Airedale is a geographic area in Yorkshire, England, corresponding to the river valley or dale of the River Aire. The valley stretches from the river's origin in Aire Head Springs, Malham which is in the Yorkshire Dales, down past Skipton on to Keighley, Bingley and Shipley through to Leeds and Castleford and on to join the River Ouse at Airmyn. This valley is of great topographic significance as it provides low-altitude passes through the mid Pennines to the west coast known as the Aire Gap.
