The Hope Valley is a backwoods centred on the town of Hope, Derbyshire in the Peak District in the north Midlands of England. The name also applies to the post community that includes the bordering villages. Although the Hope Valley appears to be a solitary valley, the name of the river changes a number of times. The head of the valley exists listed below Mam Tor at Castleton. From here, the Peakshole Water moves to Hope, where it gets in the lower reaches of the River Noe, which has streamed from Edale. The Noe then streams to Bamford, where it goes into the River Derwent, which has actually travelled about ten miles from Bleaklow. The valley is now technically the Derwent Valley, but the term "Hope Valley" is still used as the Derwent moves via Hathersage and Grindleford. Other streams in the area consist of the Burbage Brook, which runs down from Burbage Valley with Padley Gorge and right into the River Derwent near Grindleford station. The area is a popular visitor location, especially as the Hope Valley Line railway from Sheffield to Manchester runs through it, from the western end of the Totley Tunnel near Grindleford to the eastern end of the Cowburn Tunnel near Edale. In the centre of the valley is a long-standing concrete factory, the UK's greatest, run by Hope Construction Materials. It is somewhat infamous locally because it is a popular commercial operation in the middle of a National Park as well as is extremely noticeable from several places. Nevertheless, the factory gives useful neighborhood work outside the tourist market.
