Hi Sharon, welcome to the community!
Sounds like you have a great trip coming up. Have you got some fun activities planned in Dublin?
Kildare could be a lovely possibility for you to spend a night in after Kilkenny. There are the beautiful Japanese gardens and a brilliant heritage centre to name just a few of the
great things that you could do! If you would like as little traveling as possible, Kilkenny to Kildare will only take around 1 hour 40 minutes on the bus and then just another 1 hour back to Dublin from Kildare. You can check timetables out on the
Bus Éireann website.
Alternatively, if you didn't mind a bit of extra travel you could travel to Wicklow to see the stunning Wicklow Mountains. The route is not as direct and you would be a little longer traveling, but it would really be worth it! You should check out this post from some of our other community members on ways to get from
Dublin to the Wicklow Mountains.
I'm sure no matter where you choose, you will have a great trip!
