Stock Ghyll is a tributary of the River Rothay, draining eventually into Windermere. It has a heavily industrialised past and once powered twelve watermills. It descends through a series of waterfalls to the centre of Ambleside where many of the old mill buildings whose wheels it used to turn can still be seen. The mills closed long ago, and most have now been demolished or been converted for other uses; some are used as shops.
