Vatnajökull glacier is the largest glacier in Europe, covering 8% of Iceland’s landmass.

It is the central feature of the Vatnajökull National park, found in the south west of Iceland, a popular spot for activities like glacier hiking from Skaftafell, boat tours in the Jökulsárlón glacier lagoon, and ice caving tours between November and March.

Facts about Vatnajokull

Vatnajökull has a surface area of approximately 8,100 square kilometres (3127 square miles); though it is rapidly shrinking due to climate change, its recession is not quite as advanced as at other glaciers, such as Langjökull and Mýrdalsjökull. In parts, it is a kilometre deep (over three thousand feet), and its average thickness is around half of that.

Vatnajökull also holds the tallest peak in Iceland beneath its ice; Hvannadalshnjúkur is 2,200 metres tall (7,218 feet). It also conceals some of the most active volcanoes in the country, the most notable being Grímsvötn, Öræfajökull and Bárðarbunga.

Volcanic activity in the region has occurred on and off throughout the centuries, and many geologists believe that several eruptions are overdue. If their calculations are correct, it would mean significant volcanic activity for Vatnajökull over the scope of the next half-century.

Depending on winds, this could result in worldwide consequences in terms of air-travel, agriculture and the general climate.

The glacier boasts over 30 outlet glaciers, which are channels of ice that flow out of ice caps but remain constrained on the sides of the valley. The major outlet glaciers of Vatnajökull include Dyngjujökull in the north, Breiðamerkurjökull, and Skeiðarárjökull to the south. To the west, one can find the outlet glaciers Síðujökull, Skaftárjökull and Tungnaárjökull.

Numerous rivers run out of Vatnajökull, making up some of the greatest glacial rivers in Iceland. The most notable are:

• Tungnaá (west)

• Köldukvísl (west)

• Þjórsá (west)

• Jökulsá á Fjöllum (north)

• Skjálfandafljót (north)

• Jökulsá á Brú (northeast)

• Jökulsá í Fljótsdal (northeast)

• Jökulsá í Lóni (south)

• Hornafjarðarfljót (south)

• Jökulsá á Breiðamerkursandi (south)

• Skeiðará (south)

• Núpsvötn (south)

• Hverfisfljót (south)

• Skaftá (south)

Vatnajokull National Park

Vatnajökull National Park was established in June 2008 and has slowly grown to include more and more areas. The park now covers an area of 14,141 square kilometres (5,460 square miles), 14% of the country. It is the second largest national park in Europe.

Rivers divide the highland plateau to the north of the park. The volcanic table mountain Herðubreið towers over this particular region, along with volcanoes Askja, Snæfell and Kverkfjöll.

The canyon Jökulsárgljúfur was carved out by glacial floods centuries ago. At the upper end of the canyon, you'll find Dettifoss, the most powerful waterfall in Europe. Further north, the horseshoe-shaped canyon Ásbyrgi is believed to have formed when Óðinn's eight-legged horse, Sleipnir, stepped his foot down from the heavens.

East around Snæfell, one can find wetlands and ranges, home to roaming herds of wild reindeer and abundant birdlife. Steep mountain ridges make up the south side of Vatnajökull, where outlet glaciers crawl onto the lowlands. The sandy plains of Skeiðarársandur also lie to the south, and the glacial river Skeiðará runs through this vast desert.

One of Iceland's most visited landmarks in the National Park is the Jökulsárlón glacier lagoon, which sits at the base of the outlet glacier Breiðamerkurjökull. Here, large icebergs that have broken off the glacier float across a vast lake before ending up in the Atlantic Ocean, or washed ashore on the nearby Diamond Beach.

This is one of the best seal-watching spots in the country.

The Future of Vatnajokull

The volume of Vatnajökull reached its peak around 1930 but has since been in a steady process of decline. Because of rising levels of global temperature, Vatnajökull has on average lost about a metre (three feet) of its thickness annually over the past 15 years.

If temperature levels continue to rise, the glacier could be all but gone nearing the end of the next century, leaving only small ice caps on top of the highest mountain summits.  

