Name

"The Seven Sisters" ( or ) is located on the northern side of Geirangerfjorden, and directly across the fjord lies a single waterfall called "The Suitor" (Norwegian: Friaren). The legend of the seven sisters is that they dance playfully down the mountain. Meanwhile, across the fjord, the suitor (or courter) flirts playfully with them from afar.
