Badab-e Surt's springs are two distinct mineral springs with different natural characteristics, located at 1840 meters of altitude. The first spring contains very salty water that gathers in a small natural pool; its water is considered to have medical effects, especially as a cure for rheumatism and some types of skin diseases and skin conditions. The second spring has a sour taste and is predominately orange mainly due to the large iron oxide sediments at its outlet.
