Make sure you pack seasickness medication if anyone in your group gets seasick. Pack hats, sunscreen and bottled water, along with bathing suits and towels.
The boat rides can get very crowded as the day progresses, so try to catch the ferry first thing in the morning to begin your day. If the boat is too crowded, the train is always another option for transportation. Tickets for the ferry can be bought at the dock.
Start your boat journey early in the morning, especially in peak season, to avoid the large crowds. The sun can be brutal in the afternoon.
The ferry does not run throughout the winter. Make sure you check the ferry's website for operating times during your visit. Rough seas can also cancel ferry rides.
Children under 6 ride free on the ferry with a paying adult. The villages each have many gelato and sandwich shops. Grab a picnic lunch to enjoy with a view!
