I prefer northern Italy and southern Austria. The mountains are just beautiful. Brenner Pass is awesome. Check out the Imst bike path in Austria.
Lago Garda is very pretty, as well as Como. Near Comon is Bellegio and near Bellagio is the La Madonna del Ghisallo La Madonna del Ghisallo ? the Patron Saint of Cycling | Cyclingnews.com . Tried to make the ride twice in two different trips and was rained out twice. I mean pouring cats and dogs kind of rain.
