I think it was about 1976 - or there abouts anyway.
climbed last century with Colin & Ken then repeated in the new millennium with Ken and Peter M. (18/7/04 - his first ever rock climb - and he thought we were just taking him for a walk!!) great fun.
After a day tutoring on Tryfan Fach, I did this route with Lowri Roberts, a great end to a great day.
Climbed it with my brother Joe in August 2009.
