Kangan in BUSHEHR Province lies in the extreme south eastern region of the province on the coast of Persian Gulf. Bandar-e-Taheri being one of its districts, was an important center of trade and commerce in the 4th century AH. The Port of Siraf or 'Bandar-e-Siraf', west of this region was one of the largest ports of Iran in the Persian Gulf and after Shiraz it ranked as the second city of the province of 'Ardeshir Khoreh'. The Thermal spring of 'Mianloo' north of Kangan is a place worth seeing.
