Sardasht is situated in the southwest of the province and near the borders of Iran and Iraq. It has natural beauty and the inhabitants of this area believe Sardasht to be the birthplace of Zoroater. This area was formerly known as Zartosht, whereas after the Arab invasion to Iran, the name changed to Sardasht.
Kurds are the dominant ethnicity in Sardasht. Sardasht is also known for the many villages around it and their reliance on the city's market.
Sardasht, far from the frontline, was notably attacked with chemical weapons by Iraqi forces under Saddam Hussein during the Iran–Iraq War. It was the first deliberate chemical attack against Iranian civilians.
