During the winter months (usually from October to March), it is possible to visit ice caves, depending on the weather and safety conditions.
In some countries travellers can visit the same ice caves year after year, but the conditions in Iceland change meaning guides must look for new caves that meet safety requirements each season.
Ice caves should never be entered without a professional guide and proper safety gear.

In addition to natural ice caves, tourists can also visit man-made ice tunnels, which are accessible all year around.
