Looks like you're planning a trip to Ireland! 😄
The best option
is to take the bus 300 (Dublin Coach) to Limerick and then to Ennis and from there take the bus 350 (Bus Eireann) to Doolin.
You will travel in County Clare
which is on the Wild Atlantic Way and there are so many places not to be missed.
We advise you not to miss the Burren and the Cliffs of Moher!
County Clare is also home to gorgeous spots such as Lough Derg and the River Shannon, as well as leafy villages like Mountshannon and Killaloe.
If you want some other advice you can reply to this thread.
Have a great day! ☘️
