JORDAN // Sitting between Jordan, Israel and the Palestinian Territories, the Dead Sea is the lowest point on the earth's surface at 431m/14127) below sea level. Entering its super-salty water feels more like wading into syrup. But kick your legs off the bottom and you're naturally buoyant and able to sit, roll over, and lift arms and legs in the air all while staying afloat. It's tremendous fun, and the visceral landscape -all glittering blue water, blinding-white salt deposits and swooping cragey mountains - is one of the world's most dramatic settings to take a dip.
