The River Sett is a river that flows through the High Peak borough of Derbyshire, in north western England. It rises near Edale Cross on Kinder Scout and flows through the villages of Hayfield and Birch Vale to join the River Goyt at New Mills.[1] The River Goyt is one of the principal tributaries of the River Mersey. In the past, the river was known as the River Kinder; the modern River Kinder is a right tributary of the Sett, joining the river at Bowden Bridge above Hayfield.[2]
The 2.5-mile Sett Valley Trail follows the trackbed of the former railway line along the valley between Hayfield and New Mills.[3]
The river's Environment Agency pollution classification changed from good to moderate in 2014.[4]
