The Green Chain Walk is a network of paths in south-east London that connects locations including the Thames Barrier, Thamesmead and Erith along the river, and at the other end Crystal Palace and Chislehurst.

The route was created in 1977 by a joint team of four London boroughs. What makes it distinctive is the way it connects parks and other open spaces as far as possible, including fragments of ancient woodland at Oxleas and Lesnes Abbey Woods, heathland at Plumstead Common and large parks such as Avery Hill and Crystal Palace. The longest continuous route is Thamesmead to Crystal Palace (26.5km), with many links making up the total of 64km.

The Capital Ring is a surprisingly green route that encircles London. Distance is 78miles; it threads together parks and open spaces, mostly following pleasant residential roads in between. The route is an initiative of the London Walking Forum. The route is very well signed, with a Big Ben logo TQ1678 : Three walk logos, Gallows Bridge. The route is a walker’s equivalent of the North and South Circular roads. Link
