Vatnajökull Region is a great place to visit one of Iceland’s natural wonders; the ice caves. The ice caves form during the winter months in the outlet glaciers of Vatnajökull, one of the biggest glaciers in Europe by volume. In the fall, professional local guides go scouting for the ice caves for the coming winter season.
How are they formed?
In some countries, you have almost the same ice caves year after year as the temperature there is constant. However, Icelandic caves are different. Each winter the weather cools and conditions change. Guides start looking for new caves, large and safe enough to explore on the inside.
Most of the ice caves are formed as canals for water that run through or at the bottom of the glacier. The water digs its way from underneath the glacier and forms the caves. Usually they are formed in the summer when the flow of melt water is at its peak. Then they are full of water and not accessible. When the shedding stops during fall, the flow of water in the cave greatly reduces and usually stops completely throughout the winter. The temperature becomes cold enough to strengthen the ice. As a result, what you have left is an ice cave.
During the winther there sometimes are wamer periods with strong wind and rain. Then the caves are flooded with water and become dangerous and impassable.
You always go with a guide!
The ice caves are only accessible during winter months, from November and usually throughout March, depending on the weather. The beautiful ice caves are very dangerous if you are not accompanied with a trained guide that knows the glacier from inside out, you should not go there by yourself. The caves should never be entered without a glacier guide and proper safety gear. Before going into the ice cave with a tour operator, you are provided with a safety helmet and crampons for walking on the ice.
