We took a day trip to the Dead Sea, which is over 33% salt and is the lowest land on the planet (somewhere around 1200 ft below sea level). "Swimming" in the Dead Sea requires no effort whatsoever because of the increased buoyancy. In fact, it's nearly impossible to swim under the water. Even standing straight up and down in deep water, I couldn't get my head below the surface...I just kept bobbing back back up.
