The Capital Ring is a 75-mile (120 km) walking route encircling inner London that links the astonishing number of islands of greenery - parks, woodlands, abandoned railway lines, towpaths and nature reserves - that still survive in the very heart of the city. The Ring takes in many of London's leading attractions - for example, the Thames Barrier, Eltham Palace and Richmond Park - as well as overlooked gems such as Oxleas Meadows, the Parkland Walk and Abbey Mills Pumping Station, a Victorian extravaganza once known as 'the Temple of Sewage'. This guide, which divides the route into 15 sections, each starting and finishing at a public transport point, is packed with vast amount of information which will guide walkers to the many and varied treasures that lie along the Ring's route.
