This was one of my favourite walks and stuff to do when I was living in London. You can do the walk in an hour or so...if you walk fast, or you can make it into a whole day thing by visiting some of the museums, sitting in the park, indulging in the buzz around Harrods and spending your last pennies at the cafe's on Walton Street.
