These 15 Unbelievable Photos of Iceland’s Ice Caves Will Leave You Breathless – October 12, 2017

If you’re planning a trip to Iceland, don’t miss out on visiting the incredible ice caves. The mesmerizing caverns were formed within a glacier and most are formed by water running through tunnels in the ice or on the ground beneath the glacier.

According to Iceland Photo Tours, the water likely originates on the glacier’s surface through melting. The heat transfer than creates an air-filled cavity. Over time, movement of the warm air enlarges the cave through melting in the summer and sublimation in the winter.

It is also likely the ice caves formed as a result of geothermal vents or hot springs underneath the ice. Because the glaciers are constantly moving, the ice caves are not permanent. Additionally, the solidness of certain caves varies, making some less safe than others. For this reason, it is recommended to explore an ice cave on a guided tour.
