Iceland is the perfect location for an ice cave adventure

Glaciers cover 11% of Iceland, and the climate is perfect for ice caves. In spring and summer, meltwater usually forms them as outflow tunnels. In the fall, when temperatures have gone below freezing again, they are ready for exploration until next spring. The ice cave season varies due to temperatures and weather conditions but typically extends from November until May. 

Why is glacier ice blue?

Ice crystals reflect blue light when air has been pressed out of snowlayers

Glacier ice often displays a distinctive, soft blue hue that reflects off the walls of ice caves and icebergs. This unique color is due to its composition: glacier ice is made from highly compacted layers of snow-formed ice crystals, unlike lake ice, which lacks a crystalline structure. As more layers build up and compress the air out of the packed snow, the ice becomes transparent, reflecting blue light.
