Hei Cian,
Yes, the UL wall is still there, but relocated to another building. The building is right across from the UL Arena, the old maintenance building. Haven't been there since last year. Last year I've joined as a non-student for the winter months and I think they've charged me 30 euros or something. As for the quality of the wall, you'll be the judge of that. I live in Ennis, so I rarely go there so decided that this year, instead of going to Limerick, I would use the diesel to head to the Burren and do some night bouldering as long as it's dry.
