River Thames Society

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.


If you are inspired by the Society's aims and achievements and would like to help us to protect and promote the Thames, please become a River Thames Society member and join us as we continue our quest to preserve and develop the River Thames.
