Main benefits of Killarney for a family that I would see:
- If the kids are into sport there's something for everyone - soccer, GAA, rugby, basketball, swimming, athletics, golf/pitch and putt, tennis; all less than 5 minutes drive away.
- Great for lots of other outdoor pursuits e.g. Orienteering, Hill walking, mountain climbing, cycling, rowing, horse riding.
- Lots of great pubs and restaurants.
- Generally regarded as a safe town.
Cons:
- Can get a bit overcrowded with tourists during the Summer.
- Gets twice as much rainfall as Dublin.
