This is our regular Autumn River Clean-Up facilitated by the excellent Thames21 (www.Thames21.org.uk) who provide equipment, safety guidance and leadership at the event. This is always great fun and it doesn't matter if you've not been before as everyone's welcome. Under-16s must be accompanied by a responsible adult.
Meet by Ladywell Fields Adventure Playground at the far end of Malyons Road, Ladywell, London SE13.
