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.
Reykjadalur, the Valley of Steam, is a beautiful geothermal region close to the southern town Hveragerði. It is a popular place for hiking and hot spring bathing.
Hot Spring Bathing at Reykjadalur
Reykjadalur is best know for the heated river that runs through it. Water boiling out of dozens of hot springs in the hills trickle into one body, which is also fed with glacier and rainwater.
The result is a wonderfully warm, gentle stream. Depending on how hot you want the water to be, you can go up- or down-river for the perfect bathing temperature.
Hiking in Reykjadalur
The hiking route to Reykjadalur can be reached by driving through Hveragerði (which is about an hour’s drive from Reykjavík) along the Ring Road travelling South. A gravel road leads to a carpark, where the trail begins.
From there, you will cross a river, then start a gentle ascent. The path goes up, down and along the faces of hills; and though it sometimes gets quite steep, is manageable for anyone comfortable on their feet in reasonable health, so long as the weather is fair.
For forty minutes or so, you will hike passed many steaming vents and bubbling springs, while enjoying the beautiful views around Reykjadalur. You will then reach the warm river and can walk along it for twenty minutes or so to the perfect spot for bathing.
In summer, you will also see a wealth of flora blooming on the hills and in the valley, particularly lupins. Around the hot springs, the chemicals rising from the earth provide even more colour, dying the soil pinks, blues, greens, reds and yellows.
While it is viable to visit the hot springs alone, many tours also run to them so the area can be enjoyed with a group and a guide. These tours can be done on foot or horseback, and alone or alongside other excursions, such a sightseeing around the Golden Circle.
As with all hiking trails in Iceland, it is important to stick to the paths throughout. This is for your safety—considering the steep slopes, change of rockfalls, and boiling water—and for the protection of nature. Iceland’s flora is very delicate, and with the boom in tourism, strict rules are in place to protect it.
Services near Reykjadalur
Hveragerði has all modern services and amenities visitors may need. There is a supermarket, gas station, information centre, and several cafes and restaurants.
Interestingly, some of these restaurants utilise the geothermal forces in the preparation of their plates. By burying food into the boiling water under the earth, it cooks throughout.
Because of these forces, however, Hveragerði has gotten the nickname ‘the Earthquake Town’.
