하이라이트: 
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 Icelandic Highlands cover the majority of the country and many of Iceland’s impressive natural attractions can be found here. Away from crowds, noise and bustle, the Highlands offer silence, serenity, peace and extreme natural beauty.
A favourite amongst hikers and photographers, the Highlands are accessible from June to September.
The Central Highlands
The Central Highlands cover a vast area, at an altitude of over 500 metres (1640 feet), with numerous mountains reaching heights between 1,000 and 2,000 metres (3,281 and 6562 feet). Most of these higher mountains are covered by glaciers.
The tallest mountain in the country is located in the Highlands, beneath Europe’s largest glacier, Vatnajökull. Hvannadalshnúkur stands at an incredible 2,109 metres (6,919 feet) tall and can be reached on some helicopter tours. Another notable peak is Bárðarbunga, a sub-glacial volcano in northwest Vatnajökull that stands at 2,000 metres.
Vatnajökull is the greatest of the three largest glaciers in the country, all of which are in the Central Highlands; the others are Hofsjökull in the centre of Iceland and Langjökull, west of Hofsjökull.
Various highlands paths lie between the glaciers. These usually open in June, but late snows have been known to push the opening to July. One of the major routes is Kjölur, which connects the south and north of Iceland. It is located between Hofsjökull and Langjökull and passes through a region of rhyolite mountains and geothermal oases.
Sprengisandur, is another noteworthy path connecting the south and north, and it is located between Hofsjökull and Vatnajökull.
Kaldidalur is also a significant highland road stretching west of Langjökull, from Þingvellir towards the Borgarfjörður district.
Always remember that the natural environment that makes up Iceland's Highlands is as delicate as it is enchanting. The slightest damage inflicted upon small areas can cause erosion and irreversible landscape wounds that can easily spread over large areas. Consequently, when travelling in the Highlands visitors must at all times uphold responsible travel etiquette.
Driving off-road and designated paths is strictly forbidden and punishable by heavy fines. The moss is delicate and should not be walked or camped on, let alone removed, and fishing is heavily regulated.
The South Highlands
Almost all the mountains south of the glaciers are tuff mountains, formed during the Ice Age. Volcanic activity is confined to tuff areas of the country and the southern Highlands are home to some of Iceland's most active volcanoes: Hekla, Eyjafjallajökull and Katla, which sits under Mýrdalsjökull, Iceland’s fourth largest glacier
Eyjafjallajökull is the most famous of these volcanoes. When it erupted in 2010, it caused major disruption to air travel across Europe, and widespread confusion to newsreaders everywhere as they tried to pronounce it; it was thus nicknamed to E11.
The South Highlands is also home to Landmannalaugar, one of the country's best hiking and hot spring bathing sites.
Northeast, Central-North and Northwest Highlands
In the northeast of the Highlands are the Lakagígar Craters the famous subglacial lake and volcano, Grímsvötn, and the glacier Öræfajökull. North of Vatnajökull, the best-known volcanoes are Askja and Krafla.
Also in this area is the Jökulsárgljúfur canyon, which holds the most powerful waterfall in Europe, Dettifoss.
The northwest and central-north Highlands consist of ancient basalt formations, similar to the mountains that comprise the Eastfjords.
Highland Oases
There are a few oases in the highlands that have unique vegetation and wildlife. The most important of these are Þjórsárver, Nýidalur/Jökuldalur, Herðubreiðarlindir and Eyjabakkar. The pink-footed goose has its main nesting places at Þjórsárver and Eyjabakkar. Þjórsárver was designated as a Ramsar site in 1990.
Wild reindeer reside in the east Highlands; this is the only place they can be seen. Initially brought over for farming, the industry never took out and they have roamed free in their herds since.
Landmannalaugar, or the 'People's Pools', is a vast area of stunning and unique beauty in the heart of Iceland's southern Highlands. Throughout the summer, it is one of the most popular places for hiking -- either over one day or several -- and natural hot spring bathing.
Geology
Landmannalaugar is a truly rare area, both geologically and aesthetically. The dramatic region can be found nestled beside the raven-black Laugahraun lava field, a sweeping expanse of dried magma which originally formed in an eruption in 1477.
Landmannalaugar itself is made up of windswept rhyolite mountains, a rock type that creates a full spectrum of dazzling colour. Shades of red, pink, green, blue and golden yellow make for an ethereal location.
Landmannalaugar was historically best known for its natural geothermal baths, hence its name the People's Pools. For centuries, it served as an area of shelter and respite for weary travellers who use these soothing springs as a means to relax after tiring excursions.
Originally, those attending were settlers crossing the barren highlands, but today, they are tourists after an exciting trip.
