The Capital Ring is a 78-mile (125 km) walking route encircling inner London that links the astonishing number of islands of green space - parks, woodlands, abandoned railway lines, towpaths and nature reserves - which still survive in the very heart of the city.

For 140 miles, the London LOOP (London Outer Orbital Path) follows a green corridor right around the capital, offering a circular walk among secret countryside.

The North Downs Way is the official guide to the National Trail that follows the North Downs, from the Hog's Back in Surrey all the way to the white cliffs of Dover.
