In reply to Parrys_apprentice:
The Ice Factor is great, plus excellent value. I went to the one in Leeds a few times before it shut down, but it was cheaper for me and a friend to drive to Kinlochleven (6hours), do two hours of climbing, then drive home (another 6h), than it was for an hour at Leeds :-P
I especially like the fact you can climb but because it's indoors you don't have to wear bulky clothes, thick gloves etc.
