The River Holme is a tributary of the River Colne. From Digley reservoir, it flows north east through Holmbridge and Holmfirth. It flows north-north-east to Thongsbridge and Brockholes before turning north and reaching Honley, Berry Brow and Lockwood. It then proceeds northwards and joins the River Colne just south of Huddersfield town centre at Folly Hall.
The Huddersfield Narrow Canal follows the course of the River Colne through the valley, as does the Huddersfield Line railway, and the A62 road. The Narrow Canal passes the University of Huddersfield campus. It runs just under 20 miles (32 km) from Aspley Basin at Huddersfield to the junction with the Ashton Canal at Whitelands Basin in Ashton-under-Lyne. It crosses the Pennines by means of 74 locks and the Standedge Tunnel, which is Britain's longest canal tunnel.
