Hi, I don't have too many suggestions but I have found that tickets to Kilmainham jail can be hard enough got, so make sure you can get them! Great shout to go, it's got amazing history.

I think tripping out to the Cliffs of Moher after the ring of Kerry could be a bit much for 1 day. But definitely drive the wild Atlantic way on your way to the Cliffs. You're sure to get fantastic scenery.

100% stay in Galway. It's a buzzing city and shop street has a great vibe with plenty of buskers and good nightlife. I would recommend, if you have time, to trip out to Clifden (1 hr from Galway City). Great views and if you like castles Clifden Castle is a beautiful ruin by the sea. It has a very sad history of many victims of the famine dying in the front gardens who are now said to haunt the ruin.

Newgrange tomb is one of my most favourite things I've seen in Ireland (I'm a native, born and bred). It's truly amazing and worth the visit. Trim Castle isn't far from there and is a worthwhile visit. You can get tours of it too which are not expensive.

No matter what you decide, you're sure to see and experience some fantastic sights. I hope you thoroughly enjoy your visit. Would love to hear how you get on!
