3. Grenoble
Grenoble is mostly known as a center for science and technology, but it is also blessed with astounding natural beauty. Embraced by the mountains of the Parc Naturel Régional de Chartreuse and the Parc Naturel Régional du Vercors, the city is set on the bank of the River Isère and boasts many scenic vistas. This “capital of the Alps” in southastern France hosted the 1968 Winter Olympic Games. Its cobbled streets, open-air markets, chi-chi cafés and ooh-la-la boulangeries add to its charm.
