Many years ago I got tipped off by my almost namesake Darragh Flanagan that the quarries on the lower slopes of Three Rock might contain some bouldering, I didn't think much of it at the time but obviously stored it away deep in memory. A while ago I was using Bing Map's birds eye view and checked out Three Rock and some of the quarries that pockmark Three Rock seemed to offer some potential.
Yesterday I went to check them out. There are lots of mountain bike tracks but no bouldering. So now you know.
