Pass: warm up at the Cromlech roadside face, tick The Edge Problem and Cave Route; then head over to the Pont y Gromlech slabs and nip up The Seam. Trot up the scree path for Gav's Big Problem (knee bar start on the right); then head straight across to the Barrel (ticking The Bogey on the way if you fancy it). Do Prob 3 and The Minimum. Next: The Grooves Boulder. Boysen's Groove, The Witch and Paul's Bulge are all essential. Up left to do Northern Soul, Arse Soul and Kris' Groove; then up to The Meadow for Killer Weed and Meadow Roof, and Lordy, Lordy on the Dome. Back down to do everything you can on the Wavelength block and finally finish off on the Utopia block. Collapse into Vaynol for many pints.
Also prepare to climb below your level as welsh grades are particular harsh on first aquintance IMO
