Kjosfossen is a waterfall located in Aurland Municipality in Vestland county, Norway.

(Some of the Flam tourist maps are orientated with South at the top.)

The waterfall is located about 1.5 kilometres (0.93 mi) northeast of Myrdal Station.

During the main tourist season in the summer an actress dressed as a legendary Huldra (a seductive forest creature in Scandinavian folklore) dances and sings in front of the waterfall as the trains enter the station for the amusement of the tourists.

The waterfall gets as much as 900,000 visitors yearly, and is considered to be among Norway's most visited natural tourist attractions.
