Carshalton to Collier's Wood via the Wandle Trail
A Leafy Riverside Walk Through London's Suburbs
This surprisingly green route takes you through the south-western suburbs of Greater London. The walk is linear, beginning at Carshalton Station, with tube and bus connections to return to your starting point. The direction is easily followed by staying beside the river (usually on the west bank), and you will hardly notice that the gradient is entirely downhill apart from one set of steps crossing a railway line. The River Wandle rises in the foothills of the North Downs from ponds at Waddon and Carshalton, flowing for 12 miles through Croydon, Sutton, Merton, and Wandsworth to join the Thames upstream of Wandsworth Bridge.
