We walked up the glacier and the last sector we climbed a ferrata . At this time of the year (the end of August) the snow melt was progressing and climbing the glacier wasn't easy at all.
The key areas were two:
The second major difficulty was the place between the glacier and the ferrata. There was a one meter or even more big crevice and the wall of the ferrata was a few meters high plumb and the only possibility to hold was a tied rope thick as a shoelace. We had to drop a rope for assurance.
Here we are at the start of the ferrata. On the bottom of the photo you can see the crowding on this difficult part, where on our way back we had to wait and therefore missed the lift.
