We all know that one of the best ways to see more of London is on foot, and that a guide-led walk can reveal many lesser-known aspects of the city. That probably explains the popularity of the Walk London programme which has been organising free guided walks within the capital since 2007. The walks, funded by Transport for London and delivered by Walk Unlimited, happen three times a year, in January, May and September. The next weekend takes place on the 28 and 29 January 2017. There’s a large variety of walks available in the weekend, from short family strolls to full-day countryside hikes. There is no charge, but you will need to book your place in advance on the Walk London website. The site gives details of all the walks on offer, from Little Venice and Camden, Soho and the West End, the hidden alleys of the City, Bushey Park – there are over 40 to choose from. Places do go very, very quickly, but you can sign up for the Walk London mailing list to be alerted when each new programme becomes available.
