Wild swimming in the River Ray at Islip

Wild swimming is idyllic, but isn't something I get much opportunity to do in London, so when an opportunity comes along it's worth braving the mud and the misc squidgy stuff at the bottom and jump right in!

Not literally though, not until you know how deep it is.

That's just dangerous.

Speaking of danger, the Outdoors Swimming Society has a page on wild swimming safely that you ought to read if you're considering it.
