I used this guide while walking in London two years ago, and I'm taking it to London again this summer. The variety of walks is a joy. I did not see this book on sale while in London, and some English friends saw mine and wanted a copy for themselves. No wonder--it's that good. If you like to walk and do other exploring besides the usual London tourist things, then don't go to England without a copy of this book in your suitcase or backpack. My only suggestion to the author is to bind future editions of the the book in a way that the chapters can be removed and replaced. So I wouldn't have to carry the whole book along, I tore the pages out for each walk I did, and then taped them back in place afterward, but there must be a better way.
