Thanks. Probably our favourite camping spots of the trip, despite the flashing lights!
We were there for two weeks, but it wasn't nearly long enough. But isn't that always the case?
Of the campsites we used, Wavecrest was the nicest by far, great location and the facilities were in good condition and clean.
Mannix Point was okay, nice waterside location and handy for the Skellig boats. In general, the campsites we used were fine, but nothing special. They all charged for showers and in general we found camping in Ireland to be expensive. The only one I really didn't like was in Wexford (just the other side of the bridge), but it was close to the ferry terminal at Rosslare, so served a purpose.
Away from the Ring of Kerry we found wildcamping easy and in nicer locations than the campsites. There are also a few Aire type places dotted around. We used the one in Cobh (no facilities, but toilets in the museum during opening hours and public toilets near the Titanic Experience). The train line is just behind it, but there aren't too many trains overnight.
