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.

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)

• 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.

Breiðamerkurjökull is the glacial tongue that extends from southern Vatnajökull and into the glacier lagoon Jökulsárlón, creating the icebergs that define this beautiful landmark.

Breiðamerkurjökull is constantly retreating, breaking and melting, causing the Jökulsárlón glacier lagoon to increase in size; it is less than a century old, but already the deepest lake in Iceland.

This glacier tongue provides the lagoon with all of its enormous icebergs, which perpetually break from off its tip and tumble into the waters. Here they float for about five years until they are small enough to make their way towards sea. When they finally do escape the lagoon, most join the countless smaller ice chunks that adorn the nearby Diamond Beach.

Breiðamerkurjökull is beset with enormous cracks and crevices, and since it's virtually impossible to tell exactly when the next big block of ice will break from it, people should admire this enormous glacier tongue from a great distance.

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.
