h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

This summer I walked the Thames Path from Windsor to the Thames Barrier. I would recommend this experience to anyone - it is extremely well sign-posted and generally well paved. You get a fantastic perspective on the contrasts in our society from extreme wealth to extreme poverty, passing through some of the most lush countryside to a brilliant walk through the heart of London. It is also easily accessed by public transport - we did it in about fifteen mile chunks and you can't easily get lost - after all the river is quite noticeable!!! If you are a confirmed city dweller then just do the London bit from Richmond to the barrier, it does give you a different perspective on some famous landmarks. If I gave more detail then on would go on to the point of being boring. I used a guide but it really wasn't necessary as the waymarking was generally good. Oh and there are any number of outstanding public houses all the way!!!

... including The Dove near Hammersmith Bridge which is in the Guiness Book of Records for having the smallest bar.

It's usually quite packed

And the old Ship Pub near Hammersmith Bridge, which is worth stopping at for a quick pint.

..not to mention the Founders Arms by the new Tate Gallery. I rest my case...
