Like much of Europe, Ireland has a good public transport system. It’s easy to travel around the major cities (and the country in general) on buses and trains, benefitting both commuters and sightseers. Rental cars are inexpensive to hire, meaning you can readily access the more rural parts of Ireland too. The country has five international airports with direct flights to Europe, the USA, and a host of other countries. This puts you in the convenient position of having cheap, reliable transport links on your doorstep.
