The River Wye is a limestone river in the Peak District of Derbyshire, England. It is 23.9 miles (38.5Â km) long, although it is widely quoted as being 15 miles (24Â km) long, which refers to the section within the National Park. It is one of the major tributaries of the River Derwent, which flows into the River Trent, and ultimately into the Humber and the North Sea.
The river rises just west of Buxton, on Axe Edge Moor, and the flow is augmented by water which passes underground through Poole's Cavern before rising at Wye Head. The two sources join as they cross the Pavilion Gardens in Buxton. The river then flows east through the dales of the Wye Valley, along a route roughly followed by the A6 road. It enters the Peak District, flows just south of Tideswell, then through Ashford in the Water and Bakewell, passing to the south of Haddon Hall, before meeting the River Derwent at Rowsley. The main tributary of the river is the River Lathkill, which enters approximately one mile from its mouth.
