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 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 of 248 metres (814 feet). With a surface area of 18 square kilometres (7 square miles), 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. In 1975, it had less than half its current surface area.
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 their nesting 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.
Skaftafell is a nature reserve located in Vatnajökull National Park in the south-east of Iceland. It is an oasis of this nation’s diverse landscapes and features, so beautiful it was once a national park in its own right.
Nature of Skaftafell
Skaftafell is notable for its rich flora, growing between sands and glaciers, and for its amazing, contrasting scenery. Visitors will find a wealth of natural attractions, from cascading waterfalls to glacier lagoons, geological formations to black sand deserts.
The rugged region is known for its fantastic photo opportunities, with many awe-inspiring panoramic views.
Like many areas along the South Coast of Iceland, Skaftafell Nature Reserve is known for its glorious hiking trails, often called a ‘hiking paradise’. Unlike in the Highlands, where hikes tend to go on for multiple days, here there are far shorter. There are easy treks that lead to diverse sites such as the waterfall Svartifoss which is surrounded by bizarre and beautiful basalt columns, as well as to glaciers such as Svínafellsjökull.
With a qualified guide, it is an excellent region to try your hand at a spot of either ice climbing or glacier hiking; both activities are two of the most authentically Icelandic experiences you can partake in whilst in the country.
The nature reserve is also the perfect base camp for those seeking to climb Iceland’s highest peak, Hvannadalshnúkur, or for those wishing to spend a number of days exploring the region's attractions, including Vatnajökull glacier, Jökulsárlón glacial lagoon and the nearby Diamond Beach.
Getting to Skaftafell
Just off the Ring Road in the south-east of the country, it takes approximately four hours to reach Skaftafell from Reykjavík. The South Coast, however, is one of the regions most popular sightseeing routes, so the journey usually takes much longer, as visitors will want to make several stops along the way.
Examples of the beautiful natural features found en route to Skaftafell include the waterfalls Seljalandsfoss and Skógafoss, the glaciers Mýrdalsjökull and Eyjafjallajökull, the black sand deserts of Sólheimasandur and Skeiðarársandur, as well as the dramatic coastal rock formations at Dyrhólaey and Reynisdrangar. The villages of Vík and Kirkjubæjarklaustur are also along Route 1 if you need to stop and refuel on refreshments.
Those who have made it all the way to Skaftafell will want be sure to check out the Jökulsárlón glacier lagoon, a giant lake filled with enormous icebergs breaking from a glacial tongue, and slowly drifting to sea. At the nearby Diamond Beach you can watch them wash upon the shore, and in both the sea and lagoon are many seals which can routinely be spotted.
Skaftafell Visitor Center
You will find a Visitors Centre at Skaftafell which acts as the main information and meeting point for tour operators and independent travellers. At the Skaftafell Visitor Centre, you will find answers to virtually any questions you might have about the greater Skaftafell area, including its history and geology. The Visitors Centre also contains information about nearby hiking trails, recreational options and accommodation.
There is also a hotel at Skaftafell, though it tends to book up very early. Luckily, the south-east is dotted with hotels, cabins and cottages in which you can stay, and the area is not far from the settlements of Höfn or Kirkjubæklaustur.
