9Vatnajökull Ice Caves, Iceland

The caves form as glacial rivers below the Vatnajökull glacier retreat and freeze during the winter. Standing inside the ice caves, one can hear the glacier sing a chorus of cracking sounds.

But don’t fret, these sounds are not because it is going to collapse, but rather because the cave is moving along with the glacier. What’s more is that each year the caves form in completely different places, making each cave as unique as the snowflakes that they are formed from.
