Dimmuborgir
Dimmuborgir is a striking lava field of caves, arches, and pillar-like rock formations near Lake Mývatn, formed when a lava lake drained away and left hollow structures around collapsed vapor chambers. Its jagged, fortress-like formations make it one of the most visited and photographed sites in the Mývatn area.

Plan the stop
- Who it suits
- 5+
- Uneven lava-rock paths, low cave openings, and trip hazards suit children old enough to walk confidently on rough terrain rather than toddlers.
- Allow
- 1 hr 30 min
Accessibility
- Wheelchair · Limited
- The short Kirkjuhringur loop near the entrance has designated accessible parking and is relatively flat, but most of the trail network crosses uneven volcanic rock with narrow passages between formations, unsuitable for wheelchairs.
- Limited mobility · Limited
- Short entrance loops may work, but most paths include uneven lava, narrow passages, and trip hazards.
- Sensory · Partial
- The lava formations can feel enclosed and maze-like, with shadows, crowds, and uneven footing.
- Cognitive · Limited
- The trail network can be confusing because formations and path junctions look similar.
Why it matters
The field formed around 2,300 years ago when a lava flow from the Þrengslaborgir/Lúdentsborgir crater row spread over a wetland, causing marsh water to boil and steam to rise through the molten rock, building the hollow pillar formations left behind as the lava drained away. In Icelandic folklore the site is linked to the underworld, with tradition holding that Satan landed here after being cast out of heaven.
