Hi Bénédicte,
The Irish Hot Air Ballooning Championships is confirmed for September. It will take place in Birr, County Offaly, from Saturday 24th to Friday 30th September 2022. Birr is located an hour away from Kilkenny.
For now, that's all the details I could find in these articles from the
Ballooning Association and
Flying Ireland. Keep an eye on these resources for any updates!
Are you planning to visit during that period of time?
Je vous souhaite une excellente soirée !
Marine.
