We had just barely enough time to do what what did. I knew it would be aggressive, and I knew we would be skipping (or just blowing through) worthwhile places. I made the strategic decision that 1) we were going to focus on the west coast and far southwest, which looked like the "best" parts of Ireland (to me - it's a subjective thing), and 2) we would catch the things we skipped or minimized on another, future trip. Those choices worked for us, others would make different choices and that's OK.
We flew in to Dublin, arrived mid-morning, immediately took a bus from the airport to Galway, arrived early afternoon.
We walked around Galway and took it easy that afternoon, since it was arrival day (=jetlag).
Next morning we took the tiny plane to Inish Mor (catch a cute but slightly funky shuttle bus at a hotel off the Main square in Galway, short ride to the airstrip, 10 minute absolutely THRILLING flight to Inish Mor, dropped at our BnB. We were there by mid-day, leaving us free (and ahead of most day-trippers who took the sloooow ferry). We walked into town, rented E-bikes, and pedaled off. Explored the island. Dinner in a local pub, slept.
Up early, breakfast @ BnB, pedaled off to explore more of Inish Mor. Dinner, sleep. Two really wonderful days
Up early, pickup for airport ride. Flew back to mainland (10 minutes from engine start to shut down). Shuttle to Galway center. Walked to car rental agency. Picked up our car. Drove off towards the south and southwest. Stopped several times (a couple ruined abbeys, castles, the Burren, some neolithic stone tombs, Cliffs of Moher...) drive drive drive, drive some more, eventually arrived in Dingle. That was a long day in the saddle, was very glad to get there. 3 nights at a lovely Dingle B&B.
Up early our first day there, did the loop around Slea head. Stopped many times, lovely dramatic scenery. After seeing the logistics of getting to Great Blasket Island, and seeing the island in the distance, we made a decision on the spot to go there next day.
Up early, out to Slea Head and the impossible little "harbor" (with the "sheep highway") at Dunquin for the Blasket Island ferry. Ferry to Great Blasket island. We hiked up one side of the island, back the other side, all of it unbelievably beautiful, green and unspoilt. I got a sunburn that day. Got back to the ferry just in time to catch last boat off the rock. Drove back to Dingle. Enjoyed a pint and live trad music in a hardware store, with vicegrips and saws stacked up around the musicians (great music!).
Up early, jump ini the car, headed for Portmagee, the jumping off point for Skellig Michael. Took the scenic route via Valentia Island (little ferry), including the western "half" of ROK, drove to our BnB on the outskirts of Portmagee. Slept there.
Up early, meetup with boat for Skellig Michael in Portmagee harbor (booked months in advance, but never a sure thing - boats only go when sea conditions are OK). Captain says weather's OK, we get on the boat and go. Spent a few hours with the birds. Amazing place. Back on the mainland, drove east, finished most of the eastern 1/2 of ROK, headed for Kenmare, checked in to our BnB there. Dinner, sleep.
