Highlights: South Iceland is the most popular part of the country and contains some of the most beautiful natural attractions in Iceland, among them the Golden Circle, some of Iceland's most famous active volcanoes as well as the beautiful Jokulsarlon glacier lagoon.
Geography
South Iceland is usually divided into the fertile South Icelandic lowlands between Hellisheidi and Eyjafjallajokull volcano on the one hand - and on the other hand the eastern part with the big volcanic glaciers Eyjafjallajokull and Myrdalsjokull (home of Katla) and flattened sands stretching towards the sea.
The South Icelandic lowlands
The South Icelandic Lowlands stretch nearly 100 km from Hellisheidi in the west towards Eyjafjallajokull in the east as a very flat and fertile farming land. From the shore the lowland stretches about km towards the inland. This is the best agriculture area in Iceland. The whole area is geologically very young, mainly of tuff type, formed during the Ice Age by the lava flows of the numerous volcanoes of the area. The area is indeed surrounded by volcanically active mountains on all sides. The glacier rivers of the area have helped filling the lavas with sand and clay, leaving it more and less smooth and fertile. Very strong earthquakes are found in this area as well.
The most active volcanoes of the area are Hekla and Eyjafjallajokull. No less active and not far off, but on the east side, is Katla, which we’ll adress in the eastern part-section. South of the mainland are the volcanic Westman Islands, famous for the 1973 eruption as well as the eruption in 1963, when Surtsey island was formed. Closely linked to the volcanic activity in the south is the geothermal heat found in many places, the best known being the Geysir area, which forms a part of the famed Golden Circle, which also consists of Gullfoss waterfall , Iceland's most famous waterfall as well as one of its most beautiful, located in the popular rafting river Hvita and Thingvellir National Park, comprising three of Iceland's most beloved natural attractions.
The earthquakes of the area bear witness to the fact that Iceland is still in shape. This is further evidenced by the endless number of fissures in the lavas, fractures in the mountains and certain pieces of lands sinking. The area of Thingvellir is the best known example of this, showcasing the continental drift. Thingvellir is a UNESCO World Heritage Site and the location of the old parliament, Althingi, (now situated in Reykjavik) and one of Iceland's most important sites.
Another of Iceland's most popular attractions is the beautiful Thorsmork valley, situated between Myrdalsjokull and Eyjafjallajokull.
Natural harbour-sites are hardly any on the South shore, due to sand produced by the glacier rivers. A few towns are found in the area, Selfoss being the biggest one, Hveragerdi is another, then there are Hella and Hvolsvollur, all conveniently located by the ring road. By the shore are three fishing villages; Thorlakshofn, Eyrarbakki and Stokkseyri. Thorlakshofn the only one of those that can accommodate modern ships and ferrys. The ferry to the Westman Islands sails from there. A new harbour has been built on the sandy coast opposite the Westman Islands. The whole south shoreline offers some of the most gigantic braker waves that you are likely to see.
Culturewise, in addition to Thingvellir, we reccomend the ancient bishop seat of Skalholt (weekends at Skalholt further offer rich music life). Also, Iceland's most famous saga, Njal's saga takes place in the South lowlands. We further recommend the large reconstructed turfhouse near Stong and the ancient excavated ruins.
For sports, horse riding is popular in the area as well as catching salmon or trout, hiking, and river rafting in Hvita.
The east part of South Iceland.
This is the area south and east of Myrdalsjokull. The volcanic glaciers Eyjafjallajokull (near the border of the eastern and western part) and Myrdalsjokull, dominate the view. The landscape has been shaped by volcanic eruptions and vast sands stretch to the sea. Some agriculture is found here, however, with the farms in a row alongside the mountains. A few large glacial rivers fall down in this area which also has striking waterfalls, such as Skogafoss and Seljalandsfoss.
Eyjafjallajokull is already well known for its 2010 eruption, disturbing air communication all over Europe for many days. Much more serious,however, would be an eruption from Katla, a volcano in the eastern part og Myrdalsjokull.
Katla’s last eruption was in the year 1918, when an enormous flood of water exploded from the glacier in a matter of minutes, threatening the local farmers of the area. Large amounts of ash and muddy material were brought to sea to form a new land of sand, Kotlutangi, later washed away by the sea. No people were killed in this eruption. Eruptions in Katla throughout the ages have further created the vast sand area Myrdalssandur. Sixteen eruptions have been recorded for Katla since 930 at intervals of 13-95 years and the volcano is being closely monitored, as time may draw near to its next eruption.
