The Thames Path is a National Trail following the River Thames from its source near Kemble in Gloucestershire to the Thames Barrier at Charlton, south east London. It is about 184 miles (296 km) long.[1] A path was first proposed in 1948 but it only opened in 1996.[2]

The Thames Path's entire length can be walked, and a few parts can be cycled. Some parts of the Thames Path, particularly west of Oxford, are subject to flooding during the winter. The river is also tidal downstream from Teddington Lock and parts of the path may be under water if there is a particularly high tide, although the Thames Barrier protects London from catastrophic flooding. The Thames Path uses the river towpath between Inglesham and Putney. Historically, towpath traffic crossed the river using many ferries,[3] but crossings in these places do not all exist now and some diversion from the towpath is necessary.

Description and access to the river[edit]

The general aim of the path and the object of occasional path changes is to provide walkers with a pleasant route and access to the river, as much as possible. The Thames Path provision naturally falls into three distinct areas.

Source to Lechlade[edit]

The Thames Path uses all available riverside rights of way between the traditional source of the river in Trewsbury Mead and Inglesham, but is unable to run alongside the river in several places. The Thames Path starts beside the monument for the source of the river and follows the stream down the hill towards Kemble. On the stretch between Ewen and Somerford Keynes you pass through fields and there are a number of watermills. The path then follows the river through Cotswold Water Park to Ashton Keynes where the river divides into a number of streams; the path partly follows one of these and rejoins the main river by Waterhay Bridge. The path wanders to and from the river amongst more gravel pits until Hailstone Hill, where a branch of the Wilts & Berks Canal formerly crossed the river on an aqueduct. The path then follows the river into and out of (but not within) Cricklade and all the way to Castle Eaton. The path next follows country lanes, a short stretch along a backwater to Hannington Bridge then goes across fields to Inglesham. In 2018 the path incorporated a section of permissive path alongside the river at Upper Inglesham.

Above Lechlade and below Ashton Keynes, the river is its natural self without the benefit of locks and weirs and so it is shallower, less well maintained, weedy and swifter, and the river level fluctuates, so flooding, including that of riverside paths is common. Today the Environment Agency manages the Thames between Cricklade and Teddington, and maintains the right of navigation for small boats up to Cricklade, however there is no designated towpath upstream of Lechlade. It is likely that the Thames Navigation Commission did not incorporate any towpaths to Cricklade, because the Thames and Severn Canal provided an alternative route for barge traffic, although sections of the footpath that run alongside the river around Cricklade may be older towpath.

Navigation with locks and towpath[edit]

The Thames Path uses the existing Thames towpath between Inglesham and Putney Bridge wherever possible. The Thames towpath owes its existence in its current form to the Industrial Revolution and the Canal Mania of the 1790s to 1810s. The Thames has been used for navigation for a long time,[4] although owners of weirs, locks and towpath often charged tolls. However, it was not until a little after the Thames Navigation Commission were enabled by a 1795 Act of Parliament to purchase land for a continuous horse path that the non-tidal navigation (and hence the towpath) was consolidated as a complete route under a single (toll charging) authority, upstream to Inglesham. This improved the ability of horse drawn barge traffic to travel upstream to the Thames and Severn Canal, which had opened in 1789.[5] The commissioners had to create horse ferries to join up sections of towpath (for example at Purley), as the Act did not allow them to compulsory purchase land near an existing house, garden or orchard. The City of London Corporation, who had rights and responsibilities for the Thames below Staines, from a point marked by the London Stone, had similarly bought out the towpath tolls of riparian land owners as enabled by a 1777 Act of Parliament. Although both development of the railways and steam power supplanted horse drawn boats on the non-tidal Thames from the 1840s, the towpath still exists little changed, except for the discontinuance of the ferries, some of which were still running even until the 1960s.

The canal entrance is the present day limit of navigation for powered craft and is one and a half miles upstream of the highest boat lock near Lechlade.[6] Today, between the canal entrance and Putney Bridge, the towpath still allows access by foot to at least one side of the river for almost the whole length of the main navigation of the river (but not mill streams, backwaters or a few meanders cut off by lock cuttings) since towpaths were only intended to enable towing of barges. The main exception to this is a stretch of river without any dedicated path in Home Park, Windsor. The Windsor Castle grounds were extended to include the riverbank by the Windsor Castle Act 1848, involving the building of Victoria and Albert bridges and the removal of Datchet Bridge. This accounts for the Thames Path's diversion from the river at Datchet. There are also two other short lengths of river missing access: between Marlow bridge and lock, and either side of The Swan public house in Pangbourne. Other than these exceptions, between Inglesham and Putney, the Thames Path only makes diversions from the remaining towpath due to the lack of a lock, bridge or ferry to cross the river in the original locations. There are also some lengths of river bypassed by navigation cuttings which are still accessible directly off the Thames Path at Sutton Pools, Penton Hook Lock and Desborough Island.

