Mongefossen, Towering waterfall in Rauma Municipality, Norway.
Mongefossen is a waterfall in Rauma Municipality that drops vertically for 773 meters in a single cascade, making it one of the highest in the world. The water flows with a width of about 23 meters, creating a dramatic sight against the mountain rock face.
The waterfall formed through natural rock erosion over long periods, but was significantly affected in 1977 by the Grytten hydroelectric project. The Mongeelva river was diverted for power generation, which reduced the water flow substantially.
Norwegians recognize Mongefossen as part of their natural heritage, representing the country's commitment to harnessing water resources for sustainable energy.
You can observe the waterfall from the Rauma Line railway station, which sits between the villages of Flatmark and Marstein. This provides good viewing access with convenient train service for reaching the location.
The water originates from five mountain lakes and two small glaciers, flowing primarily during heavy rainfall or when reservoir levels overflow. This seasonal behavior makes the waterfall an especially changeable natural feature.
