The Dead Sea is the lowest place on Earth and one of the strangest bodies of water on the planet. Sitting around 430 meters below sea level on the border between Israel and Jordan, it is so salty that nothing lives in it and so dense that you cannot sink. Walk in, lean back, and the water holds you up like a chair. This guide explains what the Dead Sea actually is, why it behaves the way it does, what there is to see along the shore, and how to visit, whether you come for an hour of floating or a full day in the Judean Desert.
What is the Dead Sea?
The Dead Sea is not really a sea at all. It is a landlocked salt lake in the Jordan Rift Valley, the deep geological crack where two tectonic plates slowly pull apart. The Jordan River flows in from the north, but no river flows out. In the relentless desert heat the water evaporates faster than it is replaced, leaving its salt and minerals behind. Over thousands of years this has concentrated the lake into the dense, oily, intensely salty water you float in today.
The name suits the water rather than the surroundings. Almost nothing survives in the lake itself, no fish, no plants, just salt and mineral deposits. Yet a few minutes from the barren shore lie freshwater springs, date plantations, and the desert oasis of Ein Gedi, where ibex and rock hyrax live among the waterfalls. That contrast, dead water beside living oasis, is part of what makes the place unforgettable.
Why do you float in the Dead Sea?
This is the question almost everyone asks, and the answer is simple physics. The water is around 34 percent salt and dissolved minerals, close to ten times saltier than the ocean. All that dissolved material makes the water far denser than your body, so you bob on the surface instead of sinking into it. You do not swim in the Dead Sea so much as lie on it.
The classic photo, floating on your back reading a newspaper, genuinely works. What surprises first-timers is how little control you have: rolling onto your front is awkward and getting your face near the water is a bad idea. The float is effortless, but it is its own skill.
The minerals and the famous mud
The water and the black mud along the shore are loaded with magnesium, potassium, calcium, and bromide. People have travelled here for their skin and joints since antiquity. Herod the Great built one of the world's earliest health retreats nearby, and the mineral cosmetics of the Dead Sea have been prized for over two thousand years. The science behind the health claims is still debated, but the tradition is genuinely ancient and the soft-skin feeling afterward is real enough that visitors keep coming back for it.
The ritual is straightforward. Scoop the black mud from the shoreline, smear it over your skin, let it dry in the sun for about ten minutes, then rinse it off in the lake or under a freshwater shower. At the public beaches the mud is free to dig yourself. For the geology and chemistry behind the lake, the Dead Sea entry on Wikipedia goes into real depth.
What to see along the Dead Sea
Ein Bokek, the main beach resort
If you want facilities, Ein Bokek is the place. This southern resort strip has a row of hotels fronting clean, free public beaches with showers, shaded areas, sun loungers, and cafes within walking distance. It has lifeguards in season and is the most comfortable spot for families or anyone who wants a cold drink and a bathroom close at hand. Most organised trips bring you here.
Ein Gedi Nature Reserve
A short drive north of the resort strip, Ein Gedi is the green counterpoint to the salt lake. Spring-fed waterfalls tumble into freshwater pools, the trails are walkable for most fitness levels, and wild ibex pick their way along the rocks while plump rock hyrax sun themselves near the paths. It is the easiest way to understand how this desert supported life for thousands of years. Entry is through the Israel Nature and Parks Authority for a modest fee, and the reserve closes in the late afternoon, so go in the morning.
Masada, on the cliffs above
Rising on a desert plateau just above the shoreline, Masada is the natural pairing with a Dead Sea visit. King Herod built a palace fortress on the summit, and it later became the site of the famous last stand of Jewish rebels against Rome in 73 CE. You reach the top by cable car or, for the energetic, the Snake Path at sunrise. The views over the lake and the desert are the finest in the region. It is a UNESCO World Heritage Site, listed for both its history and its dramatic setting. If you want both in a single day, see our Dead Sea and Masada day trip guide.
How to get to the Dead Sea
The Dead Sea is an easy day trip from most of central Israel. There is no train to the shore, so the realistic options are a guided tour, a rental car, or a limited bus service.
