  • 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.

    Rivers, canals and stretches of open water are the perfect antidote to urban living – which is one of the reasons thousands of volunteers help us rewild and protect them every year.

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