Hello, A reasonable journey for two weeks.
Dublin to Kinsale. These recommendations can make for along driving experience. Glendalough and St. Kevin's Church in the Wiclow Mountains south of Dublin would be on my list. You don't get to Cashel from there by accident. Or skip Glendalough and go to St. Bridgit's church it is on the N7 on your way to Cashel. Cashel is a premier spot. Not my favorite, but it is a premier spot.
Kinsale to Dingle. Beara Peninsula. It is below the Kerry Peninsula. Kenmare. Gougabara which is Saint Finnbar's place and is on the way to the Beara Peninsula.
Dingle to Galway. You can skip everything from Dingle to Tarbert where you can catch a ferry into a much lovelier place. Or keep going to Limerick. North of Limerick is the City of Ennis. best medieval high street outside of Dublin. Killinaboy, now that is aname...to the west of that village a road heads north. Google the area zoom in and this road has a sharp S cshape shortly after you turn on to it. This 'back' road takes you through pre-Irish Tiger scenery. Poulnabrone megalithic site. There are others along the way if you keep an eye for sign posting or just recognize them on the fly.
Galway to Trim...oh, oh. Clonmacnoise, a big deal. But are you sure you want to head toward Trim? The land north and west of Galway, Connemara, is spectacular. But maybe another trip. Near Trim is the Hill of Tara, the Boyne River Valley...quite nice. And New Grange...ruined by parking lot development. But is huge prehistoric place.
Dublin...Kilmainham Gaol. Buswell's Hotel for lunch with the members of Parliament. St. Michan's Church on Church St.
