At 1,412 feet below sea level, the Dead Sea is the lowest point on earth. The water is nearly ten times saltier than the ocean, making it impossible to sink. You'll bob on the surface like a cork — just lean back and float. The mineral-rich mud along the shore is famous for its skin benefits; smear it on, let it dry, then rinse in the sea.
Pair your Dead Sea visit with a sunrise ascent of Masada (the cable car opens at dawn) and a stop at Qumran, where the Dead Sea Scrolls were discovered in 1947. The combination of natural wonder, ancient fortress, and biblical archaeology makes this one of the most memorable days of any Israel trip.
Practical tips: don't shave the morning of your Dead Sea visit (the salt stings). Wear old sandals you don't mind getting muddy. Bring a waterproof phone case for photos. And absolutely do not splash or submerge your face — getting salt water in your eyes is extremely painful.
