The Dachstein Ice Caves are located near Obertraun, Austria on the banks of Lake Hallstatt. These underground caves were formed over centuries with the oldest layers of ice being over 1,000 years old. The caves attract over 200,000 tourists a year who come to see the incredible ice formations that have formed within the depths of the caves. The structures were created by thawing snow that drained into the cave only to be frozen again once inside.
Even during the summer, these ice formations remain frozen, making it a tourist attraction all year round with new formations beginning to form each spring as water drips into the cave and then freezes.
