A towpath is a road or trail on the bank of a river, canal, or other inland waterway. The purpose of a towpath is to allow a land vehicle, beasts of burden, or a team of human pullers to tow a boat, often a barge. This mode of transport was common where sailing was impractical due to rapid current, tunnels and bridges, or unfavourable winds.
After the Industrial Revolution, towing became obsolete when engines were fitted on boats and when railway transportation superseded the slow towing method. Since then, many of these towpaths have been converted to multi-use trails. They are still named towpaths - although they are now only occasionally used for the purpose of towing boats.
Towpaths are popular with cyclists and equestrians because they are mostly flat and long. In snowy winters they are popular with cross-country skiers and snowmobile users.
Although historically not designed or used as towpaths, acequia ditch banks also are popular recreational trails.
