What kind of caves are there in Iceland?

Caves are important in Icelandic history. Most of them have served as shelters for people or animals in harsh winters. Some of them are still used as storage or curing sheds or barns for sheep.
Some caves in Iceland are lava tubes, long tunnels formed when flowing lava cooled and solidified. Melting ice took care of the rest and thence formed glacier caves. Others have formed due to the volcanic activity.

The following are some of Iceland’s most known and visited caves.

Glacier caves in Iceland

There are numerous glacier caves in Iceland. The difference between glacier caves and ice caves is that ice caves are bedrock caves that contain ice all year round, whereas glacier caves are formed within the ice of a glacier. Most of these caves are unstable and can collapse, which make it very dangerous for tourists. The best-known glacier caves in Iceland are formed because of geothermal heat, Kverkfjöll glacier caves in Vatnajökull being one example. Never go alone, always with an experienced guide!
