I intend to visit some cities in the Italian Alps (for ex: Belluno, Bolzano) but my greatest wish is in fact to visit the little villages inside the valleys (Siusi, Funes, and so on).
The problem is that I can't drive, and besides that, renting a car would be really expensive for me. I would like to know what are the best ways inside the valleys for transportation. Walking seems to be out of consideration, since the distance between Funes and Bolzano, for example, is about 42 kilometers.
Is there public transportation to the little villages? Is bicycle a good option?
