We have a trip planned to/from Shannon in August.
We will have 3 nights in Adare, but the first 3 nights we are looking to rent a car and go somewhere within 2.5 hrs from Shannon airport.
I've done Ring of Kerry and Cliffs before and both were stunning, so at first research looked like Dingle or Aran Islands (via Doolin) could be of interest as well.
Would love firsthand recommendations. Will by myself, DH and 2.5 year old
