Hmmm,
I'm not sure which centre you are referring to ,but Cappanalea,Outdoor Adventure Centre,near Caragh Lake is halfway between(approx) Killarney & Waterville.It's the only 1 I've heard of.Was there 16 yrs ago-great time
I was there years ago too and yeah, it was brilliant. Even raining and cold. We went to bed every night exhausted and aching. Orienteering, canoing, rock climbing, abseiling and windsurfing. Maybe there's more.
