Yes, you can wear a bathing suit in the Dead Sea, but in 2026, experienced travelers offer a stern warning: choose an old or "disposable" suit. The Dead Sea has a salt concentration of roughly 34%, which is nearly ten times saltier than the ocean. This extreme salinity is harsh on fabrics; it can leach the elasticity out of Lycra and Spandex, cause colors to fade significantly, and leave a permanent "oily" residue that is difficult to wash out. Furthermore, if you partake in the famous mineral mud baths along the shore, the dark mud can permanently stain light-colored fabrics. It is also essential to wear water shoes or old flip-flops while in your suit, as the "sand" is actually made of jagged, razor-sharp salt crystals that can easily cut your feet. After your float, you must rinse your suit (and yourself) immediately in the freshwater showers provided at the beach to prevent the salt from crystallizing and further damaging the garment.
