Rangaafossen (Rangåafossen) is one of the many waterfalls in the Romsdalen (Rauma) near Flatmark, 26 km south of Åndalsnes in the region More og Romsdal.
Rangaafossen should be the third tall waterfall at the left side of the road. Unfortunately Rangaafossen is a regulated waterfall and the amount of water in the river Rangåa is highly reduced or even zero. First time I visited the Romsdalen (Rauma) was years ago in May when the rain kept falling and still Rangaafossen was hard to see. Second time, July 2017, I couldn’t discover any waterfall where Rangaafossen should be.
Rangaafossen once was one of the highest waterfalls in Romsdalen fed by Rangåvatnet on an altitude of 1126 meter until in 1975 Grytten power plant diverted (almost) all the water from Rangåvatnet and so the river Rangåa dried out.. The river Rangåa once dropped down over more then 900 meters. This makes that Rangaafossen was of the highest waterfalls in the country or even in the world. Only thing is that Rangaafossen is regulated and isn’t an official named waterfall.
Fortunately there are many other big waterfalls in the Romsdalen (Rauma) when driving from Andalsnes to Dombas (road E136)
Olmaafossen (1th waterfall on the right, one of the highest waterfall in the world)
Mongefossen (2nd waterfall at the left side, but is regulated and probably not visible)
Rangaafossen (3th waterfall at the left side, but is regulated and probably not visible)
Brurasløret,(4th waterfall at the left side, nice to see together with Gravdefossen)
Gravdefossen (5th waterfall at the left side and the most impressive waterfall)
Døntefossen (6th waterfall at the right side, beautiful with river in foreground)
Skokagrovafossen (7th waterfall at the left side, nice if you are standing near the waterfall)
Vermafossen.(8th waterfall at the right side, much bigger then it looks like)
Kylingbruafossen (9th waterfall(s) at the right side, close to Kyling bridge, unnamed but beautiful)
Slettafossen (10th waterfall at the right side, extremely powerful waterfall in the river Rauma)
Then there are still dozens of low volume waterfall not considered as a waterfall.
Not far from Romsdalen (Rauma) you can also drive into the Eikesdalen with the enormous Mardalsfossen. A tourist attraction, but the waterfalls are very impressive to see and the walk to the base of Mardalsfossen is very pleasant. Anyway Eikesdalen is a valley with many big waterfalls and is a visit worthwhile. There is a nice campingsite in Eikesdal, a perfect base to explore the area.
