Winter wandering

Transport for London (TfL) is funding the walks, which are organised by Walk London.

All the walks start and finish at a bus stop, Tube or railway station. They follow mainly traffic-free routes and connect some of London's best attractions, parks and open spaces, as well as a number of rivers.

There are break-off points on all the walks for those who would rather take a shorter route. Organisers advise anybody who wants to do the full walk to bring a packed lunch with them.

Here are TfL's top five walks:
