I took this picture in July of 2009. I was lucky to get to this place during low tide. On the high tide chest-deep water washes against vertical cliff wall right behind those rocks. This spot on Reynisfjara beach is not always reachable even during low tides. Due to powerful storms, coast line is changing, and on some years this tiny stripe of sand remains underwater even on low tides. When you go there - make sure you escape before hight tide comes. Good luck!