In the same volcanic system as Katla (geologically speaking), are the Lakagigar craters, northeast of Myrdalsjokull. Those erupted in the years 1783-84; producing the largest amount of lava known in historic times. The ashes hindered the sunlight from reaching down to the surface of Earth, resulting in cold climate over northern Europe.
In this area – what we call the eastern part of South Iceland -, there are many places worth visiting: Solheimajokull is a beautiful glacier in a walking distance (an outlet of Myrdalsjokull); Skogar has a very interesting museum of older time traditions and Skogafoss is only a few km away from there. One of Iceland’s most famous hiking routes, Fimmvorduhals, starts from Skogar. Southwest of the village Vik is one of Iceland’s most spectacular beaches, Reynisfjara. Together with the promontory Dyrholaey, which is the southernmost tip of the mainland of Iceland, it offers a breathtaking view with amazing rock formations, a black pebble beach, an abundance of birds and the powerful waves of the North Atlantic Ocean crashing on the beach.
Further east stretches the world's most vast sand plain, Skeidararsandur. North of the sand is the fascinating Skaftafell preservation area. At its east end, south of Hvannadalshnukur, Iceland's highest peak, is Ingolfshofdi cape, with its rich birdlife, old fishermen's shacks and its lighthouse. Following the shore further east is the incredibly beautiful and ice-filled Jokulsarlon glacier lagoon. Not far off is the region of Sudursveit, featuring the culture center and heritage museum Thorbergssetur, erected in the memory of Icelandic author Thorbergur Thordarson.

Vatnajökull glacier is the largest ice cap in Iceland and the third largest glacier in Europe, covering 8% of the island's landmass. Vatnajökull National park can be found in the south west of Iceland and is a popular spot for activities like glacier hiking from Skaftafell, boat tours and ice caving tours from Jökulsárlón glacier lagoon, both of which are part of Vatnajökull national park.
Facts about Vatnajökull
- Surface: 8,100 km2
- Average thickness: 400 - 600 m
- Maximum thickness: 1,000 m
- Height: 1,400 - 1,800 m
- Highest peak: 2,200 m (Hvannadalshnjúkur)
Information about Vatnajökull
Vatnajökull Glacier belongs to the greater Vatnajökull National Park, which encompasses the former national parks Skaftafell, in the southwest, and Jökulsárgljúfur, in the north. Vatnajökull's highest summit is Hvannadalshnjúkur which rests on top of a stratovolcano known as Öræfajökull.
Underneath the glacier rests some of the most active volcanoes in the country, the most notable being Grímsvötn, Öræfajökull and Bárðabunga. Volcanic activity in the region has occurred on and off throughout the centuries, and many geologists believe that such a period is overdue for immediate future. If their calculations are correct, it would mean significant volcanic activity for Vatnajökull over the scope of the next half century.
The glacier boasts of over 30 outlet glaciers, which are channels of ice that flow out of ice caps but remain constrained on the sides of the valley. The major outlet glaciers of Vatnajökull include Dyngjujökull in the north, Breiðamerkurjökull and Skeiðarárjökull to the south. To the west, one can find the outlet glaciers Síðujökull, Skaftárjökull and Tungnaárjökull.
Glaciers are in constant motion underneath their weight; as they form over the centuries, the accession of snow exceeds its melting, creating a constant "push" on the ice cap. Each year, due to the melting ice water, new ice caves form that disappear come spring.
Numerous rivers run out of Vatnajökull, making up some of the greatest glacial rivers in Iceland:
- Tungnaá (west)
- Köldukvísl (west)
- Þjórsá (west)
- Jökulsá á Fjöllum (north)
- Skjálfandafljót (north)
- Jökulsá á Brú (north east)
- Jökulsá í Fljótsdal (north east)
- Jökulsá í Lóni (south)
- Hornafjarðarfljót (south)
- Jökulsá á Breiðamerkursandi (south)
- Skeiðará (south)
- Núpsvötn (south)
- Hverfisfljót (south)
- Skaftá (south)
Vatnajökull National Park
Vatnajökull National Park, in its current state, was established in June 2008. The park now covers an area of 14.141 km2, making it the second largest national park in Europe. Vatnajökull National Park has 14% coverage over the whole island of Iceland.
Rivers divide the highland plateau to the north of the park; an area that sees massive glacial flows in the summertime. The volcanic table mountain Herðubreið towers over this particular region, along with volcanoes Askja, Snæfell and Kverkfjöll.
