Jökulsárlón is Iceland’s most famous glacier lagoon. Conveniently located in the southeast by Route 1, about halfway between the Skaftafell Nature Reserve and Höfn, it is a popular stop for those travelling along the South Coast or around the circular ring road of the country.
Geography
As a glacier lagoon, Jökulsárlón is a lake that is filled with the meltwater from an outlet glacier. In this case, it is Breiðamerkurjökull, a tongue of Europe’s largest ice cap, Vatnajökull.
It stands out, however, due to the fact that it also fills with icebergs breaking from the glacier, some of which tower several stories high.
These icebergs, other than their scale, are notable for their colouration. Although they are, as expected, largely white, most are also dyed electric blue in part, with black streaks of ash from eruptions centuries past.
When the icebergs finally make it across the lagoon, they either drift out to sea or wash up on the nearby shore. Because of the way they glisten against the black sands of Breiðamerkursandur, this area has been nicknamed ‘the Diamond Beach’.
In spite of being a rather recent formation, Jökulsárlón is the deepest lake in the country, with depths reaching 248 metres. With a surface area of 18 square kilometres, it is also growing to be one of the largest.
History
Jökulsárlón has not been around since Iceland’s settlement; it only formed around 1935. This was due to rapidly rising temperatures in the country from the turn of the twentieth century; since 1920, Breiðamerkurjökull has been shrinking at a dramatic rate, and the lagoon has begun to fill its space.
Today, the expansion of Jökulsárlón is accelerating. As recently as 1975, it was just 8 square kilometres, and now that size has more than doubled.
In the relatively near future, it is expected that the lagoon will continue to grow until it becomes a large, deep fjord.
Though a dark omen for Iceland’s glaciers and ice caps in general, the retreat of Breiðamerkurjökull has resulted in an incredibly beautiful, if temporary, site. This has not been overlooked by Hollywood.
Jökulsárlón has been featured in the James Bond films A View to Kill in 1985 and Die Another Day in 2002, 2001’s Lara Croft: Tomb Raider, and 2005’s Batman Begins.
In 2017, Jökulsárlón was enveloped into the Vatnajökull National Park, thus it is now fully protected by Icelandic law.
Wildlife
Because of the wealth of herring and capelin that the tides bring into the lagoon, Jökulsárlón is somewhat of a hot-spot for Iceland’s wildlife.
In summer, it is a nesting site for Arctic Terns; stay well away from this area, as these birds are notorious for the fierceness with which they protect their eggs, dive-bombing the heads of any they see as a threat. Skuas also nest on the lake’s shores in this season.
Seals can be reliably spotted here throughout the year, swimming amongst or else hauling out on the icebergs. Jökulsárlón provides them with a safe haven to rest and socialise, especially considering the waters of southeast Iceland are renowned for their population of orcas.
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)

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.
Solheimajokull is a beautiful outlet glacier of the Myrdalsjokull icecap.
Solheimajokull is a rugged glacial tounge riddled with crevasses and spectacular ever-changing ice formations, jagged ridges and sinkholes and is popular for hiking and ice climbing.
The glacier river Jokulsa a Solheimasandur has its source at the glacier, flowing over the sand plain of Solheimasandur towards the sea.
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:
‘The time for Katla to erupt is coming close… it is high time for European governments and airline authorities all over Europe and the world to start planning for the eventual Katla eruption’
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
