ミーヴァトンのおすすめランニングルート

Volcanic cave next to Lake Mývatn, famous for its blue hot springs nestled among lava rocks. Formed by geothermal eruptions and seeps, it offers a magical landscape for epic photos. Slippery rocks:

A beautiful place... and such clear water.

Grjótagjá is a small lava cave. It is famous for its beautiful geothermal hot spring located in the depths of the cave. Although it was once a popular seaside resort, geological activity between 1975 and 1984 raised the water temperature so much that it has not been possible to bathe in it since. The history of Grjótagjá begins in the early 18th century, when it was known as the home of the outlaw Jón Markússon. He used the cave for bathing. After the volcanic eruptions of the Krafla volcanic system in the 1970s and 1980s, the water in the caves became boiling and unusable for bathing. Temperatures have cooled slowly since 1984, but they can still warm unpredictably quickly. Grjótagjá has also received attention from Hollywood; it was even a filming location for HBO's Game of Thrones, where an iconic love scene was shot.

The lava caves are accessible from two locations. The entrances are narrow, and some climbing is required. Unfortunately, some are also very crowded! Since the recent volcanic activity, however, the water has warmed to almost 50°C, and swimming is now strictly prohibited!

Yes, it is worth staying here for a while.

In the grotto, be careful not to hit your head.

A long rift runs through the barren landscape east of Mývatn. A low rock hole on the side is the entrance to the underground. A few meters down over rough stones and you reach the underground lake of Grjótagjá Cave. Unfortunately, due to mass tourism and its repercussions, the place became heavily polluted again and again and then bathing was also forbidden. But also such a great moment to dive into the underworld for a moment.

Great and hot grotto, unfortunately no longer for swimming.
