Data files is the most powerful waterfall in Europe. Of course I found this part of Europe so that goes for Iceland as well! It is so powerful that you can feel it through the ground. The spray was just incredible. I took some photos from the time and then went down closer and and only about 5 minutes I was completely drenched. All the camera equipment came through nicely and the rainbow was just unbelievable. Look for the people at the edges for a sense of the scale. There are actually two different falls and I hiked solo to the second smaller falls.
