Traveling through Iceland we came upon The Cave. The sites driving to the cave are spectacular, Seeing the lava fields and surrounding mountains and volcanoes with snow on them are breathtaking..
Not being prepared as we usually are, and reading the previous reviews beforehand, we arrived, paid and jumped in line for the next tour. The steps entering the cave were icy, (and as others have noted), it is Iceland, so you must deal with it, but it is rather dangerous for being stairs. It was cold down there, so people need to come prepared. Children- it is good for the children to see and hear this education, however, the parents need to realize what they are getting into with the distance in the cave, the time spent down there and steps to climb, The guide did speak on geology and other topics to be rounded to a group with different likes and interests.
I do not think I would have went to the cave in the first place if I had done my homework and realized how expensive it was. But once we got that far out, we thought we would see what was down there. It was nice to be able to walk into the cave, but not for the price you pay. By marketing and the other tourists "not knowing", they will do well with tours that bringing in massive groups.
I would not recommend only based on the price.
