In 2019, we took a hiking tour of part of the Dingle Penninsula. Had a fabulous time. We used Hillwalk Tours - they handle the luggage and the B&Bs. The only problem we had was the first day when we thought we were going to be ciimbing a hill, but it was more like a mountain (we screwed up as we treated "meters" as "feet" on the map).
Had fabulous views and mostly good weather. Each time it rained, it stopped shortly. The one time the rain looked like it was going to last for a while, we were near the Blasket Centre, so we spent a dry hour learning all about the island.
We had good breakfasts, and there was always a pub for lunch about 4 hours into each hike. We were at the same B&B for two nights and had excellent pub dinners as well.
Companies like Hillwalk Tours are extremely helpful if you haven't done lots of hiking and want to give it a try. They also have two or three different levels of hikes, so you can start easy and go from there.
