TheThames Path is aNational Trail following theRiver Thames from one of its sources nearKemble in Gloucestershire to theWoolwich foot tunnel, south east London. It is about 185 miles (298 km) long.[1][2] A path was first proposed in 1948 but it only opened in 1996.[3][4]
In theory, the Thames Path's entire length can be walked, and a few parts can be cycled, but certain sections are closed for an indefinite period, including Temple Bridge at Hurley and Marsh Lock in Henley (see section below). Some parts of the Thames Path, particularly west ofOxford, are subject toflooding during the winter. The river istidal downstream fromTeddington Lock and the lower parts of these paths may be underwater at spring tides, although theThames Barrier protects London from catastrophic flooding.
The Thames Path uses the rivertowpath between Inglesham and Putney and available paths elsewhere. Historically, towpath traffic crossed the river using manyferries,[5] but few of these crossings exist now and some diversion from the towpath is necessary.
The Thames Path meetsThe Ridgeway National Trail at theGoring Gap, where the trails use opposite banks of the River Thames betweenGoring-on-Thames andMongewell; the Thames Path follows the western bank and The Ridgeway the eastern.
The general aim of the path is to providewalkers with a pleasant route alongside the river. The way this is achieved naturally falls into three distinct areas, depending on the nature of the river in the area.
In the absence of a tow path, the Thames Path uses all available riversiderights of way between the traditional source of the river inTrewsbury Mead andInglesham, but is unable to run alongside the river in several places.
The Thames Path starts beside the monument for the traditionalriver source and follows the water down the hill towards theFosse Way. In the fields either side of theA433 are somesprings; and south of this road, a smallwater channel can be found and then a pool and small weir, before reaching theA429 bridge near Kemble. On the stretch between Ewen andSomerford Keynes thebourne passes through fields and there are a number ofwatermills.[6] The path then follows the watercourse through theCotswold Water Park toAshton Keynes, where the water divides into a number of streams; the Thames Path partly follows one of these and rejoins the river by Waterhay Bridge.[7] Downstream from this point canoeing in the river is practical. The path wanders to and from the river amongst moregravel pits until Hailstone Hill, where a riverside path starts by the old railway line. A little further, theNorth Wilts canal fromLatton formerly crossed the river on anaqueduct and ran alongside and south of the river to West Mill Lane.[8] Here the path leaves the river to go throughCricklade, pastCricklade Town Bridge, rejoining the river east of the town, and now follows the river all the way downstream toCastle Eaton. The path next followscountry lanes, a short stretch along a backwater toHannington Bridge then goes across fields to Inglesham.[9] In 2018 the path incorporated a section ofpermissive path alongside the river at Upper Inglesham.[10]
Above Inglesham the river is notdredged and being withoutweirs to control water levels, it is often shallow, weedy and swift but after heavy rain flooding of the riverside paths is common. Today theEnvironment Agency (the current successor to the Thames Conservancy) is thenavigation authority responsible for the Thames between Cricklade and Teddington. The navigation towpath starts from Inglesham (just upstream of Lechlade), as does the ability to navigate the river for all but very small boats, although there were once weirs withflash locks to enable passage as far as Cricklade, and there is still a right of navigation up to Cricklade.[11] The navigation above Lechlade clearly must have been neglected after theThames and Severn Canal provided an easier route by canal for barge traffic[12] and not all of the river downstream from Cricklade has a footpath alongside.
The Thames Path uses the existing Thames towpath between Inglesham andPutney Bridge wherever possible. The former Thames and Severn Canal entrance is the present-daylimit of navigation[13][14] for powered craft, and is one and a half miles upstream of the highest lock (St John's Lock), nearLechlade.[15] 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 notmill streams,backwaters or a fewmeanders cut off bylock cuttings, since towpaths were originally only intended to enable towing of barges on the navigation.

