Oxburgh Hall in Norfolk being a notable one. (It's owned by the National Trust and is a wonderful place to visit.)
He actually started his journey in the Isles of Scilly, off Cornwall, and thence into Cornwall itself. I was particulary interested in his swim in the outdoor lido in Penzance because this is where I swam as a child. The pool has recently been refurbished after being virtually destroyed by yet another Atlantic storm. Its triangular shape is apparently unique in the UK, something I didn't realise.

After that he swum all over the place, a lot in East Anglia as previously mentioned but also Scotland, Devon and Dorset, Sark in the Channel Islands, the Leeds & Liverpool canal, Lidos in London, remote mountain lakes in Wales, to name but a few.
It's quite hard to review books like this which meander almost as much as the rivers Deakin was swimming in. That's because his thoughts on all kinds of things take up as many pages as the actual swimming. We get a lot of history, topography, and musings on all kinds of topics, plus interesting bits on the people he meets, things that have happened to them and so on. The book is fascinating... it took me a month to read and I'm quite pleased about that as it meant I could savour it in detail and enjoy the wonderful laid back, contemplative nature it exudes. The sad thing is Roger Deakin died in 2006 aged 63. A sad loss to British nature writing.
Next: Three Men in a Boat - Jerome K. Jerome
One parallel I must draw between Waterlog and Three Men in a Boat is that both sets of travellers found access to some parts of the rivers difficult due to private ownership and *signs* up all over the place. It drove Roger Deakin mad and also the three men in the boat. You might have thought things would've improved in a hundred years but no, apparently *not*. Interesting.
I'll be reading the second book, Three Men on the Bummel very soon... think I've already read that too but honestly don't remember it so I'm hoping it too will be a joy.
