It took 40 minutes for us to drive to the sea. Amman being at 3,000 ft. above sea level, and the Dead Sea at -1,400 ft. made our drive a nice downhill excursion wrapping through many large sandstone hills and "mountains." You can't just pull off the road and hop in at the Dead Sea, the only way to experience it is through one of the hotels lining the shore.
This is the view from the hotel we stayed at for the day. You purchase a day pass which is pretty expensive, but food and drinks are also part of the package. Almost everybody spends their time by the pools rather than on the "beach" of the Dead Sea. If you can see through the haze, the outline of mountains on the other side is Israel.
The Dead Sea is amazing in the sense that you literally float without trying. I tried touching the bottom, but couldn't get any farther down than my neck. You lie back and immediately float. I figure it must be similar to feeling weightlessness in space.
Below are a few more pics of the Dead Sea.