The Thames has been used for navigation for a long time,[12] although owners of weirs,locks and towpath often chargedtolls. The towpath owes its existence, in its current form, to theIndustrial Revolution and theCanal Mania of the 1790s to 1810s, and so is related to thehistory of the British canal system. The Thames already allowed for passage onto theRiver Kennet Navigation andRiver Wey Navigation, but this period in history also saw theWilts & Berks Canal, theOxford Canal and theThames and Severn Canal connected to the non-tidal Thames. It was not until a little after theThames Navigation Commission were enabled theThames and Isis Navigation Act 1795 (35 Geo. 3. c. 106)[16] 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 ofhorse-drawnbarge traffic to travel upstream to the Thames and Severn Canal, which had opened in 1789 and provided an alternative route (also using the Wilts & Berks Canal) for boat traffic to Cricklade. The commissioners had to create horse ferries to join up sections of towpath (for example atPurley Hall), as the act did not allow them to compulsorily purchase land near an existing house, garden or orchard. TheCity of London Corporation, who had rights and responsibilities for the Thames belowStaines from a point marked by theLondon Stone, had similarly bought out the towpath tolls of riparian land owners as enabled by the earlierThames Navigation Act 1776 (17 Geo. 3. c. 18).[12]
From the 1840s, thedevelopment of the railways andsteam power gradually made redundant the need for horse-drawn barges on the non-tidal Thames, although people were still using the towpath to tow small pleasure boats in 1889.[17] The towpath route has not changed since then, apart from now following Shifford lock cut; however, over time the towpath ferries became obsolete and the last towpath ferry to stop running was therope ferry at Bablock Hythe in the 1960s.[18]
The main exception to towpath access to the navigation between Inglesham and Putney is a stretch of river where the former towpath was removed pastWindsor Castle. The castle's private grounds ofHome Park, Windsor were extended to include the riverbank and its towpath by theWindsor Castle Act 1848 (11 & 12 Vict. c. 53), also involving the building ofVictoria andAlbert bridges and the removal ofDatchet Bridge.[19] This accounts for the Thames Path's diversion from the river atDatchet. There are two other short lengths of navigation which have no towpath: one between Marlow bridge and lock (which never had a towpath), and one past Whitchurch lock either side of The Swanpublic house inPangbourne (where the towpath has been lost). At both these weirs, lengthy ropewinches were required for barges to pass Marlow and Whitchurch in the days before steam power. It is also required to divert around Oxford Cruisers downstream ofPinkhill Lock, even though the towpath is still shown as a public right of way on Ordnance Survey maps.[20] The remainder of the navigation between Inglesham and Putney has an existing towpath; however, river crossings are now missing at the sites of 15 former ferries and one former lock, so the Thames Path makes 11 other diversions from the remaining towpath because of the lack of a river crossing at their original locations. There is also a twelfth temporary diversion at Hammersmith Bridge, described below.
Walkers can visit the lengths of river navigation not on the Thames Path using the current towpath, except for two isolated sections of towpath not connected by any public path (or ferry) at either end. The first is a short section of path on the north bank opposite Purley-on-Thames; this is still shown onOrdnance Survey maps but is inaccessible except by boat, caused by the lack of two ferries formerly diverting around Purley Hall.[21] The second and furthest downstream is a particularly picturesque section of towpath (again shown on OS maps) within theNational Trust grounds ofCliveden; here the lack of three ferries accounts for the Thames Path's diversion from the river atCookham.[22]
When Cookham Lock was built in 1830,Hedsor Water became a backwater and lost its towpath. Around 1822, Clifton and Old Windsor locks were built, with lock cuttings which cut across river meanders; here the towpath was rerouted along the lock cuttings and there is no public riverside access to these river meanders. However, some stretches of river bypassed by navigation cuttings still retain public footpath access: firstly atDesborough Island (formed byDesborough Cut); secondly, parts of older towpath accessible atDuxford (towpath now followsShifford Lock cut); and lastly, the river meander at Culham. The Culham meander is accessible, even though only parts are designated as public footpath (towpath now followsCulham Lock cut) and there is also riverside public footpath along the ancientcauseway pastSutton Pools.[23]
Certain sections are closed indefinitely for reasons such as bridge failures. The closure between Shiplake and Henley involves a diversion of 2.7 miles (4.3km), taking about 1hr 15 minutes to walk.[24] The bridge at Hurley is also closed. Details of all closures are shown on the trail's interactive map.[25]
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 (the towpath ferry was upstream).[26] In recent times, crossings have been created for the Thames Path; theShepperton to Weybridge Ferry was restarted in 1986,Temple Footbridge nearHurley was built in 1989, a footpath was attached toBourne End Railway Bridge in 1992 (the ferry was upstream),[27] andBloomers Hole Footbridge was built in 2000. No other replacement river crossings have been created for lapsed ferries, so the Thames Path must divert away from the river and the towpath to cross the river elsewhere, leaving some sections of towpath not on the Thames Path.
