I am in Ireland presently with my adult daughter. In case any of this might be of use to you...........We met each other at the Dublin Airport after arriving from SF (me) and DC (her). Took an easy airport express bus ride that practically dropped us right outside our Dublin hotel.
Dublin- We stayed two nights at Wynn's Hotel. It is centrally located on Abbey St, just around the corner from O'Connell St. Wonderful two night stay there. Highly recommend on all counts. EPIC, immigration museum is a must do (IMO). Book of Kells and The Long Library was quite informative and certainly of great historical import, but I felt like cattle being moved along through the exhibit. It was packed in late September, so I can only imagine the crowds next summer. No air conditioning and with all those people it was uncomfortably warm, correction, it was actually HOT inside.
We went back out to the airport and picked up our rental car. and then drove from there to our friend's home in Annagry, County Donegal. Wow, wow, wow, is all I can say. If you prefer cities and not venturing so far north, then this area would not float your boat. I know your title states SW Ireland, but if you want to get away from heavily touristed areas, this would do it (particularly with the crowds in the summer). The people, the scenery, the food, everything was absolutely wonderful. Malin Head, Slieve League, Tory Island, little towns like Andarra. New recently opened whiskey distillery, Croithli-beautiful historic building, delicious whiskey and a nice stop en-route to or from Glenveigh National Park. Doagh Famine Museum- fantastic!
Next stop was, Westport, County Mayo. We stayed in a fabulous Airbnb x 3 nights that was right in town. Lovely charming town. Westport Manor House, Creigh Patrick, Ankyll and Clare Island. Because it was off season, they were closed, but the Lost Valley Tour would have been on our to-do list.
Ennis and the Temple Gate Hotel was next with a stop in Galway that evening. Really disliked Galway, but that might have been because it was loaded with American tourists and big tour groups for the short time we were there.
With Ennis as our home base, we drove over and spent a day in The Burren. We had an absolute fabulous guided walk with Mary O'Dea, hiddenburrenwalks.net. I know RS recommends two others, but this is a woman enterprise and she is an 8th generation resident of this area. Mary knows the history of the area/it's peoples, as well as the unique ecosystem. Burren Perfumery is NOT to be missed either. (Mary met us there). PBS has a two part documentary on The Burren that I highly recommend watching as well. I would have gladly spent another day on The Burren.
We are now on the Dingle Peninsula, staying at a sweet B and B just outside Dingle Town. Dingle is very busy this weekend due to the annual Food Festival. Which we will be checking out later today. Lovely hiking here as well.
Happy travels!
