ID:16090094 / The origin of the river Rhone is located near Gletsch, just in between of the Grimselpass and the Furkapass. Here at an elevation of 2300m there is the possibility to enter into the blue world inside the glacier without needing any special equipment because the tunnel is manmade and prepared accordingly. Unfortunately, as with many glaciers in the alps, the ice is rapidly melting and during my visits over the last few years the tunnel path seems to have changed quite a bit.