Today, visitors to the Highlands should always bring a swimsuit and towel, just in case one of these naturally occurring hot pools should crop up along the hiking trail.
The most popular road leading to Landmannalaugar, Sigölduleið, has such springs, and takes you past multiple stunning natural features, including Bláhylur lake, a magnificent body of water nestled in a dormant volcanic crater.
Landmannalaugar can be reached by car in one of two ways. The quickest is driving through West Iceland, either via Selfoss or Þingvellir National Park. A longer but more scenic route would take you along the South Coast of Iceland. This is Iceland’s most popular sightseeing route, aside from the Golden Circle, due to its wealth of sites.
Of course, like many of Iceland’s destinations, Landmannalaugar can also be reached via helicopter, for those who are travelling with less of a concern for budget. Those on more of a shoestring can buy a bus pass that will take them to the region.
Hiking
Landmannalaugar marks the northern end of the Laugavegur, one of Iceland's most popular hiking trails. This route connects Landmannalaugar and Þórsmörk, the ‘Valley of Thor’, ending at the beautiful Skógafoss waterfall.
It is also home to many other notable trails, however, including the path onto the mighty Mt. Brennisteinsalda, the ‘Sulphur Wave’ crater. Visitors can also traverse the trail up the Bláhnjúkur volcano, the 'Blue Peak', whose summit allows for a sweeping view of up to five glaciers on clear days.
Multiple operators run daily tours to Landmannalaugar from mid-June to mid-September, during which time the Icelandic Touring Association operates a small shop, three campsites and a mountain hut equipped with sleeping bags and accommodation for up to 80 visitors.
It is only recommended you take a multi-day hike with an operator. If visiting Landmannalaugar without a guide, you will need a four-wheel-drive.
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.
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...
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 throughout the year, 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
Laugavegur is one of the most popular highland trails in Iceland. The scenery is breathtaking in its beauty and diversity, perfectly representing the country’s raw natural wonder.
The area is a favourite for those who want to take multi-day hikes through the Icelandic Highlands.
The Laugavegur Highland Trail should not be confused with the Laugavegur shopping street in Reykjavík. The name Laugavegur means ‘the way of the water’.
Location of the Laugavegur Hiking Trail
The Laugavegur Trail is located in the southern Icelandic Highlands, and connects the geothermal area of Landmannalaugar to the forested valley of Þórmörk.
Landmannalaugar is a spectacular location, only accessible in summer, renowned for its colourful rhyolite mountains and bubbling hot springs, which guests are welcome to bathe in.
Þósmörk, meanwhile, is sheltered by mountains and glaciers, and famous for its greenery. It is so beautiful that it was named after the most acclaimed of the Old Norse Gods, Þór (often anglicized to Thor).
The Laugavegur Trail, from Landmannalaugar, passes the ‘Swan Lake’, Álftavatn; the black sand desert of Mælifellssandur, renowned for its vibrant green mountain Stórasúla; and through the plains of Emstrur. There are countless peaks, crater lakes and volcanoes en route, and the trail sits in the shadow of the glaciers Mýrdalsjökull and Eyjafjallajökull.
It is 55 kilometres (34 miles) long.
Hiking the Laugavegur Hiking Trail
The Laugavegur Hiking Trail is one of the most popular hiking routes in the country. It is usually taken over five- to six- days, although some tours have an additional day hiking the Fimmvörðuháls Pass from Þórsmörk to Skógafoss waterfall. The route can usually be accessed from June to September, though this is weather dependent.
It is possible to camp as you cross the Highlands via the Laugavegur Trail, but most tours stop off at the mountain huts of Hrafntinnusker, Alftavatn, Hvanngil, Laugahraun and Emstrur (Botnar).
Hiking the Laugavegur Trail should only be done by those with good endurance, as many of the paths are uphill, and the days can be quite long. If you wish to hike it without a guide, you must be an expert, well-researched hiker, with all necessary equipment and stocks, and way to contact emergency services as a precaution.
It is also highly recommended that you register your journey at safetravel.is, so that the rescue teams will be alerted if you do not get to your destination at your expected time.
Though some may wish to take the tour independently, there are many advantages to joining a group. It is safer; you will also have the company of an experienced, knowledgeable guide who can tell you about the locations you pass through; your heavy bags will be taken ahead of you; and you don’t need to worry about bringing or cooking food.
Regardless of if you are hiking yourself or on an organised tour, you will need many layers of warm, waterproof clothing; shoes for crossing rivers; sturdy hiking boots with ankle support; a first-aid kit; and a large water bottle.
It is also highly recommended that you take a camera, as well as a swimsuit and towel to enjoy the hot springs at Landmannalaugar.
