Can you swim in the Dead Sea? No, not really. The water can hurt your eyes and be poisonous if swallowed. But you can float. The high salinity causes a natural buoyancy. Just enter the water and slowly lay back. Now raise your arms. Or read a book. Drift aimlessly. If you want to capture the moment with a selfie, be extra careful. The salt water can quickly render your cell phone or camera useless. Another word of caution is to avoid shaving for a day or two before visiting the Dead Sea. Otherwise, the salt water can surprise you with the equivalent of razor burn.
