help Thames River FAQ

Is the Thames really England's longest river?

The Thames is about 346 kilometers long and is the longest river flowing entirely within England. The Severn is longer overall, but part of its course runs through Wales.

Where does the River Thames begin and end?

The traditionally recognized source is at Thames Head in Gloucestershire. The river flows through Oxford, Windsor, and London before widening into the Thames Estuary and reaching the North Sea.

Why does the Thames rise and fall in central London?

The Thames is tidal through London, so North Sea tides move upstream beyond the city. The Thames Barrier near Woolwich helps protect the capital from dangerous storm tides and high water.

Can people walk the full length of the Thames?

The Thames Path follows the river from its source area through London to the estuary. It is a designated National Trail and passes landmarks including Windsor, Hampton Court, and the Palace of Westminster.
