Very nice steep transition from F to E. The path is laid out in tight bends and hardly exposed (just steep). Coming from France, the gap looks insurmountable. In mid-June there may be some old snow fields that can be hard in the morning. Caution is advised; very light crampons, such as those available for trail running shoes, may be helpful.
