Good shoes, rain protection and binoculars
If you want to visit the old cities and might need to park “outisde” or walk from train/bus stations to your accommodation, I would recomment that you bring luggage on wheels or backpacks, they are easier to carry on the often cobblestoned roads. Definitely bring shoes with which you are comfortable for walking. Often, the roads are steep and often they have cobblestones. Your feet will be grateful in the evening. Bring warm clothes, even in summer, as the temperature in the valleys might get colder than at the coast. Umbrella or raincoat might be a good idea, depending on the season. I needed good rainprotection in April (2008). If you want to visit churches, bring something to cover arms and legs, as you might not be let in with unappropriate clothes. There are enough pharmacies where you can get medical supply. Bring translation for prescriptions. You might like to bring first aid...
