Myvatn is a beautiful lake with many small islands in the north of Iceland, the fourth largest lake in the country. Along with its surrounding area, the lake is one of Iceland's most amazing natural attractions.
Some of the islands in Myvatn are pseudocraters, formed by steam explosions. The lake has rich birdlife and more species of ducks than anywhere else in the world. As for vegetation, it is one of the few places in the world that grows Marimo, also known as Cladophora ball, Lake ball, or Moss Balls in English, a species of filamentous green algae (Chlorophyta).
The Myvatn nature baths are also renowned throughout the world, a perfect place to relax, surrounded by breathtaking landscape.
Close to the lake is Dimmuborgir, a fascinating area of dramatic and chaotic lava. Norwegian symphonic metal band Dimmu Borgir takes its name from the the lava field, and it continues to inspire travellers from all over the world.
The Myvatn area is definitely one of the most beautiful places in Iceland. Don´t miss it!

Skútustaðagígar is the name of a row of pseudo-craters in north Iceland.
Geology of Skútustaðagígar
The Skútustaðagígar Craters are found in the Lake Mývatn area, which is very volcanic, being near to the Krafla volcano system. The nature of the lake itself and the volcanism of the region both led to the creation of these unusual formations.
During an eruptions, lava ran across the area of Skútustaðagígar, which at the time was swampy wetlands. The heat caused steam eruptions, which resulted in their crater-like shape.
As they were not the sources of lava, or volcanoes in themselves, they are not considered true craters.
Location of Skútustaðagígar
The Skútustaðagígar craters are surrounded by the remaining wetlands of the Lake Mývatn area. This region is a hotbed for birdwatching, with many species of duck found in the waters throughout the year.
The Lake Mývatn area has many other attractions, such as the Dimmuborgir lava fortress, the Grjótagjá hot spring cave, and the luxurious Mývatn Nature Baths.

Grjótagjá is a small lava cave located near lake Mývatn in north Iceland, famous for featuring a beautiful geothermal hot spring in its depths.
History of Grjótagjá
Grjótagjá’s known history begins in the early 18th Century, where it was known to be the home of outlaw Jón Markússon. Throughout Iceland’s history, their icy, jagged rocks, total darkness and reputation for trolls meant law-abiding folk avoided Iceland’s lava caves, making them the perfect spots for bandits who had been ostracised from Icelandic society by the parliament.
Little is known about Jón, but after his death, fears of his cave gave way to excitement at its potential. It was used by locals as a hot spring in the decades that followed until the 1970s, when Iceland’s unpredictable geothermal forces prevented them from doing so.
From 1975 to 1984, the Krafla volcanic system erupted nine times, resulting in (to say nothing of new expanses of lava, the creation of new caves and magma chambers and the release of toxic gases) the water’s caves to boil and make it unusable.
After 1984, the temperature has slowly cooled, but has been known to rapidly heat again; in the surrounding area, liquid rock is just two kilometres (just over a mile) under the surface of the earth, meaning it can be very unpredictable.
As such, bathing is no longer allowed in Grjótagjá. You are welcome, however, to at least feel the water and dip your feet in to relax.
The lava cave and hot spring, however, have such an ethereal, otherworldly beauty that they attract many visitors a year. This unique, fantastical appeal, did not go unnoticed by producers; HBO’s Game of Thrones even shot one of the season’s most iconic scenes here.

In Season Three, Episode Four, Grjótagjá is used as the setting for the much anticipated love scene between Jon Snow and the wildling woman Ygritte, where Jon Snow ‘proves’ his abandonment of the Night’s Watch by consummating their relationship.
In the televised version of the cave, there is a waterfall added with CGI, but otherwise, Grjótagjá is as it appears in reality.
Grjótagjá is far from the only place in Iceland used to build up the world of Westeros; in fact, it is not even the only one in the local area. Also in the Lake Mývatn area is the lava fortress of Dimmuborgir; in midwinter, this dramatic area was used to reflect the wildling camp of Mance Raider throughout Seasons Two and Three.
Also in the series are Mount Kirkjufell and the Reynisdrangar sea stacks in the penultimate episode of Season Seven, Vatnajökull glacier, on which ‘the Wall’ is built with CGI effects, and much of the landscape around Þingvellir National Park throughout. Icelandic mountain ranges can also be seen cut behind scenes filmed in countries such as Ireland and Croatia.
Getting to Grjótagjá
Grjótagjá is located conveniently in the Mývatn area, which is part of the most popular sightseeing route of north Iceland, the Diamond Circle, and on the Ring Road that encircles the country.
Reaching it and getting to the hot spring, however, requires a reasonable level of fitness and a little sense of adventure. There is a slightly rocky path that takes you from Dimmuborgir to the cave itself, which you will need to be careful descending into; lava caves are very jagged, and the ground is uneven.
There are car parking spaces beside Grjótagjá if you do not want to take the short hike.
The Namafjall geothermal field is located in Northeast Iceland, on the east side of Lake Myvatn.
At this area, also known as Hverir, you may see many solfataras and boiling mud pots, surrounded by sulfur crystals of many different colours. The area is quite smelly but something one gets used to after a while. The soil in the area has little growth and is sour due to erosion and the sulfur from the atmosphere. Indeed, the old rock-covered boreholes in the area give off a lot of hot steam, so we advise caution.
Around the area is a small hiking trail up to Namaskard pass and Namafjall mountain, returning to the highway and the parking lot.
Historically sulfur would be much sought after in the area. The same is true of the geothermal power. In 1969 a power plant was built west of the mountain, at Bjarnarflag, by the Laxa Power Company. This company later merged with Landsvirkjun. The plant currently produces 3MW of geothermal energy.
Concerns have raised over current plans to expand the plant to 90 MW. In particular there have been worries as regards the effect of the plant on the ecosystem of Lake Myvatn. The head of the environmental NGO Landvernd has recently called for a new environmental impact assesment. The matter continues to be debated.
