There’s a reason for the travel cliché of newspaper-readers floating in the Dead Sea’s saline-rich waters – just try swimming. Firstly, you can’t get low enough in the water to stroke. Secondly, you risk getting water in your eyes, an act that will have you screaming oaths that could wake the dead. So don’t even try. Instead, lie on your back, do the crossword and congratulate yourself on just ticking off another one from your ‘travel must-do’ list. A travel experience that can truly be labelled unique, and utterly unmissable.
