West Cork is one of the most scenic parts of Ireland. The main Towns in this area would be Bandon, Kinsale, Skibbereen, Glengariff and Castletownbere. I dont know it really well personally - apart from Kinsale, but hey, I can always visit some other time!
This is a far off shot of Bearhaven Island off in Bantry Bay...the picture speaks for itself. No nightlife or discos within 100 miles. To me, Ireland is about sweeping vistas, deep thoughts and inner dialogue..that is possibly why Ireland has so many gifted writers.MY TIP?...see the cities for sure...but just keep in mind Ireland is about its rugged rural charm.