The canyon Jökulsárgljúfur was carved out by glacial floods centuries ago. At the upper end of the canyon, you'll find Dettifoss, the most powerful waterfall in Europe. Further north, the horseshoe-shaped canyon Ásbyrgi is believed to have formed when Óðinn's horse, Sleipnir, stepped his foot down from the heavens.
East around Snæfell, one can find wetlands and ranges, home to roaming herds of wild reindeer and abundant birdlife. Steep mountain ridges make up the south side of Vatnajökull, where outlet glaciers crawl in between the ridges onto the lowlands. The sandy plains of Skeiðarársandur also lie to the south as they reach out to sea. The glacial river Skeiðará runs through this vast desert.
One of Iceland's most visited landmarks is the Jökulsárlón glacier lagoon, which sits at the head of outlet glacier Breiðamerkurjökull. There, large icebergs that have broken off the glacier gather to float in the lake before ending up in the Atlantic Ocean, or on the nearby Diamond Beach.
The Future of Vatnajökull
The volume of Vatnajökull reached its peak around 1930 but has since been in a steady process of decline. Because of rising levels of global temperature, approximately over the last 15 years, Vatnajökull has on average lost about a metre of its thickness annually.
If temperature levels continue to rise, the glacier could be all but gone nearing the end of the next century, leaving only small ice caps on top of the highest mountain summits.

Skaftafell Nature Preserve can be found in Öræfasveit, the western region of Austur-Skaftafellssýsla in Iceland. Skaftafell once used to be a national park in its own right but was merged with the far larger Vatnajökull National Park in 2008.
Skaftafell is notable for its rich flora, growing between sands and glaciers, and for its amazing and contrasting scenery. At Skaftafell, visitors will find a wealth of natural attractions, from cascading waterfalls to panoramic views over this picturesque region.
Like many areas along the South Coast of Iceland, Skaftafell Nature Preserve is known for its glorious hiking trails. You can take short and easy treks to the waterfalls Svartifoss and Hundafoss, as well as to the gorgeous Skaftafell glacier. A little further along, guests will stumble on the mountain, Kristinartindar, as well as the scenic Morsardalur Valley.
Skaftafell is also the perfect base camp for those seeking to climb Iceland’s highest peak, Hvannadalshnúkur, or for those wishing to spend a number of days exploring the region's attractions, including Vatnajökull glacier, Jökulsárlón glacial lagoon and the nearby Diamond Beach. It is also an excellent region to try your hand at a spot of either ice climbing or glacier hiking; both activities are two of the most authentically Icelandic experiences you can partake in whilst in the country.
Skaftafell Visitor Center
Skaftafell also boasts a Visitors Centre, acting as the main information and meeting point for tour operators and independent travellers. At the Skaftafell Visitor Centre, you will find answers to virtually any questions you might have about the greater Skaftafell area, including its history and geology. The Visitors Centre also contains information about nearby hiking trails, recreational options and accommodation.

Svínafellsjökull in an outlet glacier of Vatnajökull, the largest ice cap in Europe, found within the Skaftafell Nature Reserve in Iceland's south-east.
It is one of the most popular glacier tongues to hike, with some tours upon it lasting throughout the year; ice climbing is also possible here. Because of its dramatic ridges, plunging crevasses, spectacular views and vivid blue and white colouration, it was used in Game of Thrones Season 7 to represent the harsh lands North of the Wall.
Skaftafell, part of the Vatnajökull National Park, is renowned for its glacier tongues, waterfalls, lava-landscapes and many hiking trails.

The South Coast of Iceland is the country's most visited sightseeing route, along with the Golden Circle.
The famed South Coast shoreline stretches from the greater Reykjavík area and is dotted with natural wonders such as cascading waterfalls, volcanoes both active and dormant, black sand beaches and glacier lagoons.
Geography, Nature & Wildlife
Iceland is divided into eight geographical regions. Out of these, the Southern Region is the largest, as it spans over 24.000 square kilometres with its administrative centre in the municipality of Selfoss.
What is known as the South Coast embodies the shoreline of this particular region. The area consists of a lowland that is mostly composed of marshlands, bays and cultivated pastures that are met by a series of black beaches where the estuaries to the east and west of the district close off the coastal body.
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 shore line.
The region boasts vibrant bird life during all seasons. It is not only rich with both marshland birds and seabirds but also migrating birds such as the North Atlantic puffin. Some species stay throughout the harsh Icelandic winter, including the northern diver, the loom and various species of gulls and ducks.
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 highlights in their correct order are:
These attractions count for but 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 close to Seljavellir by the Skógar Village there's Seljavallalaug, one of the oldest swimming pools in Iceland.
