Highlights: 
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.
The Westman Islands, or Vestmannaeyjar, are an archipelago of 15 islands and 30 rock stacks off the South Coast of Iceland. Aside from their incredible natural beauty, the islands have the world’s largest population of nesting puffins in summer, and a fascinating history.
History of the Westman Islands
The history of the Westman Islands is as dark as it is intriguing, beginning at the very start of Iceland’s history, with the first family to settle here.
The first person renowned for permanently settling Iceland was a man called Ingólfr Arnarson (although it should be noted that he hardly came alone; he was accompanied by his wife Hallveig Fróðadóttr and several slaves). His half-brother joined him in the country, a few years later, but met his death at the hands of two of his own captured men.
These slaves attempted to flee and hide, to escape Arnarson’s vengeance. They reached the Westman Islands, but unfortunately, were found by ‘Iceland’s father’ and killed in retribution.
The islands since have been named after these men; they were Irish slaves, and at the time, the Irish were called ‘Westmen’, as Ireland was thought to be the westernmost landmass before Iceland’s discovery.
This brutal beginning would be a hint at the later events to occur on and shape the archipelago.
The largest island, Heimaey, was settled in the early era, and the people on it lived off the fertile oceans, puffins, and eggs. Life was challenging but manageable, until a terrible tragedy occured in 1627.
At the height of the Ottoman Empire, it was Barbary Pirates from Algiers who ruled the seas, and they managed to find their way to this little island. They took control of it for three days, before setting off back home with 237 slaves.
The vast majority of these lived out the rest of their lives in bondage, though some were ransomed back in 1638.
The trials of the voyage and their captivity was captured in a novel by a priest who managed to escape in 1628.
Unfortunately, this was not the last major calamity to befall the islands.
In the 20th Century, it seemed that the Westman Islands had overcome their hardships, modernising and better connecting to the mainland. That, however, was to be overturned in 1974.
At 01.55, on January 20th, a fissure tore open in the middle of the town of Heimaey and the previously unknown Eldfell volcano began to violently erupt. In hours, it had torn across the island, spurting fountains of lava height in the air and pouring noxious gasses into the atmosphere.
Unbelievably, however, no-one was killed. There was an emergency plan for a situation such as this, and thankfully, storms the days before meant that the whole fishing fleet was docked in the harbour. The entire population of the island was taken to safety.
That is not to say, however, that the work was done. 5,300 peoples’ homes were in the town, and the Icelandic authorities were desperate to do what they could to help protect them. At the time, the US had a NATO base in the country, and their help was enlisted.
By pumping seawater onto the great lava fronts, it was possible to cool the molten rock, slow it, and change its direction.
This innovative, previously unused technique was particularly effective when it came to protecting the harbour. It seemed at one point that the eruption may have closed it entirely, effectively destroying the island’s economy, yet by spraying the lava, the harbour was actually enclosed more and improved.
When the eruption ended, the island slowly repopulated to about 85 percent of its previous population; about one fifth of the buildings were destroyed.
The town, however, now had a long stretch of new land to build a runway on, and a volcano in its centre to draw guests. Ever since, the Westman Islands have recovered as a popular tourist destination.
The Westman Islands today
Today, the Westman Islands attract thousands of visitors of years, for a variety of reasons. Many wish to visit the Eldborg crater and learn about the eruption in depth at the Eldheimar Museum. Others come for the incredible nature opportunities.
First and foremost amongst these are the chances for puffin watching. Ten million puffins nest in Iceland between May and September, and more of them come to the Westman Islands than anywhere else.
They nest in the cliffs, crags and sea-stacks, and can be easily seen by travelling on foot or by boat. Towards the end of the season, many of the pufflings get confused by the lights of the town as they try to make their way to the ocean, and end up in the streets; it is thus a local tradition amongst the children to collect them and throw them in the sea.
Some business-savvy young ones used to even collect them up, and ‘sell’ them to tourists to release.
The puffins are just one of the thirty or so species that nest on the islands, but by far the most abundant.
The Westman Islands also boast some of the best whale-watching opportunities in the country, with Fin, Minke and Humpback Whales seen often in summer, and Orcas throughout the year.
Getting to the Westman Islands
The ferry Herjolfur sails to the Westman Islands from the town of Þorlákshöfn, on the south shore of Iceland. In poor conditions, another ferry leaves from the town of Hvolsvöllur. It is also possible to fly there from Reykjavík Domestic Airport.
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...
Gljúfrabúi (or Canyon Dweller) is a beautiful waterfall located at Hamragarðar in South Iceland, close to its better known counterpart, Seljalandsfoss waterfall. It is one of the hidden gems of the South Coast, and thus a great spot for photographers and those seeking to admire nature in peace.

Nature of Gljúfrabúi
The 40 metre (131 feet) high Gljúfrabúi is hidden behind a huge cliff which faces out towards Iceland’s South Coast and the Atlantic Ocean. Because of its decent ‘hiding place’, it is overlooked by most travellers, in spite of the fact that thousands of people visit Seljalandsfoss, less than a kilometre away, every day.
A stream, the Gljúfurá, runs through a cleft in the cliff, and those who wish to approach the falls must do so by wading through these waters.
After a few metres of travelling through a narrow valley, the space will open, and here, Gljúfrabúi tumbles before a great boulder, which it is possible to climb upon for some great photos. With the open sky above, mossy walls, silver mist and black lava, it is one of Iceland’s most breathtaking gems, seemingly from a fantasy story.
This is especially the case on sunny days, where rainbows curve through the water’s spray.
It is also possible to see Gljúfrabúi from above. There is a steep path that allows you to clamber up the cliff, at some points with the aid of ropes.
Both these routes are mildly challenging and have their dangers, so only attempt to reach Gljúfrabúi if you are in a decent state of health and confident on your feet. They should only be attempted when there is not ice on the ground, and in the case of the path up the cliff, when it is wet and slippery.
Surroundings of Gljúfrabúi
Gljúfrabúi is in one of the most travelled regions of Iceland, on the South Coast along the Ring Road. This means that it is very easy to reach, either alone or on a guided tour, just an hour and a half’s drive from the capital.
As mentioned, Gljúfrabúi is about ten minutes walk north Seljalandsfoss. Interestingly, this is one of the country’s most famous and photographed waterfalls, due to the fact it falls from a concave cliff which allows visitors to fully encircle the cascade.
Seljalandsfoss is taller than Gljúfrabúi at 60 metres (196 metres), with a similar waterflow. Both are fed by the meltwater of the glacier Eyjafjallajökull, the volcano beneath which caused widespread problems to air traffic across Europe when it erupted in 2010.
A much more powerful waterfall can be found just half hour’s drive or so along the Ring Road, called Skógafoss. This is a similar height to Seljalandsfoss, but up to 30 metres (98 feet) wide after a heavy rain.
Another popular site in the area is Sólheimajökull, the most popular glacial outlet in Iceland for glacier hiking. This feature is on Sólheimasandur, a vast expanse of volcanic ash that resembles a black sand desert.
Those who travelling a little further along the South Coast will reach the cliffs of Dyrhólaey, with their beautiful rock arch and resident puffins in summer, and the beach of Reynisfjara, renowned for it powerful waves and basalt sea-stacks, called Reynisdrangar.
All these sites can be visited with ease within a day.
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.
