Dingle is a great place to visit, I've never been in the summer, I suspect there might be too many tourists for my tastes but without tourists it would be a very different place. Flaghertys Bar is a great place for music and take a trip over the Connor Pass, the view from the top is brilliant. Murphys Bar over at Brandon is one of my favourite places ever and Murphys at Ballyferriter is well worth a visit. Overall the Dingle peninsula is a microcosm of everything that is good in Ireland, people, scenery, pubs, antiquities etc etc
Have fun

Cheers
