In reply to Helenhj:
We only did the first section to the Europahutte last year as the bridge after the hut hadnt opened(last week in June). Its a fairly exposed path most of the way with a few dodgy gullys to cross where there is a risk of stonefall with a rickety bridge across the largest one. Not a climb but you have to be aware of the dangers.
We found the ascent to the Col de Riedmatten very loose and people coming down it knocking rocks down quite scary. The ladders to the left on the Pas de Chevres look quite vertical but probably safer if anyone is descending the Col. The only other difficult section was the descent from the Col de Parfleuri where there was a snow slope and crampons were needed (I carry Katoolas -stretch over your boots in seconds and just handy) although the snow might have gone by July.
