Sólheimajökull is an outlet glacier of the mighty icecap of Mýrdalsjökull on the South Coast of Iceland. It is one of the most easily accessible glaciers to reach from Reykjavík, just 158 kilometres (98 miles) away.
For those who are based in Reykjavík, it is by far the favourite spot on which to take guided glacier walks, competing nationally for popularity only with Svínafellsjökull in the south-east.
Geography of Solheimajokull
About eight kilometres long and two kilometres wide (five miles long and just over a mile wide), Sólheimajökull is an impressive feature. Due to the way it descends from Mýrdalsjökull, however, without a clear distinction between the two, it appears much bigger.
Mýrdalsjökull itself has many other outlet glaciers; overall, it is the fourth largest ice cap in Iceland. Beneath its thick surface is one of the country’s most infamous volcanoes, Katla.
The nearby Eyjafjallajökull erupted in 2010 causing widespread havoc at European airports. Throughout history, eruptions in Eyjafjallajökull mean that Katla will also erupt, and so the volcano is due to go off soon. However, volcanoes and all seismic activity in Iceland is highly monitored, meaning that it is perfectly safe to travel around the area and even take an ice cave tour in the glacier above.
Sadly, like all the glaciers in Iceland bar one, Sólheimajökull is shrinking rapidly. A glacier lagoon at its base reveals how quickly it is receding: the length of an Olympic swimming pool every year. It seems like this change is already an irreversible consequence of climate change, and it may be gone within decades.
Visitors to Iceland should, therefore, make sure they witness the ice-cap while it is still with us.
Sólheimajökull has several distinctive traits that separate it from other glaciers. Firstly, it is incredibly easy to find, laying just off of the Ring Road that encircles Iceland. Secondly, it is not surrounded by tall mountains, meaning those who ascend it can attain incredible views of the South Coast. Thirdly, it is home to many walls of ice that can be climbed up with ice axes on certain tours.
There are also crevasses that snake across the surface, spectacular ice ridges and formations, and a vivid colouration that dances between a gleaming white, electric blue, and ash black. Occasionally, you will even find an ice cave, though these can never be guaranteed.
A river runs from the meltwater of the glacier tongue, called the Jökulsá á Sólheimasandi. This river runs through a glacial outwash plain - otherwise known as a black-sand-desert - of Sólheimasandur to the nearby ocean.
Tours on Solheimajokull
Many day tours run from Reykjavík to Sólheimajökull, for glacier hikes or as part of a greater South Coast tour.
Greater South Coast tours include visits to other features, such as the incredible waterfalls of Skógafoss and Seljalandsfoss, the black sand beach Reynisfjara, and some even reach Vatnajökull National Park and the Jökulsárlón glacier lagoon.
Hidden crevasses and ice caves, slippery surfaces, and the threat of rock- or ice-falls all pose dangers on glacier hikes, but glacier guides have to pass several training courses to deal with these eventualities, making the activity quite safe for those in a fit state of health.
All guests are equipped with helmets, ice axes, and crampons, and should arrive wearing warm clothes and sturdy hiking boots.
It is forbidden to ascend glaciers without the correct equipment or training, for your safety and the safety of others. There have been injuries and deaths on Sólheimajökull before, and glacier guides have had to risk their lives to rescue those who flouted the rules.
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
