Thames Path
The Thames Path is a National Trail, first proposed in 1948 opened in 1996, following the length of the River Thames from its source near Kemble in Gloucestershire to the Thames Barrier at Charlton. It is about 184 miles (296 km) long.
The entire length of the path can be walked, and some parts cycled. Most of the path uses the original towpath but in some places this is not possible. The main reason for this is that towpath traffic used to cross the river at several points using ferries, but apart from Shepperton to Weybridge Ferry these no longer operate. This means that in several places such as Shiplake, Whitchurch-on-Thames and Moulsford, there are diversions away from the towpath. At other places, there are replacement connections. An example of this is at Hurley, where the Temple Footbridge was built in 1989.
Some parts of the Thames Path, particularly those west of Oxford, are subject to flooding during the winter months. The river is tidal downstream from Teddington Lock, and parts of the path may be underwater if there is a particularly high tide.
