Best things to do and see in Ireland

If you’re looking for cheap flights to Ireland, chances are you’re coming from some of the major cities in the US, like Atlanta, Chicago, Dallas, Los Angeles, Denver, or Washington DC. These are the cities with the busiest international airports that you are most likely to depart from. Therefore, you can use the momondo search engine to check the total duration time of your nonstop or connecting flight. For example, it is about a 10h 52min flight from Los Angeles Intl Airport to Dublin’s main airport known as Bernd Biege. If your flight takes off from Hartsfield-Jackson Atlanta Intl Airport, it will land in Dublin in about 8h 23min. An Ireland flight from Dallas/ Fort Worth Intl Airport will take about 9h 27min and around 7h 51min for travelers departing from the Chicago O’Hare Intl Airport.

Yes, major carriers such as United Airlines, Lufthansa, British Airways, Iberia, and Aer Lingus provide direct Ireland flights from the US. If you’re looking for cheap flights with potentially short hauls, your best option would be the 7h 25min, Chicago O’Hare International route to Dublin Airport aboard American Airlines, Aer Lingus, or United Airlines. No nonstop flights are currently departing from Atlanta, Miami, Dallas, Los Angeles, Huston, or Washington DC. We recommend using momondo to compare numerous multi-city flights to Ireland and find a connecting airfare that fits your travel itinerary.

Ireland boasts of natural beauty, medieval castles, islands, and many city nooks and crannies to explore. And while there is no subway or underground system, Downtown Dublin is compact, making walking the most efficient way to get around the city. Even so, Dublin has an easy-to-use and extensive public transportation consisting of the bus, LUAS, DART, and train network at the ready. A double-decker style Dublin bus is the best transportation option for those who want to navigate the city like a local. In this case, we advise that you get a bus map upon your arrival in the city. Note that while you can purchase tickets on the bus, you can only do so using euros. On the other hand, when you want to experience the sights and sounds of the Irish capital city, like a visit to the Saint Patrick’s Cathedral, Dublin Castle, Trinity College to see the Book of Kells, or the famous O’Connell Street, consider taking the privately-owned hop-on-hop-off tourist bus. Also known as Dublin’s LUAS is a fast tram that runs along a dedicated track to transport travelers to the suburbs, while DART is for those traveling from north to south along the coastline of Dublin Bay. Taxis are part of Dublin’s transport system, and we recommend taking one particularly at night or to and from the airport.

Travelers must have a valid passport to enter Ireland, and citizens of the United States are allowed to enter and stay in Dublin visa-free for 90 days. Note that while your passport must be valid during your travels, you are exempt from the mandatory six-month validity period rule according to Ireland’s passport requirements to Americans. If you’ve found a competitive airfare to the Emerald Isle and are ready to head to your destination, before boarding your plane, ensure that your passport contains at least one blank page for an entry stamp. Also, have a return ticket ready, including proof of funds to help cater for the entire length of your stay in Dublin.