Efforts are being made to prevent what some say is the inevitable, with reforestation projects going on all around the glacier, a proven method of cooling the area. Time will tell how successful they are.

Vatnajokull and Jokulsarlon in Popular Culture

The beauty of Vatnajökull National Park has not gone unnoticed by those in film or television. Many famous scenes have been shot here, starting with James Bond: A View to Kill in 1985. Other notable films with scenes here include Batman Begins, Lara Croft: Tomb Raider, and James Bond: Die Another Day.

Most famously, however, many places in Vatnajökull have been used in the HBO Series Game of Thrones, north of the Wall. The Wall itself is constructed with CGI using shots of the glacier.

Gullfoss (translated to ‘Golden Falls’) is one of Iceland’s most iconic and beloved waterfalls, found on the Hvítá river canyon in south Iceland. The water in Hvítá river travels from the glacier Langjökull, finally cascading 32m down Gullfoss’ two stages in a dramatic display of nature’s raw power. 

Because of the waterfall’s two stages, Gullfoss should actually be thought of as two separate waterfalls. The first, shorter stage of the waterfall is 11m, whilst the second stage is 21m. The canyon walls on both sides of the waterfall reach heights of up to 70m, descending into the 2.5km long Gullfossgjúfur canyon (geologists indicate that this canyon was formed by glacial outbursts at the beginning of the last age.)

In the summer, approximately 140 cubic metres of water surges down the waterfall every second, whilst in winter that number drops to around 109 cubic metres. With such energy, visitor’s should not be surprised to find themselves drenched by the waterfall’s mighty spray-off. 

Gullfoss makes up a part of the highly popular Golden Circle tour, alongside Geysir geothermal area and Þingvellir National Park.

History

In the early days of the last century, Gullfoss was at the centre of much controversy regarding foreign investors and their desire to profit off Iceland’s nature. In the year 1907, an English businessman known only as Howells sought to utilise the waterfall’s energy and harboured ambitions to use its energy to fuel a hydroelectric plant.

At the time, Gullfoss was owned by a farmer named Tómas Tómasson. Tómas declined Howell’s offer to purchase the land, stating famously “I will not sell my friend!” He would, however, go on to lease Howells the land, inadvertently beginning the first chapter of Icelandic environmentalism.

It was Tómas’ daughter, Sigríður Tómasdóttir, who would lead the charge. Having grown up on her father’s sheep farm, she sought to get the lease contract nullified, hurriedly saving her own money to hire a lawyer. The ensuing legal battle was an uphill struggle; the case continued for years, forcing Sigríður to travel many times by foot to Reykjavík if only to keep the trial moving. Circumstances became so difficult that Sigríður threatened to throw herself into the waterfall if any construction began.

Thankfully, in 1929, the waterfall fell back into the hands of the Icelandic people. Today, Sigríður is recognised for her perseverance in protecting Gullfoss and is often hailed as Iceland’s first environmentalist. Her contribution is forever marked in stone; a plaque detailing her plight sits at the top of Gullfoss. 

Restaurant / Cafe

Besides Gullfoss, visitors can enjoy the views from Gullfoss Cafe, a locally run delicatessen that serves a wide variety of refreshments and meals. The menu has options to tantalise everyone’s taste buds; hot soups, sandwiches, salads and cakes. There is also a shop on site where visitors’ can browse and purchase traditional Icelandic souvenirs.

Hvannadalshnúkur, or Hvannadalshnjúkur, is the highest peak of Öræfajökull volcanic glacier in Vatnajökull National Park and the tallest mountain in Iceland. Its latest measurement finds it to be 2,109.6 meters (6952 feet) tall.

Due to the fact Iceland is located over a rift valley, where the tectonic plates are pulling apart rather that crushing together, most mountains do not reach over a thousand metres, making it a remarkable sight.

Geography of Hvannadalshnúkur

Hvannadalshnúkur is a pyramid-shaped peak, that is covered in ice throughout the year. It can be seen from many parts of the country, particularly from the area between the towns of Höfn and Vík on the Ring Road that encircles the country.

