The lowest exposed ground on Earth, over 430 metres below sea level, and so saturated with salt (roughly ten times the ocean) that you float without effort and nothing lives in it. Both Jordan and Israel run huge evaporation-pan industries here for potash and bromine, and the shore grows salt crystal formations. The sea is shrinking fast, and sinkholes make parts of the shoreline genuinely dangerous, so use the managed beaches.
