Dimmuborgir Lava Field

Dimmuborgir, often referred to as the "Dark Castles," is an expansive lava field located near Lake Mývatn in northern Iceland. This extraordinary natural formation is a labyrinth of towering lava pillars, arches, and caves, created by a volcanic eruption around 2,300 years ago. The lava flowed over a marshy area, and as the molten rock cooled and hardened, it formed the eerie and dramatic shapes that can be seen today.

The landscape of Dimmuborgir is unique and otherworldly, often compared to a mythical or enchanted place. In Icelandic folklore, Dimmuborgir is said to be the home of trolls and other mythical beings, adding to its mysterious allure. The area is also rich in flora, with mosses, small shrubs, and flowers that add a touch of color to the dark, rocky landscape where visitors can explore various walking paths that wind through the lava formations, each offering different perspectives and stunning views of this natural wonder.

Dimmuborgir Lava Field Facts

Dimmuborgir is a geologically significant site with unique volcanic formations. Below are some key facts about the lava field:

• Area size: Approximately 1-2 square kilometers

• Formation: Created over 2,300 years ago by a massive volcanic eruption

• Lava thickness: The lava flow is estimated to be around 10 meters thick

• History: Formed by a lava lake trapped in a lava tube; the top solidified while the bottom drained out, leaving behind these distinctive lava formations

• Time to visit: Visitors typically spend 2-3 hours exploring the trails and formations

Geology and Formation

Dimmuborgir emerged from the volcanic eruption of the Þrengslaborgir and Lúdentarborgir crater row, with its lava flowing to the lowland area of Mývatn. As the front of the lava flow advanced, a lava lake was created that partially subsided, coagulating into hollow pillars and formations, each unique in kind. These pillars formed when steam from trapped water created openings in the molten lava and where the solidified crust above collapsed in some areas, forming caves and arches. Also interesting in structure, the lava field resembles a collapsed magma chamber, which is seldom seen anywhere on Earth.

Dimmuborgir consists of big formations of lava rock; some of them reach as high as 20 meters. Its formations give the area a resemblance to ancient ruins, by which it got its name, meaning "dark castles" or "dark fortresses." It is a wonder of geology and testimony to the powerful volcanic forces that have shaped Iceland.
