|Subject: re: International Walk Listings|
I bookmark any good site that I find on hiking. This one might have some good information for you - http://www.ava.org/
It is the American Volkssport Association, a national group for walkers. But there are links to international events at the bottom of this page: http://www.ava.org/walk/cal.htm
If I had a day to explore from Vienna, I would take the train to Salzburg. Hiking around there is wonderful and the city is one of the gems of Europe.
