The Huddersfield Narrow Canal runs south west from the Huddersfield Broad Canal in Huddersfield to the Ashton Canal in Ashton under Lyne, Greater Manchester.
It is 31 km (19.3 mi) long and has 76 locks. At its summit, it is the highest navigable waterway in Britain and it also features the longest canal tunnel in Britain, Standedge Tunnel (5,029 m / 16,499 ft).
It is part of the South Pennine Ring, a circular navigable boating route which crosses the Pennines twice. The Huddersfield Canal area is also a Site of Special Scientific Interest.
Walkers can ramble the length of the canal with a multitude of footpaths splitting off in all directions for further exploration of the Pennines.