From Jerusalem, the drive to the Ein Bokek resort area is about 1 hour 30 minutes along Route 1 and then Route 90. From Tel Aviv, plan around 2 hours. A rental car gives you the freedom to add Ein Gedi or the desert on your own schedule, and parking at the public beaches is straightforward. Egged buses run from Jerusalem toward Ein Gedi and Ein Bokek, but schedules are limited and slow with beach gear. The simplest option for most first-time visitors is a guided day tour, which handles the desert driving, the timing, and the beach entry, and usually pairs the Dead Sea with Masada so you see two headline sights at once.
Best time to visit the Dead Sea
October through April is the most comfortable, with warm but manageable temperatures. Summer, from June to August, regularly climbs above 40 degrees Celsius in the desert basin, so if you visit then, start early and limit your time in the sun. Winter is mild and quiet, pleasant for the Masada climb, though the water feels cool. The Dead Sea is worth visiting year round, the season just sets the pace of your day.
Know before you go
- Do not shave for 24 hours before. The salt finds every nick. This is the most common rookie mistake.
- Keep the water out of your eyes and mouth. If it stings, rinse with fresh water immediately, do not rub.
- Float, never swim face down. Lie on your back and let the water hold you.
- Limit your float to 20 to 30 minutes. The minerals are drying and longer is not better.
- Wear water shoes. The salt crystals on the lakebed are sharp underfoot.
- Bring sun protection and water. You are in a desert basin where the sun is strong even in winter.
- Old, dark swimwear only. Salt and mud are tough on light fabric.
Is the Dead Sea drying up?
Yes. The water level is falling by roughly a meter a year, mainly because so much water is diverted from the Jordan River before it ever reaches the lake, alongside mineral extraction at the southern end. The shoreline has receded noticeably over recent decades, and sinkholes have appeared where fresh groundwater dissolves buried salt. Efforts to stabilise the lake have been discussed for years. None of this stops you visiting, but it is part of why seeing the Dead Sea now, while it remains one of the world's great natural wonders, has its own quiet urgency.

Frequently asked questions about the Dead Sea
Why do you float so easily in the Dead Sea?
The water is around 34 percent salt and minerals, close to ten times saltier than the ocean. That makes it far denser than the human body, so you float on the surface without any effort. You cannot really swim in it, you simply lie back and the water holds you up.
What is the best time of year to visit the Dead Sea?
October through April is the most comfortable, with warm but manageable temperatures. Summer regularly climbs above 40 degrees Celsius in the desert basin, so if you visit then, go early in the morning and limit your time in the sun.
Is the Dead Sea safe to swim in?
It is safe to float in if you follow the basic rules: do not put your head under, keep the water out of your eyes and mouth, and do not swallow it. The salt is harmless on intact skin but stings cuts and sensitive areas. Public beaches at Ein Bokek have lifeguards and freshwater showers.
Is the Dead Sea mud really good for your skin?
The black shoreline mud is rich in magnesium, calcium, and potassium, and people have used it for skin and joint care since antiquity. Many visitors notice their skin feels softer afterward. Apply it, let it dry for about ten minutes, then rinse it off in the lake or a freshwater shower.
How long does it take to get to the Dead Sea?
From Jerusalem the drive to the Ein Bokek resort area is about 1 hour 30 minutes. From Tel Aviv it is roughly 2 hours. Most visitors come on a one-day trip, often combined with Masada, which sits directly above the shoreline.
Can you visit the Dead Sea and Masada in one day?
Yes, and it is the most popular way to do it. Masada sits on the cliffs directly above the Dead Sea, so a single day trip comfortably covers the clifftop fortress in the morning and a float in the lake afterward. See our Dead Sea and Masada day trip guide for the full plan.
Is the Dead Sea drying up?
Yes. The water level is falling by roughly a meter a year, mainly because so much water is diverted from the Jordan River before it reaches the lake. The shoreline has receded noticeably over recent decades, which is part of why visiting it now has its own appeal.
