through the heart of Wallis mountains with spectacular views.
By the way - I don“t want to be an insufferable "know it all" but it is called Pfulwe (not Pfulroe) I recommend to correct it to have the right query name.
I once tried Rimpfischhorn from Flue hut via Pfulwe and I had to turn round at a height of 4000 m because of bad weather (blizzard in august - very nice).
