All child Leap Card holders, aged between four and 18, can travel free on any Leap Card service for the next fortnight.
The scheme, running until August 7th, was announced by Transport Minister Shane Ross and CEO of the National Transport Authority (NTA) Anne Graham.
The free travel will automatically apply when using a child Leap Card on the following services:
The promotion hopes to encourage families, children and teens to use public transport during the school holidays, and to get out and about.
Announcing the scheme last week, Minister Ross said: "This is a fantastic initiative from the National Transport Authority which I hope will encourage lots of families with young children to avail of public transport for their summer outings."
"The Leap Card has been hugely successful due to its convenience and the value for money that it offers."
"This promotion will enable Child Leap Card holders to travel free on Leap Card services for a fortnight during the height of the summer season so I hope that families will make the most of this opportunity to make happy summer holiday memories."
