Hraunfossar ('Lava Falls' in English) in Borgarfjörður district is a series of beautiful waterfalls formed by rivulets streaming out of the Hallmundarhraun lava field. It is located in West Iceland near another waterfall called Barnafoss.
Geography and Surroundings of Hraunfossar
The lava field that Hraunfossar trickles through flowed from an eruption of one of the volcanoes lying under the nearby glacier of Langjökull, the second largest ice-cap in Iceland. The waterfalls pour into the Hvítá river from ledges of less porous rock in the lava.
The Hvítá river is one of the most popular rivers amongst visitors for two reasons. Firstly, it is the most easily accessible rafting river from Reykjavík, with rapids that are manageable even for total novices. Secondly, it is the river that hosts the mighty waterfall Gullfoss, one of the three sites of the popular the Golden Circle route.
Because the area around Hraunfossar used to be the site of constant eruptions, the lava fields are known for their hidden caves. The country's longest cave, Víðgelmir, can be found near the waterfall. This amazing feature is 1,595 metres long (5,200 feet), up to 15.8 metres high (52 feet) and 16.5 metres wide (54 feet).
Its geological history may be fascinating, being just a thousand years old, though its human history stirs just as much intrigue as the lava field was once home to bandits and, according to folklore it is the home of trolls.
Another major site near Hraunfossar is an incredibly short walk away, and though also a waterfall, could not be more different. Barnafoss surges down a narrow, rocky valley with ferocious power, foaming and churning quite spectacularly. According to legend, however, the force of these rapids led to tragedy.
It was said that an old stone bridge once went over the falls, and two boys at a nearby farm, bored at home, attempted to cross it to catch up with their parents at church. However, they felt dizzy due to its height, fell, and drowned.
The legend ends in two different ways, with the least interesting saying the mother in grief simply ordered the bridge destroyed. Other tales say that she cursed the bridge using an Icelandic rune so that any who crossed would meet the same fate as her sons.
In this version, the bridge and curse were later broken by an earthquake.
The story led the waterfall its name; it translates to ‘Children’s Falls’.
Settlements near Hraunfossar
The nearest settlement of significance to Hraunfossar is Reykholt.
This tiny village has a huge history, being home to the legendary writer, chieftain, lawspeaker and poet Snorri Sturluson. Without Snorri, huge amounts of Icelandic, Nordic and even British history would be unknown.
He alone at the time catalogued a history of Norwegian kings and their relations with other monarchs through the work Heimskringla, as well as the Norse mythological beliefs through Prose Edda. It is also believed that Snorri first wrote many of the sagas still read today.
Reykholt has a centre dedicated to Snorri called Snorrastofa, which discusses his fascinating life as much as his works. Working during the times of Iceland’s tumultuous civil war as a chieftain, lawspeaker and spokesman of the Norwegian king, who had ambitions to take the country, it is a story with as much politics, betrayal, blood and sexual impropriety as Game of Thrones.
Hraunfossar is also reasonably close to Borganes, another town with a long history. Here, visitors can see the Settlement Centre with its two exhibitions on Iceland’s past, one is on the first people to reach this island over a thousand years ago, and the other is on Iceland’s most famous saga, Egil’s Saga.
Húsafell is a large farm and church site in the Borgarfjörður district of West Iceland. With incredible natural beauty, it has been a popular resting spot for travellers since the earliest days of the country.
History of Húsafell
Húsafell is quite inland for an Icelandic settlement, made possible due to the fertile lands and relative lack of eruptions in the area. In spite of its distance from the coast, fishing has always been popular due to the trout lakes and salmon rivers within it.
A rectory once stood on the farm, gaining it fame as a location across the country when it was in its deepest religious throes, although all that remains now is a church.
The settlement was also well known for being somewhat of an oasis for weary travellers. Those travelling from regions such as the north, the Westfjords, and the Snæfellsnes Peninsula, on their way to and from Reykjavík or Þingvellir National Park, would often find that this was one of the very few places en route they could comfortably find refuge and food.
Due to Iceland’s harsh conditions, it became very taboo to turn down a houseguest, although to counter this, due to its scarcity of resources it was also taboo to stay longer than three days.
Húsafell gained a new reputation in the 19th Century when a colony of artists, including Jóhannes S. Kjarval, perhaps the country’s most important painter, lived and worked there. It has continued this tradition for art, with sculptor and musician Páll Guðmundsson being its most famous current resident.
Guðmundsson is best known for his carvings of stone faces, and for the stone harps he has created. He has played these alongside the internationally acclaimed Icelandic band, Sigur Ros.
Services and Features of Húsafell
Today, Húsafell is most popular and well-known as a camping location. There are many campsites, cabins, bungalows and holiday homes to be rented in the area, making it very popular amongst both locals and travellers. The old farmhouse, dating back to 1904, is also now a hotel.
Hiking is very popular, due to the beautiful birch forest of Húsafellsskógur; due to the fact that Húsafell is reasonably sheltered, the trees here can reach four metres (13 feet) tall, which is unusual in Iceland. Because of the force of the wind, Icelandic birch tends to form more like a gnarled bush.
