Useful information about the flight from London Heathrow to Dublin

Ancient Capital Dublin

Founded in the 8th century by Viking settlers from Scandinavia, Dublin is a city steeped in history and mystique. Its age is evident not only in some of the historic architecture, but also in the city layout itself; the streets are winding and delightful, testament to an age before grid systems. Don't let this fool you, however; Dublin boasts much historic architecture, but its young population, vibrant night life and friendly atmosphere make it an excellent destination.

Best time to travel, weather and events

Ireland is a lush country, famous for its greenery and rainbows. These are a result of its mild, wet climate, with temperatures ranging from lows of -4°C in the winter, to 25°C in summer. Dublin is a fantastic destination year-round, with a variety of festivals, museums and other destinations to enjoy. Not least of these is St. Patrick's day, arguably the most famous national holiday in the world. Of course, for those arriving at other times of the year, there are a variety of cultural festivals to try, for instance the Dublin Fringe Festival, a must for any comedy loving travellers.

Important information prior to leaving

Dublin has transformed in the last twenty or so years and boasts a well-integrated public transport system. It has ranked in at number 15 on the Copenhagen index for bicycle-friendly cities, and is undergoing several upgrades to make both cycling and public transport a better option for commuters. Cost of living in Dublin is relatively high, though still less than London and Paris, though many of its attractions are affordable, while National Museums are free of charge to enter.

Getting there and around, hotel tips

Dublin Airport is located in Swords, approximately 10km north-west of the city centre. The Aircoach, which also offers routes to Cork and Belfast, runs every 15 minutes and will get you to the City Centre for €9 single or €15 return. It takes around 30 minutes, though if you would like to arrive quicker, Dublin Bus route 747 takes you via the Dublin Port tunnel and is cheaper, though not as comfortable. From the City Centre, the LUAS and Dublin Bus offer services that will put everything in reach relatively easily, though many attractions are within walking distance.
