These 18 sport climbing crags are, with the one exception of Tyddyn Hywel, situated between junctions 16 and 31 on the A55 and a short hop from the expressway. They are only one and a half hours from Manchester and three quarters of an hour by car from Llanberis and Gogarth. Easy route finding, technical climbing, and bolted routes maes for a fun day out. It's a great way to bag a few routes on the way back from Anglesey or Snowdonia or enjoy a full day of varied and fun climbing with short walk-ins.