Temple Footbridge built in 1989 for the Thames Path

Historically, there have been replacements for towpath ferry crossings with bridges at Goring and Clifton Hampden and the path across the weir at Benson Lock (towpath ferry was upstream[7]). In recent times, crossings have been created for the Thames Path; the Shepperton to Weybridge Ferry was restarted in 1986, Temple Footbridge near Hurley was built in 1989, a footpath attached to Bourne End Railway Bridge in 1992 (ferry was upstream[8]), and Bloomers Hole Footbridge was built in 2000. No other replacement river crossings have been created for lapsed ferries, so the Thames Path has to divert away from the towpath to cross the river elsewhere, leaving some sections of towpath unused. Walkers can still use the towpath to visit lengths of riverside not on of the Thames Path, with two exceptions, where there are now isolated sections of towpath not connected by any public path (or ferry at either end). The first is 1km downstream of Mapledurham Lock, which accounts for the path's diversion from the river at Purley-on-Thames. The second and most downstream is a section of towpath requiring National Trust entry to Cliveden, which accounts for the path's diversion from the river at Cookham. Note that when Cookham Lock was built in 1830, Hedsor Water became a backwater and lost its towpath.

Cliveden from the River Thames

The Locks on the River Thames are pleasant places to visit on the Thames Path, and in summer some have facilities open for visitors. The locks at Cookham and Whitchurch are not on the Thames Path. Whitchurch Lock cutting was built through an island in the river and public access to the lock over the weir from Pangbourne or across the millstream at Whitchurch-on-Thames was closed in 1888 to avoid the loss of tolls on Whitchurch Bridge; as a consequence Whitchurch Lock is the only Thames lock that is inaccessible by foot - it is only accessible by boat.[9] Cookham Lock is still accessible although is not on the Thames Path. The Thames divides into several streams here and the towpath does not connect up without ferries; access to this lock requires a 10 minute walk across Odney Common on Formosa Island and the Lock Island (former Mill Eyot) to Sashes Island. Marlow Lock is a short walk from the Thames Path. All the other locks have obvious access from the Thames Path. Lock building by the Thames Commissioners had improved the whole river navigation from Inglesham to the upper limit of the tidal reach at Staines by 1789. On the tidal Thames below Staines, six new locks were built by the City of London Corporation to improve the navigation between 1811 and 1815.

There is a Thames Path on both sides of the river downstream of Teddington Lock, the southern path including the original towpath as far as Putney Bridge. Due to the locks built by the City of London, the river is now tidal downstream from Teddington Lock. A further lock with a low-tide barrage (rather than a weir), was built in 1894 downstream at Richmond Lock to improve the navigation by maintaining water level upstream to at least half tide level. Today, the Port of London Authority manages the tidal river, including Richmond lock and barrage. Wharfs and jettys are generally confined to the northern (Middlesex) bank between Richmond and Putney and this stretch of tideway (known as the Upper Rowing Code Area) has special navigation rules to accommodate the activities of a number of rowing clubs and includes the course used for The Boat Race. Chiswick Eyot is on this section and is notable as being the only tidal island on the river.

Historical records state that the towpath started at Putney.[10] Downstream of Putney, there are jettys and wharfs on both banks of the river, and sections of the Thames Path(s) often have to divert away from the river around riverside buildings.[11] Since London was such a busy port, it is likely that the riverbanks were never designated as towpath. Sailing, rowing, and following the rising and falling tide were the means of movement up until the 19th century, Thames sailing barges being typical. Crossing the river was more of a priority as evidenced by the many Watermen's stairs giving watermen and passengers access to the tidal river.[12] Thames steamers became more common for transport on the tidal Thames from 1815 until the railways dominated public transport.

In central London, there is much to see (too much to list here). The Thames Path is one of the Mayor of London's Strategic walking routes. The Thames Path Cycle Route is a black-signposted route that follows the river between Putney Bridge in the west and Greenwich in the east. It mostly follows the Thames Path, but diverges in various sections, especially where the path follows a footpath-only route. It also links National Cycle Route 1 (east of London) with National Cycle Route 4 (west of London).[13]


The route of the Thames Path can be divided into these sections:

The Shepperton to Weybridge Ferry reopened 1986

Thames crossings[edit]

Bloomer Hole Footbridge built 2000 for the Thames Path

The list below shows the points going downstream where the Thames Path crosses the river between Cricklade and Teddington. Above Cricklade the Thames is a stream and in some places there may be no water except after rain. Below Teddington there are paths on both sides of the river until the Greenwich foot tunnel, after which the path is only on the south. The letter in brackets indicates whether the path downstream of that point is on the northern or southern bank (using north or south in reference to the river as a whole, rather than at that specific point *). Bridges and ferries are listed in full under Crossings of the River Thames. Islands are listed under Islands in the River Thames.

The reverse direction of the path going upstream on the non-tidal part is obtainable by following the locks up from Teddington Lock. Between Teddington Lock and Lechlade the locks divide the river into reaches and a description of the reach above each lock includes the route of the Thames Path going upstream. Locks are listed under Locks on the River Thames.
