Another necessary and important element of visiting northern Italy is knowing how you will get around. Northern Italy is the most developed part of the country, so transportation is easily available and can take you almost anywhere.
Northern Italy, however, is partially made up of the Italian Alps, which presents a problem for train travel. While you can easily get from city to city and even cities using regional trains, going through the mountains will mean there will be fewer stops and train options, or there may simply be no choice at all.
I recommend anyone visiting the Italian Alps to either rent a car or book a tour that handles transport throughout the day. Traveling by bus is also an option, but comes with its own challenges: first, understanding regional bus routes in a short period of time, and second, using the buses means you’ll be dropped off at one location and won’t have much freedom of movement .
