Tunnshello, also named Tunnshellefossen or Tunneshelle, is an unnofficial name of a huge waterfall near train station Berkevam along the famous Flåmbanen. Berekvam is part of the municipality Aurland in the region Sogn og Fjordane. It is also possible to drive to the Tunnshello: from Flåm take the Flåmdalsvegen to the south, following the train track for 10 kilometers. The road is closed for cars after station Berkevam.
Tunnshello is a waterfall in the river Tunnshelloelvi with a total height of 445 meters, maybe even more. The waterfall and river is named after the farm in front of the waterfall. Best visit the waterfall early summer or in the summer when warm weather melts snow from the mountain plateau above Tunnshelo.
The Flåmbanen is a popular tourist attraction where a train brings you from Flåm to Myrdal. The height difference is 865 meters which has to be done in 20 kilometers, the second steepest railway in the world. On the way you can enjoy several waterfalls, named and unnamed. Be sure to make a reservation in the high season. It can be very crowded.
The first waterfall you pass is the Brekkefossen, on the right. The next, a little bit further (also on the right) is the Rjoandefossen, the one with the nicest colors in the most beautiful landscape. Near station Berekvam you will see several waterfalls on the left, the biggest (unofficial named) one is Tunnshello. Then you will pass by the Kardalsfossen, but this is better visible when walking down from Myrdal.
The first short stop is the one at the Kjosfossen. From here you will see several streams and you will have a beautiful view on the Myrdalsfossen which plunges down over 225 meters. When walking down from Myrdal you will decent on a trail besides the waterfall. In Berekvam we took the train back to Flåm.
