In reply to nicky79:
All of the following crags are accessible enough for an afternoon or evening's climbing. I regularly visited all these when I lived in crewe.
If you want local bouldering heighly castle about 8 miles from crewe towards Keele is good and hard - in the roaches guide I think. Grinshill a few miles north of shrewsbury is another good bouldering/micro routes type area (in the west midlands guide and possibly the new nesscliff guide). The whole Eglwyseg valley above Llangollen is superb and very beautiful. Maeshafn and Pothole Quarry near Mold are enjoyable and not too far (all in Clwyd Rock). Llanymynech and Pandy Outcrop (near Oswestry are also not a long drive) - not sure which guidebook they are in now.
Believe it or not if you get a sharp exit from work, drive quickly and take your mountain bike you can always grab a route on cloggy on a midweek evening after work! Did Longlands and Great slab that way for two memorable excursions Racing down the snowdon path in the evening gloom on your bike (headlights are unethical) in an attempt to make last orders is real fun! Places like The Ogwen Valley and The Llanberis Pass are no problem for a summer's evening and between them have the best part of a lifetime's worth of climbing.
Crewe is actually a good place for a climber who doesn't mind a bit of travelling, within two and a half hours you can be climbing anywhere from Avon Gorge or Wye Valley in the South via Mid wales, Clwyd Rock, The entire Peak District, Yorkshire Dales or The Lake District in the North, it is just a pity that to get to the peak crags often involves negotiating Stoke and then some poor roads making for surprisingly long travelling times given the distances involved.
Have fun
