Walk to see all of the London sights?
Hi everyone, my sister is coming to stay with me (currently lives in Hong Kong!) and I want to show her all the usual sights of London in one day. Can you recommend a good route or point me in the direction of any good walking resources? I know it must be doable but, I must admit I don't often go into Zone 1, and don't know it very well at all! Any advice would be amazing, thanks
