Location: Vatnajokull glacier, Iceland.
Deep in the heart of the south side of Vatnajokull glacier you can find natural caves of kilometres of length. It could be dangerous if you trek along these riddles when the rivers inside are high because of rain or in spring because of melting ice. We explored one of this caves, named “ Crystal Cave”. Suddenly, outside started snowing and, through a chimney, snow come into the cave. We enjoyed this awesome moment.
