Welcome to The River Thames Society

Members of The River Thames Society are dedicated to protecting and preserving the natural beauty of the River Thames.

 

The Thames is one of the World's most fascinating and beautiful rivers. From source to sea, its 215 miles flow from springs in Gloucestershire through rural and developed areas to London and on to the imposing tidal estuary into the North Sea.

 

Protecting the River Thames: Join the Society

The River Thames has always been an essential part of life in the south of England, but it's now under threat. From crumbling infrastructure to declining environmental health, the challenges facing the Thames, especially the non-tidal stretches, are real — and they are escalating.

​

 

​

The River Thames Society is here to make a difference. We are dedicated to listening, protecting, and restoring the Thames, working for its future health, and ensuring that future generations will be able to enjoy this beautiful waterway as we have.​​
