Rjukan, a town located 3 hours north-west of Oslo, Norway, is known as one of the darkest cities on earth
There are around 3,386 inhabitants in Rjukan, a town that got its name from the Rjukan Falls -a 104-meter waterfall that provides easy access to generating large quantities of electricity.
But first I walked to the summit of this mountain #7 which is one of the more popular mountain hike in Norway. Mt. Gaustadtoppen it is.
