Capritage Helwan
Helwan, Egypt
Ain Helwan (Arabic: كابريتاج حلوان), also known as the Helwan Sulphur Springs, Helwan Baths, or the Helwan Sulphur Center for Natural Medicine, Rheumatology, and Rehabilitation (and more commonly as Helwan Sulphur Baths), is one of the most famous sulfur water springs in Egypt. Its fame stems from the high concentration of treated sulfur, reaching up to 27%. There are two springs in Helwan: one located near the Ain Helwan Metro Station, and another, also called Helwan Baths (or Helwan Sulphur Baths), which is the more well-known one on Mansour Street.
