There is an extensive network of public footpaths and canal towpaths. Some trails follow the towpaths of canal systems. There is a behavioural code for considerate riding on London's towpaths. Mules and horses pulled the packets along the towpaths. It is long and has twin towpaths throughout. Parts of the Catharine Valley Trail are built along old Chemung Canal towpaths. Many of the canalway trails follow former towpaths. Since then, many of these towpaths have been converted to multi-use trails. As for the Stagecoach for the mail, the boats were pulled by horses on towpaths. In return, he had to maintain the towpaths by which the barges were drawn upstream. This included making new cuts, and creating towpaths on both sides of the river. The scenic towpaths cut across roads and railways in the area, providing a distinct viewpoint. Teams of mules walked on towpaths beside the canal and pulled the boats. Gallo-Romans used the towpaths () and the wind to move upstream. Eventually, the canal sides and towpaths (walkways for those pulling barges) were removed.
