With Leap Card, if you make lots of trips with your Leap Card in 1 day or 1 week (Mon-Sun) on Dublin Bus, Luas, DART and Commuter Rail, we’ll automatically cap the price so you don’t spend any more than you need to. Once you reach a cap, you can travel for free for the rest of the day or week on applicable services. All you have to do is Tag On and Off as normal, but your Travel credit won’t be charged.
