The Sett Valley Trail is a 2.5-mile (4.0 km) shared-use path in Derbyshire, England, linking the village of Hayfield and the town of New Mills, via Birch Vale, Thornsett and Ollersett.

The path follows the trackbed of the former branch railway line from New Mills Central to Hayfield, via Birch Vale, which opened in 1868 and closed in 1970.

[1] The line was purchased from British Rail by Derbyshire County Council in 1973 and the station buildings at Hayfield were demolished in 1975.

An information centre, picnic area, car park and toilets have now been built on the former Hayfield station site.

[3] The Pennine Bridleway[4] and Peak District Boundary Walk[5] follow the section of the trail between Hayfield and Birch Vale.
