Overview

Badab-e-Surt are beautiful travertine terraces in northern Iran and they are an incredible natural phenomenon that developed over thousands of years. Travertine is a type of limestone formed from the calcium deposit in flowing water, and in this case it's two hot springs with different mineral properties. The unusual reddish colour of the terraces is down to the high content of iron oxide in one of the springs.
