  • It’s part of the longest river in England, it has 45 locks, is home to over 25 species of fish, boasts three areas of outstanding natural beauty and it’s the only river in Europe to have a national trail follow its entire length.
  • It flows into the North Sea.
  • The river passes numerous popular cities along its way, such as London, Reading, Hendley-on-Thomas, Windsor and Oxford, where it is also called the Isis River.


  • The main tributaries of the River Thames are: Lea (68 km), Leach (30 km), Churn (37 km), Coln (52 km), Windrush (48 km), Kennet (77 km), Evenlode (68 km), Ock (37 km), Loddon (32 km)
