Tickets for Rome Hop-on Hop-Off Boat Tiber Cruise. One of our BESTSELLERS! We love boat trips. We think they are one of the best ways to explore a city. You simply sit back, relax and enjoy the journey and get a view and different angles than you would from the land. This one is no different. Lasting an hour, but with hop-on hop-off options (and different durations depending on the ticket you choose) you will see sights including Vatican City, the Pantheon, Campo de’Fiori, amongst others. You can also choose a 24-hour option to give you more time to enjoy it as well and hop-on hop-off where you like. They sail every 30 minutes, so you won’t be waiting for long. A great choice.
