We are an older couple who have no interest in big cities, nightlife or beaches. We enjoy walking, nature, art, cultural experiences, good food and quiet and slow travel by public transportation. We speak some Italian and prefer more "rustic" accommodations. What would be the best itinerary for an 8 day visit to Sicily in late September? Thanks so much. We will be coming from London and can fly into Palermo, Trapani or Catania.
