Hi Mike,
Sounds like a delightful trip you're planning!
One charming town you might consider stopping at on your way from Dublin to Killarney is
Kilkenny. It's a picturesque medieval town known for its well-preserved historic buildings, including Kilkenny Castle and St. Canice's Cathedral, with no shortage of great pubs. The train journey from
Dublin to Kilkenny takes around 1.5 hours, and there are frequent services throughout the day.
Be sure to check out our
accommodation search, I have pre-filtered Kilkenny for you.
Let me know what you end up choosing as a stopover and if you have any other questions,
