Just like in other major cities across the world, Dublin has its own underground train network. This is a great way of getting around the city, as it offers the quickest and most efficient way of travelling to other areas of the city. The 2005 transport plan from the government started the first two lines, and now the network has become one of the most popular forms of transport for locals and tourists. The Metro North line runs from St. Stephen’s Green to the airport, and later reaches the Broadmeadow Estuary.
The Metro West is also available, and this runs from an intersection within the Metro North (a little south from the Santry airport), and later reaches Tallaght, running through Liffey Valley and Clondalkin. So before you set off on your journey, see which sights fit with this line, and get the train instead of the bus! It’s pretty inexpensive and more efficient than other forms of transport within the city.
