short distances from Jökulsárlón you will find the Diamond Beach, where icebergs wash on the black-sand shore, and another glacier lagoon, Fjallsárlón.
