description Lofthellir Cave Overview
Lofthellir is a lava cave in northern Iceland, located east of Lake Mývatn. It formed in a lava flow and remains cold enough throughout the year for ice formations to persist inside the cave, including other natural structures shaped by freezing conditions. Visitor access is organized through tours and requires suitable equipment, reflecting the cave’s uneven volcanic interior and cold conditions. The site is for visitors interested in Icelandic geology, lava tubes, and subterranean ice features.
help Lofthellir Cave FAQ
Where is Lofthellir Cave located?
Lofthellir is in northern Iceland near Lake Mývatn. Tours normally use the Mývatn area as their starting point and combine a rough vehicle journey with a hike.
Why does Lofthellir have ice formations throughout the year?
The lava tube stays close to freezing, receives little sunlight, and has airflow that helps preserve ice inside the cave. These conditions create natural ice sculptures even though Lofthellir is a lava cave rather than a glacier cave.
How old is Lofthellir Cave?
Travel and geological descriptions commonly date the cave to around 3,500 years old. Its passages formed when lava cooled and drained away from an earlier volcanic flow.
How is Lofthellir different from Víðgelmir or Vatnshellir?
Lofthellir is especially known for its year-round internal ice, while Víðgelmir in western Iceland is known for its large lava-tube passages and Vatnshellir is a guided cave on the Snæfellsnes peninsula. Lofthellir tours typically require helmets, headlamps, and traction equipment.
