Welcome to Thames21
We reconnect people to nature by helping them enjoy, protect and enhance their local rivers.
Whether it’s the Thames or one of its many tributaries, we offer inspiring ways for communities to get down to their local riverbank.

Our aim is to rebuild the relationship between communities and their rivers; restoring river health and boosting wellbeing and community cohesion in the process.
