Best rides over the Grossglockner have been late in the season. No traffic and often crystal clear air and blue skies, had lunch once at the Eidelwiesspitze (2700 odd metres up) sitting outside last weekend in October. I hope you catch some good weather next time you go. I will post details of my plans for next summer soon.

PS You do know the locals think Dunkel beer is for pregnant ladies!
That's a new one on me! Must tell my Swiss friend - he'll laugh at that one.
That's maybe why I had so much trouble finding it!
They sell "Unertl" in Soelden - very nice.
Looking forward to seeing your new plans.