It forms part of the crater around Öræfajökull, which conceals a particularly violent volcano. It had a massive eruption in 1362, destroying many farms and killing an unknown number of people. The lava wiped out every settlement around it, all the way to the shore, and pumice was so thick that it posed a huge risk to sailors.

The area was unsettleable for decades. When people finally returned to it, forty years later, it was named Öræfi, which meant ‘the area without a harbour’. Now, it is synonymous with ‘wasteland’.

It had another, although less dramatic, eruption in the year 1727. Even if the consequences were not so widespread, glacial floods pouring from the meltwater of the ice were known to have killed at least three people and destroyed one farm.

Hiking on Hvannadalshnúkur

Hvannadalshnúkur can be hiked near, by taking routes in all different parts of the South Coast, but hiking on it requires experienced mountain guides.

The path up the mountain goes through many crevasses, and involves steep inclines over icy ground, both of which pose some dangers to those unfamiliar with the area. Though you do not need to be an expert hiker, a good level of fitness is required.

The views from the top are well worth the effort.

Other sites in Vatnajökull National Park

Vatnajökull National Park is a vast area in Iceland, and Hvannadalshnúkur is just one site that should be visited if heading to the area.

Incredibly close by are two of the country’s most popular destinations. One of these is the Skaftafell Nature Reserve. This beautiful oasis is a wonderland of glacial tongues and lagoons, crystal clear streams, waterfalls, mountains and lava landscapes.

This reserve was once an independent National Park, before the creation of the greater Vatnajökull park.

The second major site is Jökulsárlón, a vast glacier lagoon and Iceland’s deepest lake. This lagoon fills with enormous icebergs, which break from the glacial tongue of Breiðamerkurjökull and slowly cruise their way over to the ocean. This was only enveloped into the park in 2017, but now is entirely protected.

While here, it is worth walking to the nearby shoreline, called the Diamond Beach after the icebergs that wash up here.

In this area, it is very important not to climb on the ice. When afloat, it is constantly rotating, and the lagoon has shockingly strong currents. When on the beach, they are melting and unstable.

The Blue Mountains, otherwise known as Bláfjöll, are a beautiful mountain range in the south-west of Iceland. They hold some of the most popular skiing slopes in Iceland, and well as the potential for other activities such as caving and hiking.

The Blue Mountains are located around 20 kilometres (12 miles) from Reykjavík, by the lava plateau of Hellisheiði.

Geology of the Blue Mountains

The Blue Mountains partially cover the Mid Atlantic Rift, which runs through Iceland. The very regular earthquakes and sporadic eruptions, therefore, are explained the high level of geological and geothermal activity that this rift creates.

Most of the mountains are now dormant, not having erupted since the last Ice Age, but not all.

Due to their formation, the Blue Mountains are composed of tuff rock.

Activities in the Blue Mountains

As mentioned, the Blue Mountains has some of the most popular slopes in Iceland. Being so accessible from Reykjavík, just a twenty five minute drive away, the region draws those who love to ski and snowboard from the beginning of February to the end of April.

Due to these opening dates, winter sports have become somewhat of an Easter tradition for many of those living in the capital.

The resort here is the largest in Iceland, and boasts 16 ski lifts, and 15 kilometres (nine miles) of slopes. Equipment can be rented on site, and there are regular lessons taught for newcomers. Regardless of if you are a novice or expert, there are slopes for all abilities.

Cross country skiing is also very popular in the area, but should only be done by those experienced, or with a trained guide. Some snowmobilers also make the most of the opportunities the mountain provides.

Other areas for skiing in Iceland include Akureyri and Skaftafell Nature Reserve.

A popular activity that can be enjoyed in the Blue Mountains throughout the year, however, is lava caving. Due to the the volcanism of the area, the plateaus around the mountains are composed of many layers of lava rock.

When this lava first cooled, it did so from the outside in, leaving running magma beneath it. If this magma had a place to flow out to, it would form a lava cave.

Leiðarendi is a beautiful tunnel, formed in a kind of ring that allows visitors to fully explore it. Trips to Iceland’s lava caves provide wonderful opportunities to learn about the nation’s geology, history of bandits, and folklore, particularly the tolls.

