Ireland transportation advice needed

Look on Bus Eireann for the buses- https://www.buseireann.ie/

Shannon to Ennis- Service 51 to Galway at 54 minutes past each hour from 0754 (30 minute journey) or 343 every 2 hours on a Sunday from 0716, 40 minute journey

Ennis to Doolin Bus 350- at 1030, 1230 and 1430 for the just over 1 hour ride returning at 1149, 1449 and 1649

Trains Ennis to Doolin- see Irish Rail- https://www.irishrail.ie/Admin/IrishRail/media/Timetable-PDF-s/Heuston-timetables/02_dublin-limk-ennis.pdf

all trains change at Limerick or Limerick Junction-
0650 arrive 0955 (change at Limerick Colbert)
0740 arrive 1056 (change at Limerick Colbert)
1000 arrive 1256 (change at Limerick Junction)
1142 arrive 1457 (change at both Colbert and Junction)
1325 arrive 1655 (ditto)
1501 arrive 1759 (ditto)
etc

Many people would suggest taking the Dublin Coach #300 which runs every hour from 4am, takes 3hrs 30 minutes, and terminates at Bachelors Walk, literally across the bridge from Trinity College Dublin- https://www.dublincoach.ie/all-timetables/route-300-m7-express

From Shannon airport there are direct buses to Ennis taking 30m: https://national.buseireann.ie/ and https://www.expressway.ie/routes-and-timetables.
From Ennis to Doolin Bus Éireann has a direct bus taking 1h 15m. There are also direct buses from Ennis to Dublin taking 3h 30m. You can also take a train that requires a connection: https://www.irishrail.ie/en-ie/.

Thank both of you !

We recently arranged transportation for four adults from Galway to Doolin (150e) and Doolin to Shannon (120e) with John Sheedy at https://www.atlanticwayexcursions.ie/
I realize that’s not your route but if you decide to arrange private transportation for a part you can email him for a quote. He was easy to
plan with. on time, and gave a little “tour” along the way.

Renee, thank you!
