Badab-e-Surt
est un site naturel de la province de Mazandaran. Il comprend une série de terrasses de travertin en gradins créées depuis des milliers d’années.
Badab Sourt is made of a range of stepped travertine terrace formations thousands of years ago, as flowing water from two hot mineral springs cooled and deposited carbonate minerals on the mountainside.
Badab is a Persian compound of Bād "gas" + āb "water", translating to "gassed water", referring to the springs' waters being carbonated mineral waters.
It is at a height of 1,841 meters above sea level
The Badab Sourt Spring is actually comprised of two separate springs with completely different colored and scented water. The first spring contains very salty water that gathers in a small natural pool.
The high level of salt in the springs keeps it from freezing during the winter.
The Badab Sourt Spring has been registered as a national heritage site.
There are similar sites in the US, New Zealand and Turkey from which only the Pammukkale in Turkey is a tourism hub.
