Lava Caves

Húsafell is a so-called ‘populated place’, and former priest’s seat in Borgarfjarðar county, which has fostered several personalities and artists. The farm, approximately 100 km2, was a pioneer for the transition from farming to tourism. And it seems to have been veeeery successful, as the farmer has had enough money to buy his own plane and to make his own airstrip (it is less than 2 hours to go by car to Reykjavík)…

In addition to Langjökull, there are several spectacular tours in the Húsafell area. One opportunity, which we took during the corona, was to visit a lava cave. The longest lava cave in Iceland is Surtshellir (Giant Surtur’s cave) almost 2 km long, while Víðgelmir is the largest (and widest, hence the name). It is still not short, 1.5 km is just fine.

Lava caves are formed when liquid basalt flows out of a volcano and forms a river of molten rock. The sides and top of the river will eventually cool down and solidify, while the river continues to flow in the crust, as inside a pipe. When the volcanic eruption stops, the lava flows out of the ‘pipe’, and what’s left is an empty cave. The volcano that formed Víðgelmir is located 33 km away, and was under Langjökull.

Víðgelmir was formed during a volcanic eruption around 930 AD, i.e. at the end of the Conquest Age. In 1993, bone remains and human belongings were found in the cave, dated 983-986 AD. At that time the cave was still warm, about 20 degrees. No wonder it was nice to live there in the Viking Age. House with central heating fixed and delivered by nature! A (pagan) poem has been written about this volcanic eruption, Hallmundarkviða. Most likely by someone who actually experienced it (!), and Þorvaldur Holbarki (who is mentioned in the Book of Conquest) is a candidate. It is said that he went up to Surtur’s cave and killed the giant that lived there. The trip inside Víðgelmir was both great and interesting. However, our cameras did not cope well with the darkness, so we have very few pictures. The cave was, however, more colorful than expected, and there are both stalagtites and stalagmites, although much has been removed by ravenous visitors. And then there was the fact that the walls looked like melted chocolate…

Unfortunately, there is no water in Víðgelmir, so there was no lava cave bathing. But after a cave trip, time is just right for a bath, and we would suggest a warm bath this time (since the cave is now actually cold). Húsafell Canyon Bad (Giljaböð) from 2019 is a spectacular alternative.

Giljaböð (The Gorge Bath).

You are transported to the canyon in a minibus, max 20 people (we were 4), and here the farmer Unnar Bergþórsson has really put in a lot of effort to make it all happen. To find hot water, drilling had to be done. And he drilled and drilled, and found heat 8 times, without water. You have to have water in the baths, and luckily he hit the rigth spot on the ninth attempt. Here he found a spring that delivers five liters of 47°C water per second. After 200 m of transport, the water flows into the hot pot at the perfect 39-41 degrees. In Giljaböð there is rough reuse and funny details. We fell for the pegs, made of used horseshoes.

Gentle reuse of horseshoes.

And then there were the closing mechanisms for the doors – a stone and a pulley. Cool!

A great bath! Correction, 3 very nice baths. One was down by the river side and had the river temperature (around 10 degrees).

Rather cool

The other was constructed to simulate Snorri Sturluson’s bath at Reykjholt. And it was just right and just a perfect temperature.

Bathing in style, like Snorri himself

If you want to build a bath like this, you need to know how to put one stone on top of the other. Luckily, they had a local stone stabling expert, as you can see from this underwater picture.

Puzzle without prefactured pieces

While lying in the bath, you can take a look at the pebbles around you. There are many different stones here. The baths are located in the middle of what was the magma chamber of the 2.5 million-year-old Húsafell Central Vulcano. Small conglomerates are from the magma chamber, but otherwise much of the old volcano has been dislodged into the sea by the ice ages that followed. And then a small river dug and created the beautiful Hringsgil (Ring Gorge), where the baths are located today. Welcome to Giljaböð !

Inside Langjökull

Iceland has more than 400 glaciers. Vatnajökull is the largest one, while Langjökull is number two. In Langjökull, a very special tourist attraction has been created: They have dug tunnels in the glacier, so you actually can walk inside it. Correction: They dig tunnels every night – with a mini excavator, otherwise the tunnels will be flattened in no time.

Mini Ice Excavator.

We took the glacial tour in 2020, during the corona, and the number of visitors were very low. The whole trip is spectacular: You are driven in special minibuses, with large tires that can be filled or deflated depending on whether driving on road or on ice. On the glacier, they release air from the tires so that the car can float on snow. Then a bumpy ride starts, on the ice, where next to the ‘road’ you can see crevasses here and there.

Once inside the glacier, you put on ice crampoons, and then time is just right for enjoying the moment in a completely foreign world.

Strange to be inside a glacier!

The glaciers are formed from snow that is deposited layer upon layer every winter. They are therefore a chronological journey through time, and studies of glacial ice can tell a lot about the conditions on earth a long time ago. We could see ‘annual rings’ in the ice, and a clear black stripe contained ash from Eyjafjallajökull’s eruption in 2010.

Eyafjallajökull’s eruption is clearly visible inside Langjökull.

The Italian news consequently referred to Eyaflallajökull as ‘Il vulcano con il nome impronunciabile‘ – The vulcano with the impronunciable name.

The ice tunnels covers a total of 800 meters, and there are several rooms that have been excavated. You can get married inside Langjökull! Our guide entered the ‘cathedral’ alone and sang for us. The acoustics were incredibly in the ice.

The Langjökull cathedral.

Water is a big problem in Langjökull, it flows everywhere. If it rains outside one day, this is noticed as an increased amount of water inside the glacier 3 days later. Here and there there are crevasses, in one spot they had built a bridge over. Another crack went down from the tunnel wall. They used it as a drainage – and this drain roared like a troll! Because of this, our 3-years old British companion cried of horror all the way out.

The Icelandic glaciers are in decline. If the trend continues, they will all be gone by the year 2200. This was easy to see near the glacier, where they have put up signs showing the glacier limit in previous years.

It is a while since the glacier reached here.

After a glacier expedition, time is just right for a bath, and preferrably a warm one. We went to the Krauma spa. This bath gets its heat from the hot spring Deildartunguhver. Here, 180 liters of boiling water flow per second! The spring heats the villages of Borgarnes and Akranes, which are up to 100 km away. Krauma opened in 2017.

Deildartunguhver.

Krauma is an absolutely beautiful facility, almost entirely black. Wonderful!

A bath or three at Krauma is just right. They also have a small ‘cold pot’, for those of us who like to alternate between hot and cold baths.

Nice view of the valley and the steam

If you need something to eat before driving on, you can buy food at the kiosk by Krauma. The meat soup is very good. But this is not lamb soup, here they probably cook it on the ewe itself. And the soup, it is to be consumed in the greenhouse!
