Frequently asked questions
What are lava caves in Iceland?
There are more than 100 volcanoes in Iceland. Lava caves, or lava tubes, are underground structures formed by molten lava flows due to volcanic eruptions. When the lava flow stops, the surrounding rock cools, leaving hollow tubes, creating unique lava caves across Iceland.
How do lava caves in Iceland form?
Icelandic lava caves form when a river of lava cools from the outside, forming a rock-crust surrounding still flowing lava. When this lava has flushed out, all that is left is the tube that cooled around it. Eventually, experts discover this tube in the field and once it is deemed safe, visitors are invited to explore.