This forest grows from a lava field, where geothermal pools can be found.
The dramatic mountain Tengil also provides many hiking opportunities; it was this mountain that named the area, with ‘húsa’ meaning home and ‘fell’ meaning ‘mountain’.
Húsafell is also blessed with its proximity to many incredible natural features of Iceland. Two of the most significant of these are the waterfalls Hraunfossar and Barnafoss, which are located right beside each other. Hraunfossar trickles in many tiny streams from a wide plateau of jagged lava rock, while Barnafoss rushes down a narrow valley with daunting force.
The highest flowing hot spring in Europe, Deildartunghver, is also found nearby.
For those seeking to explore the Snæfellsnes Peninsula or Westfjords, Húsafell provides a great location to spend the night before, putting you closer to both locations.
The mighty Langjökull, the ‘Long Glacier’, is the second-largest glacier in Iceland, at 935 square kilometres (361 square miles). For jeep and snowmobile trips, Langjökull is the most popular glacier in Iceland, and skiing and hiking here is possible as well.
Highland tracks
Langjökull is located in the Highlands, and two main highland tracks, connecting the north and the south of Iceland, lie alongside it.
The Kaldidalur road stretches from Þingvellir National Park northwards to Húsafell. The Kjalvegur road, meanwhile lies east of Langjökull and west of Hofsjökull glacier, starting near the famous Gullfoss waterfall to the south, and passing through the beautiful Hveravellir geothermal area to the north.
The landscape of Langjokull
Langjökull is about 50 kilometres (31 miles) long and up to 20 kilometres (12 miles) wide, and the ice is around 580 metres (1,903 feet) deep at its thickest. The glacier reaches its highest point in its northernmost part, which is called Baldjökull, rising around 1,450 metres (4,757 feet) above sea level.
The glacier lies over a massif of hyaloclastite mountains. The tops of these mountains can be seen in certain places on the glacier. It also conceals at least two active volcanic systems, the calderas of which are visible from the air.
The best known of these systems fuels the geothermal area of Hveravellir, east of Baldjökull. Also in the east lies the Kjalhraun lava field, which formed about 7800 years ago.
To the northwest of the glacier is another system that produced the vast Hallmundarhraun lava field, through which the Hvítá river runs in the direction of Gullfoss waterfall. Also in the area is Iceland‘s longest lava cave, the fascinating Surtshellir.
Southwest of Langjökull is the Presthnúkur lava field, fissures of which creep under the ice. South of the glacier is the Lambahraun lava field and even further south lies the Skjaldbreiðarhraun lava field and the Skjaldbreiður shield volcano.
Compared to other regions in Iceland, the area is considered relatively calm, with only 32 eruptions in the last 10,000 years.
Into the glacier
Near the highest peaks of Langjökull exists a man-made ice tunnel, a true spectacle for any visitor passing by the glacier. Designed and constructed by geophysicist and presidential candidate Ari Trausti Guðmundsson, the tunnel exists to allow visitors to explore the inside of a glacier without having to come to Iceland in mid-winter for a chance to see the less-than-reliable ice caves.
Guests traverse beneath Langjökull's thick ice sheet, experiencing the vivid blue colouration within, and gaining an insight into the glacier's beauty, formation and processes. It is the only place in the world where this is possible. ‘Into the Glacier’ tours are often combined with adventure activities such as snowmobiling.
Nearby glaciers
The glaciers located nearest to Langjökull are Eiríksjökull, which conceals the highest mountain in west Iceland, and Þórisjökull. Hrútfellsjökull also lies on the east side of Langjökull.
Between Þórisjökull and Geitlandsjökull is a valley called Þórisdalur. Along with stunning views, it features prominently in Icelandic folk tales; the outlaw Grettir the Strong of Grettis Saga, for example, is reported to have resided here for one winter.
Langjokull and the Golden Circle
Iceland’s most popular sightseeing route, the Golden Circle, would not be possible if not for Langjökull glacier; none of its three iconic features would exist in their current state without the melting ice.
Gullfoss waterfall is the most obvious example of this. The river that feeds into it, the Hvítá, is a glacier river flowing straight from Langjökull; the scale of the ice cap is hinted at by the sheer volume of water that cascades here every second.
The hot springs at Geysir, meanwhile, are supplied with water underground. Meltwater from Langjökull feeds into the surrounding lava fields, which have very porous rock, and flows in a subterranean river to the geothermal area, where it comes bursting out of the naturally forms vents.
While Þingvellir would still have its National Park and World Heritage status without Langjökull, which it received for being the original site of what is now the longest-running representative parliament in the world, it would be notably less beautiful.
Many springs exist throughout the park, also formed by the underground meltwater of the glacier. Due to its long filtration process, the water emerges as some of the clearest naturally occurring water in the world.
Silfra fissure, therefore, is the best snorkelling and diving location in the country and consistently ranked as one of the top ten places for such activities in the world.
Global warming
Langjökull is shrinking fast and concerns have been raised about the glacier due to the effect of global warming. Some researchers fear that if climate change continues at its current rate the glacier may be gone in 150 years. Less optimistic scientists have said it could be gone in as few as 50.
