Dimmuborgir, means "dark cities" or "dark castles" in Icelandic. This formation of volcanic origin near Lake Mývatn contains, among other things, the bizarre lava cave "Kirkja" (church), which is shaped like a Gothic cathedral and also served as the namesake of an Icelandic black metal band.

Nice path towards the crater. You can walk all the way around once at the top. Also accessible in winter but use snowshoes for your own safety. Really come in handy when climbing and descending.

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.