This lava tube also demonstrates the volcanism of the Blue Mountains. It was, in fact, created by two seperate eruptions, one two thousand years ago and one a thousand years ago. The lava tunnels formed in each collapsed together at what is now the entrance of the cave.

Much of the area around this cave and much of the Blue Mountains is covered in a delicate moss, that creeps over the lava. When visiting any area with this unique flora, such as hiking trails through the mountains, be careful not to step on it as it is remarkably delicate

Þríhnúkagígur is a dormant volcano in west Iceland, famous for its enormous magma chamber. It is the only magma chamber in the world that can be entered, and has a depth of 213 metres (699 feet).

Formation of Þríhnúkagígur

Þríhnúkagígur was a normal volcano in Iceland’s Blue Mountain range, also call Bláfjöll. However, its last eruption, almost 2,000 years ago, had some very unusual consequences.

After an eruption, the magma chamber of a volcano, now free of pressure, usually remains full of lava that cools into solid rock until the next eruption. If the magma chamber is fully emptied, the volcano will usually collapse in on itself.

To the bewilderment of scientists, however, neither of these things happened to Þríhnúkagígur.

It seems that a rift beneath the chamber drained it of all remaining lava, leaving behind an enormous chamber, that covered an area of 3,270 square metres (35,200 square feet). To give some idea of the scale of this, the Statue of Liberty could stretch her limbs within it, and it could comfortably fit Hallgrímskirkja church.

Unusually, the volcano did not collapse, and it has remained unchanged since.

Discovery and Exploration of Þríhnúkagígur

The vast magma chamber under Þríhnúkagígur would not be discovered until 1974, by an Icelandic cave explorer. Its discovery made world news, as volcanologists had not seen anything like it before, and were fighting to try to explain its existence.

In 2012, it was opened for tourism. A lift, akin to those used in mining, was installed, and visitors were now allowed to join tours plumbing its depths.

Its popularity comes not only from the uniqueness of the tour and the scale of the chamber, but the incredible colouration within it. Mineral deposits dye the walls vivid shades of red, yellow, green and blue, making the incredible space that much more ethereal.

Reaching Þríhnúkagígur requires a short but uphill hike, which can be done by any steady on their feet with a reasonable level of fitness. Tours only operate in summer.

The mighty Langjokull (“The Long Glacier“), in the midwest highlands is the second-largest glacier in Iceland, at 935 km2. For jeep and snowmobile trips, Langjokull is the most popular glacier in Iceland and skiing and hiking is possible as well. We stress that under no circumstances should one travel alone on Langjokull, as there are many cracks in the glacier. Experience of the area, whether that of yourself or of those traveling with you is all important.

Highland tracks

Two main highland tracks, connecting the north and the south, lie alongside the glacier, Kaldidalur road and Kjalvegur (a.k.a. Kjolur road). The Kaldidalur road stretches from Thingvellir northwards to Husafell (in Borgarfjordur district), between Langjokull and Ok shield volcano. Kjalvegur lies east of Langjokull and west of Hofsjokull glacier, starting near the famous Gullfoss waterfall to the south and the Svartakvisl stream by the Hveravellir geothermal area to the north.

The Landscape of Langjokull

Langjokull is about 50 km long and 15-20 km wide. The volume of the glacier is 195 km3 and the ice is around 580 m thick. The glacier reaches its highest point at the northernmost part of the glacier, which is called Baldjokull, rising around 1450 m above sea level.

Counting west and southwards from there, outlets extending from the main glacier are Thristapajokull, Flosajokull, Geitalandsjokull, Flosajokull, Geitlandsjokull and West- and East Hagafellsjokull furthest south, separated by Mt. Hagafell. On the eastside from north to south are Leidarjokull, Kirkjujokull, Nordurjokull, and Sudurjokull.

The glacier lies over a massif of hyaloclastite mountains that rise highest in the south and the east. The tops of these mountains can be seen in certain places on the glaciers. To the northeast are Hyrningur (1320 m), Peturshorn (1358) m), Fjallkirkja (1248 m) and Thursaborg (1315 m), a mighty series of immense rock pillars rising high to the sky. In the southern part of Langjokull, between Lonsjokull and Vestri-Hagafellsjokulll is the 995 high Klakkur.

