Hi Katherine,
I would say that a mix of the Ireland.com website and Google searches should give you a good list of the festivals that happen in Ireland. For example,
this Community post has a breakdown of some of the unmissable events on the island of Ireland, while the
What's On page is also very handy.
The Irish Times has also done a
very comprehensive guide to Irish festivals in 2025, as has the
Irish Country Magazine.
Regards,
Eoin
