That’s crazy. I went on a tour on this same glacier just a month ago. Wondering if I was at the same ice cave because it was very accessible, had two entrances like described, the drive and hike times are about the same. So very unnerving!

When we were there, our guide even said to be very careful, to not talk loudly, and especially not to linger at the entrance. Because of his experience and also being trained in glacier search and rescue, we felt in good hands.

We were only a total of 3 people. You know nature can be unpredictable, but I can’t imagine 23 people in a fast melting ice cave was ever a good idea. Iceland is most likely going to have to change the law and ban ice cave tours in the summer.
