Reaching Your Destination
I recommend flying into Milan, Florence, or Pisa. Flights need to be arranged on your own, but I can suggest a travel agent. Since our time together is only five full days, I suggest you plan to see another part of Italy either before & after our time in Cinque Terre. You can take the train from any of the cities to La Spezia & change trains there for a local train to Monterosso. If you prefer, I can give you information about a private shuttle bus directly to the hotel. One tour I did, the guests opted to take a shuttle from Florence, as all ten of them happened to start there and it was much more convenient than changing trains with luggage.
You can choose to fly to any Italian city, but I suggest Milan, Pisa or Florence. These destinations are 1 1/2 to 3 hours from Cinque Terre. I will give you specific instructions about taking the train to Monterosso al Mare. The hotels are a short distance from the train, about 10-15 minute walk. I suggest luggage with wheels and packing light. I usually arrive a couple of days ahead of the tour to confirm arrangements for the week. I will see you at your hotel and the fun begins. Welcome to the Italian Riviera!
