The Sett Valley Trail is a 2.5-mile (4.0 km) cycle- and bridleway in Derbyshire, England, linking the village of Hayfield and the town of New Mills (via Birch Vale and Ollersett). It runs along the lower valley of the River Sett and follows the trackbed of a former branch railway line from New Mills Central to Hayfield, which opened in 1868 and closed in 1970. The line was purchased from British Rail by Derbyshire County Council in 1973. The station buildings at Hayfield were demolished in 1975, and an information centre, picnic area, car park and toilets built on the site.
