In reply to Tamati:
Often used by novice climbers but as others have said it can be cold in winter. If in the area why not pick up a guidebook from Inglesport. Chapel-le-Dale crags (a bit further up the valley) can be slightly more sheltered.
Also check out Tow Scar (see Leeds wall database)as it is less polished.
If weather is too windy then Gigglewick is not too far away and has some easy sport routes - (again see download from Leeds Wall)
