The Thames Path is a National Trail, 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.
The London Thames Cycle Route is a mapped (and black signposted) route that follows the river between Putney Bridge in the west and Greenwich in the east. This follows the majority of the Thames Path, but does divert 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).
The route can be divided into sections as follows:
- Thames Head (source of the river west of Cricklade) to Oxford (54 mi or 87 km): a generally rural, agricultural area, where the river is sometimes difficult to follow, particularly until Lechlade (23 mi or 37 km) is reached.
- Oxford to Henley-on-Thames (51 mi or 82 km): passing through Abingdon, Dorchester, Wallingford, Streatley and Reading: the walk leaves the river bank through the towns, and crosses from one bank to another at various places.
- Henley to Windsor: (23 mi or 37 km): through Marlow and Maidenhead. The path leaves the river on some occasions.
- Windsor to Richmond (28 mi or 45 km): along the edge of a portion of Windsor Great Park; past Runnymede; through Hampton Court Park. The path leaves the river to make way for residential areas at times.
- Richmond to the Thames Barrier (28 mi or 45 km): Passing Kew Gardens and the Wetlands Centre at Barnes then through London, using parkland (e.g., Battersea Park) to continue beside the river. Through most of the section, the Thames Path is actually two paths, one on either side of the river.
- Thames Barrier to Crayford Ness, just beyond Erith (10 mi or 16 km), connecting with the London Outer Orbital Path. This is considered an extension of the Thames Path (as recognised by the Ramblers Association) and was opened in 2001, but is not part of the National Trail. It has its own Thames Barge symbol, and is sometimes referred to as the Thames Path Southeast Extension.
Thames crossings 
The list below shows the points going downstream where the 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.
