A great addition to the city, a 3 day pass costs just €5. The first half an hour of use is free which should cover most of any journeys you make. If you make a journey longer than that you are charged, but these fees are fairly cheap. Purchase your ticket from selected terminal, the list is available on their website. Dublin city centre is compact compared to other cities, therefore these are ideal if you are ready to use some pedal power! While there are many cycle lanes in Dublin, the infrastructure is still developing so take care on your travels. Dublin has enacted bye laws which penalise cyclists for breaking red lights, cycling the wrong way up streets and other offences.
