Your tour guide is a highly qualified mountain guide expert, and ice cave expert. It's in his hands to decide each time which cave is best to visit depending on weather conditions and other issues.
New caves are searched for and discovered each autumn, to be visited in the winter. They are normally found in various different locations on the south side of glacier Vatnajokull and its outlets.
Sometimes the caves are very special, sometimes not as special, but become very special in the right light and conditions. Some caves we find are very stable and we can go in there in any weather, but others are less safe and we might not even go there at all, even if they are very beautiful.
Some of the caves are only accessible in temperatures below zero, such as when there is water on the ground that needs to be frozen all over in order for us to walk into the cave.
Note: The actual view of an ice cave may look different from pictures since ice caves are a natural phenomenon and are constantly changing. How they look may vary depending on the season, time of the day, lighting, and other factors.
