Obszar: 
The Icelandic Highlands cover the major part of the country and many of Iceland’s main natural attractions can be found there. Away from crowds, noise and bustle, the Highlands offer unique silence, serenity, peace and extreme natural beauty.
The Central Highlands
The Central Highlands cover a vast area, all at an altitude of over 500 meters, with numerous mountains reaching a height between 1000 and 2000 meters. Most of these higher mountains are covered by glaciers. Two of the highest mountains in the country (over 2000 m high) are located in Vatnajökull, namely Hvannadalshnúkur (2109 m, located in south Vatnajökull) and Bárðarbunga, a subglacial volcano in northwest Vatnajökull (2000 m).
Three of the largest glaciers in Iceland are located in the Central Highlands. These are Vatnajökull in the southeast (Europe’s largest glacier), Hofsjökull in the centre of Iceland and Langjökull, west of Hofsjökull.
Various highlands paths lie between the glaciers, open for cars around June/July. One of the major ones are Kjölur, connecting south and north Iceland (the road is located between Hofsjökull and Langjökull). Sprengisandur, is another important path, connecting south and north, and located between Hofsjökull and Vatnajökull.
Kaldidalur is a highland path stretching west of Langjökull, from Þingvellir towards the Borgarfjörður district. It then continues further north as Stórisandur.
Remember always 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. When travelling in the Highlands, therefore, visitors must at all times uphold responsible travel etiquette. Driving off roads and designated paths is strictly forbidden and punishable by heavy fines.
The South Highlands
Almost all the mountains south of the glaciers are tuff mountains. They were formed during the Ice Age, as well as the area north of Vatnajokull. Volcanic activity is confined to tuff areas of the country and in the southern Highlands are some of its most active and famous volcanoes, Hekla, Eyjafjallajökull and Katla in Mýrdalsjökull, Iceland’s fourth largest glacier.
Northeast, Central-North and Northwest Highlands
To the northeast are the Lakagígar Craters and in Vatnajökull there are Grímsvötn and Bárðarbunga along with Öræfajokull. North of Vatnajökull, the best-known volcanoes are Askja and Krafla.
The northwest and central-north Highlands consist of ancient basalt formations and it is the same for the mountains of 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. Reindeers reside in the east Highlands.
Nestled between the glaciers Eyjafjallajökull, Mýrdalsjökull, and Tindfjallajökull is Þórsmörk (Thor's Valley), a nature reserve in the southern Icelandic highlands. Þórsmörk is one of Iceland's most popular hiking destinations.
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.
Landscapes and Geology
Contrasting vistas of lush oases and roaring glacier rivers cutting through black desert expanses not only make Þórsmörk unique to 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.
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.
Fimmvörðuháls is a 30km trail that takes you into the hills beneath the Eyjafjallajökull glacier volcano and to the volcanic craters Magni and Móði, which are still steaming from the eruption of 2010. The 55 km 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 - April 30th) the road into Þórsmörk is impassable. In summer (May 1st - October 15th) a special 4x4 mountain bus runs three times per day from the BSÍ bus terminal in central Reykjavík. Once there you have the choice 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.
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, its 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 famers 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, Þórvaldseyri, 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 is rumbling...
Gigjokull is one of two glacier outlets from the glacier volcano Eyjafjallajokull, the other being Steinholtsjokull.
The 2010 Eyjafjallajokull eruption was close to the head of Gigjokull. Gigjokull empties out of the summit crater area at 1600 meters (5249 feet), flows across the ice cap to 1500 meters (4921 feet) and then descends in an icefall down 200 meters (656 ft). Water flowing from Gigjokull enters the Markarfljot river and eruptions in the area have caused great glacier bursts, 2010 being the latest example.
Hvolsvöllur is a small town of 950 people in south Iceland, conveniently located by the ring road. The local airport has flights to the Westman Islands.
Economy and transport
Hvolsvöllur’s main economy is services to the surrounding agricultural area, which has an additional 600 people, meat processing and tourism.
Museum
The area features prominently in one of the most famous Icelandic sagas, Njál’s saga. There is indeed an excellent Icelandic Saga Centre in the town that we recommend checking out. It has two exhibitions, ‘The exhibition of Njála, introducing guests to the characters of the sagas along with the Viking cosmology and the literary art and one on the history of trade, commerce and the cooperative movement in the 20th century. You can also view a model of Alþingi, Iceland’s parliament, founded at Þingvellir in 930. There is also a nice gallery there and a good restaurant in the Saga Hall, a replica of a medieval longhouse.
Nearby attractions
Hvolsvöllur has a number of interesting hiking routes in its vicinity. Among interesting sights is the large and peculiar rock Drangurinn by the farm Drangshlíð, under the Eyjafjöll mountains. Hvolsvöllur is also a short drive from many other interesting attractions, among them some of Iceland’s top ones. One of Iceland’s oldest swimming pools, Seljavallalaug, is about 44 km from the town. At a 14 km distance is the rural area of Fljótshlíð and the farm Hlíðarendi. According to Njal's Saga, its hero, Gunnar, lived there.
There is good trout and salmon fishing in the nearby rivers. Several interesting caves, both natural and man-made are in driving distance from Hvolsvöllur, 18-40 km. There is also a number of beautiful waterfalls not far off, the most well known being Seljalandsfoss, which you can walk behind, and Skógafoss, one of Iceland’s highest and most beautiful falls. Forests and groves can be found no further than 9-18 km from Hvolsvöllur.