Many walkers visit thelocks on the River Thames and in summer some have facilities open for visitors. A few have smallcampsites. The locks at Cookham and Whitchurch are not on the Thames Path and require some effort to visit.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 onWhitchurch Bridge; as a consequence, Whitchurch is the only Thames lock that is inaccessible by foot – it is only accessible by boat.[28]Cookham Lock is still accessible although it 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 onFormosa Island and the Lock Island (incorporating the former Mill Eyot) toSashes Island.[29]Marlow Lock access requires a short walk through town back streets. All the other locks have obvious access from the Thames Path.
The lock islands atPinkhill Lock,Eynsham Lock,King's Lock,Boulters Lock andShepperton Lock can be visited, as canPenton Hook Island which is ameander cutoff formed whenPenton Hook Lock was built. Any public footpaths that cross or go along any of the other small islands formed by construction of the Thames locks only allow access to the path alone.
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. TheThames Conservancy was established in 1857 to take over duties from the City of London because of falling revenue from boat traffic; it also took on the duties of the Thames Commissioners in 1866.[16] Provision for pleasure boating was now the main purpose,[17] and although the Thames Conservancy rebuilt many locks, upgrading some from flash locks to pound locks, and made navigation and towpath improvements, it only built one completely new lock on the non-tidal Thames, at Shifford in 1898.
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.
Because of the locks built by the City of London, the river is now tidal only downstream from Teddington Lock, although during spring tides flood warnings are sometimes issued upstream towardsMolesey Lock. A further lock with alow-tide barrage (rather than a weir) was built by the Thames Conservancy in 1894 downstream atRichmond Lock to improve the navigation by maintaining water level upstream to at least half-tide level. Today, thePort of London Authority is thenavigation authority that manages the tidal river, including Richmond Lock and barrage.Wharfs andjetties are generally confined to the northern (Middlesex) bank between Richmond and Putney. This stretch of tideway (known as the Upper Rowing Code Area) has special navigation rules to accommodate the activities of a number ofrowing clubs, and includes the course used forThe Boat Race.Chiswick Eyot is on this section and is notable as being the onlytidal islandon the river.
Since August 2020, the towpaths on both banks have been closed underHammersmith Bridge because of cracks in the structure; walkers and cyclists must therefore divert from the river at the bridge until they reach the adjacent road (Castelnau on the south bank, Hammersmith Bridge Road on the north) and then cross the road at the nearest safe point before returning to the river.

Historical records state that the towpath started at Putney.[30] Downstream of heresailing,sculling androwing, and following the current (or rising and falling tide) were the means of movement until the 19th century,[17]Thames sailing barges being typical. Moderately straight lengths of the tideway are often calledreaches, as they can be sailed withouttacking. Crossing the river was more of a priority, as evidenced by the manywatermen's stairs givingwatermen and passengers access to the tidal river.[31]Thames steamers became more common for transport on the tidal Thames from 1815 until the railways dominated public transport. Falling income from river traffic and disputes over the construction ofVictoria Embankment because ofCrown Estate ownership of the tidal riverbed[32] led to the City of London's seceding management of their part of the river to the Thames Conservancy in 1857; and the section below Teddington was further passed on to the Port of London Authority in 1908. Construction of riverside buildings and structures often meantembanking the tidal Thames and acquiring riverbed ownership. The historical progression of so many construction works, is why there is not continuousforeshore access for a riverside path within thePort of London. Today, downstream of Putney, there are jetties and wharfs on both banks of the river, and sections of the Thames Path often have to divert away from the river around riverside buildings.[33] There are also manydocks, most of them downstream ofTower Bridge.
Incentral London, there is much of interest. The Thames Path is one of theMayor of London'sstrategic walking routes.[34] 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 linksNational Cycle Route 1 (east of London) withNational Cycle Route 4 (west of London).[35]
The route of the Thames Path can be divided into these sections:


The list below gives the points where the Thames Path crosses the river between Cricklade andTeddington. 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 theGreenwich foot tunnel, after which the path is only on the south.
The list is in downstream order. The letter in brackets indicates whether the path downstream of that point takes 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 underCrossings of the River Thames.The river can be crossed at about a third of the locks, although some of these crossings are not part of the Thames Path.
