Dead Sea

The Dead Sea lies more than 400 metres below sea level, the lowest point on the surface of the Earth, and its water is almost ten times saltier than the ocean. That density means everyone floats, swimmer or not; lying back to read a newspaper is the classic photograph.

The Jordanian shore is lined with resorts that have private beaches, freshwater pools and spas, and the black mud from the shore is said to be good for the skin. A night here after Petra and Wadi Rum makes a restful end to a trip.

Do not shave on the day you swim, keep the water away from your eyes and limit each float to ten or fifteen minutes. Wear water shoes, as the salt crystals are sharp underfoot.
