Nestled between the glaciers Eyjafjallajökull, Mýrdalsjökull, and Tindfjallajökull is Þórsmörk, the Valley of Thor. A nature reserve in the southern Icelandic highlands, Þórsmörk is one of the country's most popular hiking destinations and a favourite location for photographers and nature lovers alike.
Strictly speaking, Þórsmörk is a valley and a mountain range between the Krossá, Þröngá, and Markarfljót rivers.
Locals, however, often use the name ‘Þórsmörk’ when referring to a much larger region that is composed of the area between Þórsmörk proper, and the Eyjafjallajökull glacier volcano, the peak that notoriously erupted in 2010 and caused widespread disruption to air traffic in Europe.
Landscapes and Geology
The contrasting vistas of lush oases and roaring glacier rivers cutting through black desert expanses not only make Þórsmörk unique in Iceland but to the entire world. Parts of the valley are rich with moss, fern, and birchwood, while jagged mountain ridges and ice-capped peaks crown the horizon.
The valley's climate is warmer and calmer than usual in south Iceland, which often causes Þórsmörk's mountains to be cloaked in a veil of mist that materialises when the warm valley air ascends and mixes with the descending cold breath of the glaciers above. This is due to the colossal peaks that both surround and shelter it.
In spite of being warmer, Þórsmörk is also wetter than the rest of the country. This, however, only brightens the vegetation, giving the area a lush, emerald hue.
Activities
Þórsmörk's surrounding hills, slopes and mountains are beset with small valleys and gullies that make for some of Iceland's most astonishing hiking routes.
Experienced hikers, therefore, have a wealth of trails to trek, varying in distances and difficulty. In fact, Þórsmörk offers two of the most popular trails in Iceland, the Fimmvörðuháls and the Laugavegur routes.
Fimmvörðuháls is a 30 kilometres (19 miles) trail that takes you into the hills beneath the Eyjafjallajökull glacier volcano and to the volcanic craters Magni and Móði, which erupted during the 2010 eruption. You can feel the lingering effects of the volcano by feeling heat still rising from the lava rock.
The 55 kilometre (34 miles) Laugavegur path takes you from Þórsmörk to the Landmannalaugar geothermal area, which is home to an incredible wealth of hot springs and rhyolite mountains of vibrant colours.
A short but demanding hike from Þórsmörk up Mt. Útigönguhöfði is suitable for those who are looking for stunning views and don't mind a little physical challenge.
Accommodation and How To Get There
During winter (October 16th to April 30th) the road into Þórsmörk is impassable. In summer (May 1st to October 15th) a special four-wheel-drive mountain bus runs three times per day from the BSÍ bus terminal in central Reykjavík.
Once there you have the choice of setting up base in a small hut in Húsadalur valley, a private room or a dormitory in Langidalur valley, or to camp in Þórsmörk's campsite. Please note that the huts, private rooms and dormitories must be booked well in advance.
Of course, when the roads are clear, it is possible to drive there yourself. As with all cases with driving in Iceland, however, ensure that you are comfortable with the vehicle you have and your driving skills before setting off.
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...