Notable nearby mountains

The main mountains that lie close to Langjokull to the north are Krakur and the Burfjoll mountain range, slightly eastwards. East of Baldjokull are Hafjall and the Thjofadalafjoll mountain range. Hrutfell with the Hrutfellsjokull glacier cap (1396 m) lies east of Fjallkirkja and is the most impressive mountain of the Kjolur area, along with Kjalfell (1008 m), further northeast.

On the south eastern side of Langjokull, between the outlets Nordurjokull and Sudurjokull lies Mt. Skridufell (1235 m) and south of Sudurjokull is the shield volcano Skalpanes. Further east, i.e. south of Hvitarvatn is the 1204 m high Blafell and south of Skalpanes is the impressive palagonitic mountain range Jarlhettur. Among the most prominent mountains south of the Langjokull glacier is Hlodufell at 1186 meters and the Skjaldbreidur shield volcano further east.

Among the most prominent mountains to the west of Langjokull are Hafrafell,  south of Eiriksjokull,  North- and South Hadegisfell, Ok volcano, Prestahnukur volcano, and Stora- and Litla Bjornsfell.

Nearby glaciers

Glaciers located near to Langjokull are Eiriksjokull, to the west, the highest mountain of West Iceland, and Thorisjokull, further southwest. Hrutfellsjokull lies on the east side of Langjokull.

Between Thorisjokull and Geitlandsjokull is a valley called Thorisdalur. Along with stunning views it features prominently in Icelandic folk tales and the outlaw Grettir the strong of Grettis saga fame is further reported to have resided there for one winter.

Glacier-fed rivers & lakes

Two glacier rivers, both bearing the name of Hvita (‘White River’) trace their sources to Langjokull. The first is the mighty Hvita in Arnessysla county, home to Iceland‘s most famous waterfall, Gullfoss, the beautiful Bruarhlod canyon and one of Iceland‘s most popular rafting rivers. The source of this river is Hvitarvatn lake, east of Langjokull. The outlet Nordurjokull reaches the lake and lends it a distinctly glacial colour. Sudurjokull used to reach it as well but has retreated in recent times.

The other Hvita glacier river, in Borgarfjordur, also has its source in the area, by Eiriksjokull glacier. In this river are the beautiful waterfalls Hraunfossar and Barnafoss. Indeed, many of the hot springs in Borgarfjordur receive ground water from Langjokull. Sub-surface water also flows south to Lake Thingvallavatn, reappearing in springs in and around the lake. A few rivers flowing north to Hunafloi bay also have their sources there.

To the south, Eystri-Hagafellsjokull feeds a lake called Hagavatn and several smaller river flow from there to lake Sandvatn. In turn, rivers flow from this lake to two major rivers i.e. Hvita in Arnessysla  & Tungufljot. Tungufljot later joins up with Hvita and Hvita itself merges with Sogid river as Olfusa and this river then flows towards the sea.

Volcanism

There are at least two active volcanic systems under Langjokull glacier, whose calderas are visible from the air. The best known of these is the geothermal area of Hveravellir, east of Baldjokull. Also to the east lies the Kjalhraun lava field, which flowed about 7800 years ago.

To the northwest of the glacier is another system that produced the vast Hallmundarhraun lava field, through which Hvita in Borgarfjordur runs, with its stunning falls. Also in the area is Iceland‘s longest lava cave, the fascinating Surtshellir.

Southwest of Langjokull is the Presthnukur lava field, its fissures extending under Langjokull. South of the glacier is the Lambahraun lava field and further east, i.e. south of Thorisjokull, lies the Skjaldbreidarhraun lava field and the Skjaldbreidur  shield volcano.

Compared to other regions in Iceland, the area is considered relatively calm, with only 32 eruptions in the last 10.000 years.

Global warming

Langjokull is shrinking fast and concerns have been raised about the glacier due to the effect of global warming. Some researchers feared that if climate change continues at its current rate the glacier may be gone in about 150 years.
