We have all been on city breaks and bought a bus tour ticket to get a big picture of the city. Well, if you are thinking about doing that in Dublin then you must consider the Viking Splash Tour.
Instead of a bus, you travel in an old US Army amphibious vehicle; that means it can travel on road and in water. And it does!
The tour takes over an hour passing all the usual main attractions (you cannot get off - there are no stops on this tour) before entering the water for a different view of the city.
Book in advance, bring rain gear and don't forget to scream!
