vatnajokull

Vatnajokull, Europe's largest glacier and one of the most beautiful glaciers in the world, has been tinged with a black color due to Grimsvotn volcanic ash in Iceland.

Pipiwai in Hawaii or Azores in Portugal are the most beautiful mountain trails in the world, and are the favorite destinations for adventurers.

Photographer Mikael Buck has recorded wonderful photos in the cave in the heart of Vatnajokull glacier, Iceland.
