Dimmuborgir
Dimmuborgir is one of the most distinctive places by Lake Mývatn: a dark lava-field maze of towers, caves, arches and walking paths below Hverfjall in North Iceland. It is easy to visit on its own, but it works best as part of a wider Mývatn route with geothermal areas, volcanic craters, Goðafoss, Dettifoss and the Diamond Circle.

What is Dimmuborgir?
Dimmuborgir is a dramatic lava field on the east side of Lake Mývatn. The name is often translated as Dark Castles or Black Forts, and it fits the landscape: visitors walk between jagged lava walls, natural arches, small caves and strange rock formations that feel almost built rather than formed.
The area is one of the easiest volcanic landscapes in North Iceland to explore on foot. Short marked trails give a quick introduction to the lava formations, while longer loops let you spend more time inside the maze. Dimmuborgir is also a strong photography stop because the lava shapes create frames, silhouettes and foregrounds in almost every direction.
How was Dimmuborgir formed?
Dimmuborgir formed about 2,300 years ago when lava from nearby eruptions spread across the Lake Mývatn area. As the lava moved over wet ground and shallow water, steam pushed up through the molten rock. When the surface cooled and the lava beneath drained away, parts of the crust collapsed and left the towers, caves, arches and dark lava walls that visitors walk among today.
The walking paths lead through lava pillars, rough walls and small natural openings in the Dimmuborgir lava field.
Walking through the lava field
Dimmuborgir is a good stop for travellers who want memorable scenery without committing to a difficult hike. The most accessible paths stay close to the main visitor area, while longer marked routes move deeper into the lava field. In summer the dark lava contrasts with green birch and moss; in winter the same formations can look even sharper against snow.
Small lava caves and openings are part of what makes Dimmuborgir feel different from the open volcanic landscapes around Mývatn.
Best things to do in Dimmuborgir
- Walk the marked paths: Choose a short loop for a quick stop or a longer route if you want more time among the formations.
- Photograph the lava arches: Dimmuborgir is especially strong for landscape photography because the formations create natural frames.
- Look for lava caves and openings: The small caves help explain why the area feels like a collapsed lava city.
- Connect it with Lake Mývatn: Dimmuborgir is best planned with the wider Mývatn volcanic area rather than treated as an isolated stop.
- Visit in different seasons: Summer brings green contrast, while winter gives the lava field a darker, more graphic look.
Photography and seasons
Dimmuborgir is one of the most photogenic stops in North Iceland because the lava shapes create endless foregrounds, frames and silhouettes.
