The Dead Sea’s shores sit at the lowest elevation on land on the planet. The Dead Sea is not really a sea at all, but rather a salt lake, bordered by Jordan and Israel. It is the seventh saltiest body of water on Earth— the Don Juan Pond in Antarctica is the saltiest.
Even for the strongest of swimmers, these waters can be challenging. Knowing what the conditions are before you swim is the safest way to enjoy swimming in lakes, rivers, and oceans.
