The original map was heritage and walk based (although the first, more limited version appeared some years earlier concentrating on disability access to the River Wandle), but then a revised map was produced by Groundwork Merton to facilitate bicycle access.
The group consist of an association of the London Boroughs of Wandsworth, Merton and Sutton, together with Groundwork Merton (a charity to support the improvement of the quality of life for Londoners), Sustrans (a charity for sustainable transport, especially cycling), and Wandle News (a website containing news and information about the Wandle Trail.
Schemes have been presented for future development that may overcome the obstacles by the river, but cost has so far prevented their implementation.
In addition to the parks, the trail is adjacent to both Morden Hall (National Trust) and Merton Abbey Mills, which has a working waterwheel.
There are several parts of the trail that are suitable for nature and ecological study, and some places where fishing is allowed.
