In reply to Ourea:
I guess you could start at glaslyn then link in to central trinity which takes you the station! There are loads of gully climbs on the trinity face, central being the low grade super classic, in the pass again loads, parsley fern, sinister etc, Cwm llor also gas lots of steady gullys, broad gully probably the best of them with y gully left and right also nice, then pop across the road and tick the classics in Cwm idwall, plenty to go at!
