Kungsleden day 4 - Alternative route from Vistas to Tarfala

This hike from Vistas to Tarfala is to be considered extremely difficult and only for crazy People. There is no marked path over the last half of the hike, so you have to find your own way. In reality you will do about 23 km with an elevation of 1300m. But the hard part is the terrain. There are big rocks over half the distance of the hike, where you can easily hurt yourself. Your speed will be very low here and the dessert of rocks seems endless. It feels like you're crossing Mordor. At the end there is a very dangerous descent to the cabin of Tarfala. You can kill yourself here and no one will notice. We did it in less than 12h, but I think we were lucky to have the gpx route.
